The story of the why’s and how’s I’m just coming into this, after 43 years of playing, is a long one, so much so my fingertips ache from thinking about how long it’ll take to type out. But, I will say I had problems with mouthpiece work, as my fingers and hands hurt from holding it longer than a couple minutes at a time, and I had bad upper body- and face pressure problems which used to hurt my embouchure.
To the point, these are glasswork pliers, secured with a hair tie. Setting the mp on an angle as shown allows for the best grip and action. It can be squeezed pretty hard to “set”, then can be held gently with both hands. After a couple months I’ve found that it does not damage or distort the shank, which makes sense because it’s meant to hold glass firmly. Instead of a couple minutes, I can spend as long as I want buzzing - hours, even. No more aching hands and sore mouth. The days of warming up for 15 minutes on each horn before doing my most extreme playing are over; I get the horn warm (if it truly is cold), then off I go. It’s an incredible feeling of freedom. My trombone playing is beyond secure, my trumpet playing is a lot stronger, and I’ve exposed flaws in my tuba playing I never would’ve discovered otherwise. I figure by the end of the summer I won’t need to do even this; it’ll be the end of practicing forever, which is great because I have a stack of books I’ve been meaning to read.
So this is for you, brass. Maybe I invented something new, but probably not; I bet there’s some truss or harness out there that’s a lot more complicated and expensive than this tho. Pick one of these up at Amazon for under $10, some hair ties at Walgreens, and have at it.

(This case was sent my way via this post asking for case suggestions from my international readers since I focus on International cases.
So I would like to thank xzwkimin for informing me about this case. And as this case is from a country that I skipped over during America's Series, that means I am delaying the Japan case and going backward to do this one
There is also a very lengthy 1 hour long video on this case by Jackie Flores which I used as a guide since it was helpful. But rest assured, I did my own research, used by own words, included additional information and didn't just copy her.
And as you my expect from that prior statement, this is a huge case so information is surely missed so like always your own research is encouraged in case I missed anything.)
Ámbar Cornejo Llanos was born on February 14, 2004, in Villa Alemana, Chile to her mother born in 1982 and father Ulises Cornejo. Ulises was mostly absent and seemed to have separated from Denisse before Ámbar was even born. Not long after their separation, Denisse began dating a new man named Juan Carlos Pérez Aguirre, a friend of Denisse's since before Ámbar was even born. This relationship would result in them having two children and thus Ámbar having two step-siblings although one tragically passed away at 4 months old due to malnourishment brought about due to improper care. After the death, Denisse would fall into a depression, heavily drink and neglect Ámbar and her surviving brother. It got to the point where their school requested the two be removed from Denisse's custody as they were visibly not being taken care of. The request was granted and the two were removed from her custody and held in an Institution for minors.
Ámbar Cornejo Llanos
Denisse Llanos Lazcano
In 2009, Denisse had her final break up with Juan, their relationship was a dysfunctional on-again-off-again relationship with constant break ups and reunions but eventually, their final break up would come. Also in 2009, Denisse had improved enough for a court to deem it safe for Ámbar and her brother to be returned to her care. After the break-up, Denisse and Ulises appeared to reconcile and Ulises grew close to Ámbar.
On September 27, 2012, Ámbar confided in two of her school teachers that one of her friends had been sexually assaulted, after they called her friend's mother, she broke down and admitted that she had lied and was in fact talking about herself. Ámbar was taken to the police to give a statement and she told them that whenever her mother took her and her brother to visit Juan back when they were dating, Juan would sexually assault her during these visits. Juan was arrested and on November 25, 2013, The Oral Criminal Court of Viña del Mar sentenced him to three years imprisonment, ordered him to pay and cover the entire cost of the trial, prohibited him from even having any contact with Ámbar or her family, and had to disclose his address to the police. The court also again, took custody away from Denisse and sent her to live with Ulises for a few months, The no-contact order went both ways as Denisse was ordered to have nothing to do with Juan either so long as she wanted to raise Ámbar. Eventually, Ámbar was returned to Denisse's custody after she obeyed this court order.
Ulises, viewing Denisse as an unfit mother, and since he saw her as manipulative wanted to keep Ámbar. When Denisse found out, she prohibited her daughter from ever visiting her father and tried to manipulate her into disliking him, saying that it was his fault and that he was trying to break up their family. Ulises would also send money to the family for Ámbar but Denisse would often, not tell her when the money arrived and simply pocket and spend it for herself.
Denisse's plan to turn Ámbar against her father backfired and the older Ámbar got, the more strained her relationship with her mother would become. They would constantly argue and one time, Ámbar had a friend over when she and Denisse had another argument and Denisse moved to strike her daughter. Ámbar and the friend ran to another room and locked the door but Denise was so angry over whatever the fight was about that she hit the door with enough force to break it open. The only reason that Ámbar never defended herself was simple, according to friends, Ámbar told her that since Denisse gave birth to her, she was obligated to respect her mother and could never raise a hand to her.
Soon Denise would date another man, the landlord of their apartment, Manuel García Queirolo. Tragically, Manuel wouldn't be any better than Juan. Whenever he heard that Ámbar was showering, he'd use his position as the landlord to go to a room on the second floor that gave him a clear view through the bathroom window so he could watch Ámbar. Ámbar would eventually find out and inform her mother to which she told her and her brother to just not shower unless she were home. But beyond that, she took no action, she didn't even stop seeing Manuel. She actually did the opposite and got mad at Ámbar for being the subject of Juan and Manuel's lust. The worst of Manuel's depravity wouldn't come out or be known by others, even Ámbar until years later, that will be discussed further in the write-up.
With all this tragedy and her dysfunctional and abusive home life, one may expect Ámbar to have been troubled. But on the contrary, all her friends said she was happy, outgoing, kind, would do anything for them and loved to engage and share her hobbies with them such as dancing. Ámbar was deeply liked by all her classmates and was very popular. She had managed to not be defined by all that was going on in her life.
In late 2019, Denisse had found her next boyfriend, a man named Hugo Humberto Bustamante Pérez with the two moving in together in relatively short order. Ámbar was not very keen on Hugo and how fast their relationship was progressing, she also felt uneasy about him as well and how he looked at her. Ámbar told one of her friends about her mother's new boyfriend and her friend felt his name sounded familiar to the two looked him up and did not at all like what they had found.
Hugo Humberto Bustamante Pérez
Hugo Humberto Bustamante Pérez was born on March 28, 1965, in Quilpué as the third out of four siblings. His father worked as an electrician, and his mother a housekeeper with domestic violence a frequent occurrence in the household. His mother was described as neglectful while his father was actively abusive and had him put to work at the age of 8 to sell fruits and vegetables at markets. To escape his father's abuse during his most violent outbursts, he would go stay at his grandparent's house. At the young age of 13, he would fall into a drug addiction, starting with marijuana before escalating to opium and cocaine.
At the age of 15, his father kicked him out of the home so he went to Mendoza, Argentina and lived with a classmate. There he claimed to have travelled all to Bolivia, Peru, Spain and Brazil. He returned to Chile at the age of 18 and began stealing goods to sell back as well as trafficking drugs. When he was 20 he would, with the help of an accomplice take part in a scam where he would get on a bus, gain the trust of the passenger sitting next to him, offer a drink laced with sleeping pills and then steal their belongings as they passed out in the street. He would also attempt this on beaches as well.
Several times, Hugo would attempt to start romantic relationships but none of them would last particularly long usually breaking up almost immediately due to a lack of commitment from Hugo. For legitimate income, Hugo got into bodybuilding and according to him, he owned a nightclub. On May 27, 1987, Hugo was arrested for the first time on a charge of theft but he doesn't appear to have suffered severe consequences for this. He later began another relationship but this one seems to have lasted a little longer with them even having a child and Hugo getting employed as a serial guard. But they broke up shortly after the birth and in 1989 Hugo was arrested for nine counts of robbery, four counts of theft and 5 counts of armed and violent robbery earning him a 10-year prison sentence.
Hugo had a rough stint in prison, with his drug habits routinely sending him to a hospital in Valparaíso and often had extra security and shackles because he once tried escaping during a transfer. In 1992, he suddenly had a mental health crisis and was admitted to a mental hospital for 25 days. In 1995 he was granted parole but was sent back to prison 8 months later after violating it. He was finally released after serving his sentence in 1999. After serving his sentence he again attempted to turn his life around, getting a job painting and repairing cars and saving enough money to open his own store. He also took an interest in yoga and spiritualism. At a yoga class, we would meet 49-year-old kindergarten teacher Verónica Vásquez Puebla (born in 1955) who had a son named Eugenio Honorato Vásquez.
Verónica Vásquez Puebla and Eugenio Honorato Vásquez
Unlike Hugo's prior relationships, this one actually appeared to be promising. Eventually, Hugo asked Verónica for money for "home improvement" and initially she wouldn't hesitate to give her money away. Tragically, Hugo would begin squandering the relationship and would become abusive and temperamental. So on January 8, 2005, he came to ask for money, money that he had never paid back any time prior, Verónica finally said no having now wanted nothing to do with him.
When met with this reply, Hugo was left enraged. In his fit of rage, he grabbed a baseball bat and struck Verónica with it before strangling her. All the commotion had woken up 9-year-old Eugenio after being witnessed, Hugo set his sights on the child and began strangling him as well. Now that both were unconscious, he shoved a cloth down Verónica's throat, tied her hands and feet together and slit her throat. Afterward, he finished them by wrapping their heads in plastic wrap and tying a plastic bag around their heads. He then got a metal drum and hit their bodies repeatibly with a cane and breaking their bones so he could better fit Verónica and Eugenio's corpses inside. Then to hide the smell of decomposition, filled the drum with water, line and plaster before sealing it. He then proceeded to ransack Verónica's house to look for the money he had asked for and left once he found it.
He left the barrel in Verónica's home for a few days and blew her money on his old habits, that being drugs, drinking and prostitutes. Eventually, despite his methods to mask the odour, the bodies inside the drum began to smell. To deal with this, he bought a house with a patio and transferred the barrel to that property. He then asked his father if he could help him dig a hole in his yard. The hole was two meters deep and one meter wide. He asked the movers, moving in his furniture to help move the drum to the back of his house. Hugo was almost caught right then and there because liquid began leaking from the barrel but Hugo said that he worked in the food (specifically French Fry) industry and that it was a chemical from making the product. After everyone left, he buried the drum in the hole he had his father dig. Verónica's brother noticed she was missing and called her only to be answered by Hugo and said that she had gone on a spiritual retreat. Eventually, he and her family went looking for her and found her identification documents in a ditch. Hugo was again called and simply said she was bored with Verónica and hung up.
On January 26, Hugo's new neighbours called the police to report the smell and when they arrived, despite how confident Hugo was that he'd get away with it, and despite all the work he put into hiding his crime, he confessed immediately. The police placed Hugo under arrest while they excavated his yard and recovered the drum and the bodies. Tragically, the news broke at the same time as Hugo's daughter began making plans to reconnect with him. This murder gained Hugo the moniker of "The Drum Psychopath"

Hugo spent his first few months in a mental hospital where he boasted to the doctors about his economic situation and martial arts talent. Hugo's trial took place in November 2005 held by The Guarantee Court of Villa Alemana, and he was handed down a sentence of 27 years imprisonment with his release date set for January 26, 2032. Hugo would now be one of Chile's most infamous criminals and was the subject of an episode of "Mea Culpa"
Hugo being brought to court
Hugo was even given interviews while in prison, in one of these interviews he was asked if he would ever kill again if released and he would tell the interviewer that he didn't know because "I am not the master of destiny". He also told the interviewer that he was triggered by a whistling sound in his ear and he said that it was like watching a movie while he was killing Verónica and Eugenio.
On April 29, 2016, Hugo was put before a parole board and even though Hugo publically said to an interviewer that he was uncertain about whether he'd kill again or not, and even though the prison itself told the judges in charge of the parole hearings not to release him, they outraged all of Chile by granting him parole regardless on the basis of him serving 10 years, learning an actual skill he would use at a job while in prison and good behaviour meaning, legally, they had no reason to deny parole and he was released amongst 788 others. Hugo was despised by all the locals he was now living with, no employer would hire him for any more than a day so he mostly worked odd jobs. Even those who reluctantly admitted that Hugo was nice, added that he still seemed odd and one of his neighbours said "When he looked at you, it felt like he was undressing you with his eyes"
Neighbours would even put up flyers all across the area warning residents about Hugo and to make it clear to Hugo that he wasn't welcome. Parents even refused to let their children go outside alone now that Hugo was back and living alongside them and women wanted to be driven to work and driven home from work instead of walking. Even the mayor of Villa Alemana had ordered an extra police presence in the neighbourhood he moved into.
As soon as she finished reading up on his lengthy and disturbing history, Ámbar was left horrified. Denisse had had 4 partners, one sexually assaulted Ámbar when she was 8, the other was a blatant pedophile who would stare and watch her shower and now her newest one was a man who killed his girlfriend and her 9-year-old child. The only one of Denisse's partners that she actually treated with disdain and contempt was Ámbar's father who cared for and had her best interests in mind. Ámbar explained this all to Denisse who got mad at her daughter and started another fight since she saw Ámbar as judging her newest boyfriend without getting a chance to meet and know him. She even told her that everyone deserves a second chance despite barely knowing Hugo herself at this point.
Seeing as her mother remained stubborn, Ámbar went behind her back and wrote a complaint letter to the apartment's manager requesting that Hugo be banned from the premises. This complaint found its way to the public and soon the other residents of the apartment learnt that Hugo was living with them and essentially, they all came together to demand that they all leave and take Hugo with them. Leave they did but Denisse took Ámbar's brother and moved into Hugo's own home. But Denisse, now on the verge of hating Ámbar for not accepting her relationship with Hugo, punished her by abandoning her underaged daughter and having her live alone in the apartment with a very minuscule amount of money.
After only a week, Ámbar would have to leave the apartment and would go back and forth between staying at various different friend's houses but none were able to let her move in full-time. And she couldn't move into her father's place because he lived in Northern Chile and that would involve abandoning her brother and mother with Hugo. In December 2019, Ámbar moved in to live with Manuel's daughter who was old enough to have her own children and for Ámbar to refer to her as an "aunt". She was described as a much better mother figure than Ámbar's own mother and she was completely ignorant to Manuel's crimes so Ámbar felt safe around her and didn't hold her father's actions against her. And by this point, Denisse disowned Ámbar in all but name. She ended up having to repeat a grade and the school and teachers took note of this and tried to call Denisse 6 separate times for a parent-teacher conference only for her to get aggressive toward the teachers for even calling her at all.
The only interactions she would have with Denisse would be when child support was sent and Ámbar still all these years later had to go to Denisse's house to collect the money in person before her mother spent it all herself. And often she wouldn't even go inside, she'd just knock on the door, Denisse would give her the money without saying a word and close the door. And even if she didn't behave that way, Ámbar steadfastly refused to ever step foot inside Hugo's home. The latest payment was sent on July 29, 2020, when Ámbar told her "aunt" that she was going to head over. After three hours had passed Ámbar had yet to return home from Denisse's and wouldn't answer her phone her respond to any messages. Her Aunt actually called Denisse who blatantly didn't care about her daughter's disappearance and actually hung up the phone. Afterwards, the police were finally called.
Both the police and the entire neighbourhood dismissed the possibility of a runaway and together with the police, the entire neighbourhood began a search effort for Ámbar. Ulises also heard of what had been going on in Ámbar's life as well as her disappearance and immediately travelled to Villa Alemana to join in on the search and of course call and confront Denisse who would never answer or respond. Even when the police themselves showed up, Denisse refused to cooperate or help and ignored even those tasked with finding her daughter. Some witnesses even said that she just stood on her porch and drank a beer with Hugo while others tried finding her daughter
The police would put several flyers all across the local area appealing for information, questioned every neighbour they could find, and together with the Red Cross, firefighters and local volunteers searched the nearby grasslands, bushes, forests, mountains and so on utilizing sniffer dogs, drones and even thermal imaging cameras with the searches continuing into the night. A witness would also come forward and say that in the morning he drove by Ámbar and saw her crying as she walked away. One of Denisse's neighbours also said that in an unusual course of events, Ámbar actually entered Denisse and Hugo's home instead of waiting outside and that she didn't leave. This statement was supported by a CCTV camera showing her walking toward their house but never walking away.
Ámbar's missing notice
This time, simply ignoring them wouldn't work. On July 31, A large group of neighbours went to Hugo's house and waited for him to come outside so they could all gang up on and confront him and some wouldn't even let him go back inside. Hugo acted strangely amicable this time and even invited them to come inside and said the police could even bring in search dogs. Hugo even confidently stated, "If I had a body in here it would smell, Don't you think a body that's been here for 2 days would smell". This statement had the opposite effect of what Hugo had intended since as of now, most people thought Ámbar may still be alive.
Since he gave consent, everyone agreed and entered his home on August 3, including police with search dogs and although no human remains were found, they did find clothing with traces of human blood which were seized to be analyzed by forensics. The blood would end up being a red herring as it was old and belonged to Denisse. Even though Hugo seemed to have been in the clear for now, having just invited police onto his property and them finding nothing, he decided to, on August 3, with Denisse, leave Ámbar's brother in the care of one of his sisters and then the two would just flee and leave the area without notice. By now the search expanded to find them, as suspects to be arrested.
On August 6, photos were uploaded on social media showing Hugo and Denisse at a camp ground in Lilu Lilu trying to find someplace to hide, police also pulled CCTV footage from a store near the camping ground and saw the two buying clothes, hats and sunglasses in an attempt to hide their appearance. The police searched the nearby woods and found the two relatively easily and began interrogating them separately.
Hugo and Denisse at the campground
Denisse who clearly had no concern for her daughter's safety and disowned her over not accepting Hugo, turned on him very easily. She confessed that Hugo had murdered Ámbar and that she knew he did but was too afraid to come forward as Hugo had threatened her, her son and her parents and that he forced her to run away with him. According to her, Hugo had dug and torn up his living room floor to make a 6-foot ditch, bury her in it and refill the living room. The police believed Denisse and figured she'd be a valuable witness so they released her. Hugo exercised his right to remain silent and told the police nothing.
It was fortunate for the police that Hugo didn't need to speak. They checked his cell phone and found that from July 20-July 28 he had searched the following terms "Price of electric weapons, Ranged stun gun, Using chloroform to sleep, Sale of straightjacket psychiatry, Chinese bamboo torture, Chinese water drop torture, Ether sleeping spray, Using ether to put people to sleep, Medical use of scopolamine, Where to buy hydroxybutyric, Total and absolute power, How to change your first and last name, Psychological torture, Torture methods, Meat grinder price, Blows to faint, sleep or immobilize," and so much more which clearly showed that not only did Hugo premeditate Ámbar's murder, but that the murder was likely horrific. Inside his backpack were two knives, a hatchet, rope and a receipt for paint and paraffin wax.
The police easily obtained a warrant to search Hugo's home that same day. They broke up the floorboards in his living room and dug up the soil underneath. There they found three plastic coolers upside down and wrapped into plastic bags. The police removed the bags and opened up the coolers, there they found the decomposed, eviscerated and partially skeletal remains of a young girl, dismembered into 15 separate pieces. The remains were easily identified as Ámbar's based on her clothing. The autopsy revealed that Ámbar had been attacked and suffered numerous blunt force injuries across her body but especially to her hands, arms, forearms, buttocks and thighs. a cloth was stuffed down her mouth as seen with her head, and there were signs on the remains that she had been violently raped. According to the medical examiner, a saw and knife were used for the dismemberment

Police and forensics
Meanwhile, the police faced backlash for releasing Denisse and not investigating her further, many did not believe her to be as innocent and a victim of Hugo as she portrayed, her prior history and actions during the search made that hard to believe. And even after her daughter's dismembered body was found under her living room, Denisse wasn't sad, mourning or even. After several threats including her apartment being vandalized as she was led home under her police guard and threats over the phone, Denisse was sent to a psychiatric institute after attempting to take her own life. The backlash continued after it was revealed that the institute was being kept anonymous as a "witness protection" situation.
And speaking of outage, outrage toward the Chilean government and judiciary was immense as Hugo's release led to Ámbar's death. The families of Verónica and Eugenio were also furious that their killer got to go free to kill again instead of serving his sentence. The outrage was in fact so intense, that the judge who approved Hugo's release was even suspended and investigated for misconduct. Eventually, though, she was reinstated with no consequences because although the law was flawed, she was doing her job as a judge by following it. Instead, Chile changed their laws to make the parole process much more thorough and over all harder to have parole answered as opposed to the rubber stamp process it was before.
On September 24, Denisse was removed from Witness Protection and instead placed under arrest with now the police labelling her a murderer instead of a witness. The police ended up going through Hugo's entire phone history, Denisse's, and CCTV footage around the area before and immediately after the murder which showed that Denisse was an active participant. Denisse's motive was simple yet heartbreaking and horrifying. She had on some level wanted to do this ever since their neighbours forced them to leave their apartment because of Hugo, she and Hugo both said that Ámbar wasn't letting them live together as a romantic couple in peace and she saw Ámbar as coming in between him and Hugo and that as long as her daughter was alive, she would never be with the man she wanted.
Denisse's arrest
While in prison, she was the most hated inmate by her fellow inmates and her own cellmate said that she would "make life impossible" and went out of her way to stay up late just to make sure that she could keep Denisse awake and not let her sleep. This led to Denisse being moved to solitary confinement after a "lynching" attempt. A move that infuriated the public and her fellow inmates. It also upset Hugo who was said to have been begging the courts to let him visit Denisse.
Denisse and Hugo were both tried together with the trial beginning on October 26, 2021, at The Oral Criminal Court of Viña del Mar. During the trial which was held over video link due to COVID-19. Denisse somehow found a way to play Ámbar's favorite music which the court and her relatives saw as a provocation. with the prosecution calling over 54 witnesses, 113 relevant documents, 30 expert reports, and the prosecution presented strong DNA evidence, Psychiatric reports showing them to both be sane, and biochemical reports. According to the prosecution, this is what happened.
Hugo and Denisse during the trial
On July 29, 2020, Ámbar was called by Denisse to pick up the money sent by Ulises. Before Ámbar arrived her now 14-year-old brother was sent to school to pick something up so that he couldn't be a witness to the crime. When Ámbar arrived, Denisse refused to go outside, meet her and hand her the money like always, instead, she insisted and demanded that she enter the home if she wanted it. Somehow, she did convince her and Ámbar went inside where she was immediately attacked by her mother and Hugo with Hugo proceeding to rape Ámbar.
Soon a problem in their plan emerged when Ámbar's brother returned home much quicker than Denisse had expected him to. When Denisse saw her through the windows she hurriedly ran outside and told him that they needed to go to their old apartment because they had gotten a call that someone was breaking in. He couldn't see anything that was going on and really needed to use the bathroom, but his mother insisted that they had to leave now and when he moved past Denisse to use the bathroom, Hugo from the inside kept pushing the door shut so he couldn't enter, something he found odd. He was only allowed in after Hugo dragged his sister's body to another room and closed the door. When he was finally let in to use the bathroom, he heard a loud thumping noise coming from the other room. He left the bathroom and didn't even ask about the noises but Hugo felt the need to frantically explain them away and say it was his mother coming over for a visit and folding clothes. Ámbar's brother was one of the prosecution's star witnesses.
Hugo, now left alone, began dismembering Ámbar into the aforementioned 15 pieces and placed them into the coolers while CCTV cameras showed Denisse and her son at a metro station on the way to their apartment. Denisse showed no reaction to helping her boyfriend rape and murder her daughter. While at the metro station, she sent the following text messages to Hugo. "I'm more calm now, I love you, kisses", "I hope everything goes well for you", "See you tomorrow" and "Good night love" That second message was her wishing Hugo luck in disposing of her daughter's body. They also exchanged 14 phone calls. When they arrived at the apartment, Denisse had her son stay there while she rushed to a store to purchase paint and paraffin wax. Denisse was caught on CCTV doing this and the cashier was called to testify. To keep him away from their home, Denisse had her son stay at the apartment alone for the night as she returned.
Hugo and Denisse then went to the living room to remove the wooden floorboards in the living room, dig a six-foot hole through the soil underneath the floor, dumped the coolers into the hole, filled the hole back in, and placed new replacement floorboards where the old ones were and nailed them back to the floor sealing up the makeshift grave. The paraffin wax was used to try and keep any search dogs from detecting the stench of decomposition. Neighbours heard the sound of equipment such as drills and hammers being used but that the sounds were spaced out as if Hugo and Denisse were trying to be quiet with them. Denisse then wrapped Ámbar's cell phone in aluminum foil, burnt it and discarded it in a crawl space. Denisse's fingerprints were pulled from this foil. Denisse's shoes were also examined and traces of wax were found on the soles. Hugo seemed supremely confident that he would never be caught but as soon as he was confronted by his neighbours he was suddenly terrified and frantically told Denisse that they needed to run away.
On November 26, 2021, the two were found guilty and on December 7. both were sentenced to life imprisonment without the possibility of parole until at least 40 years into the sentence meaning the two won't even have the possibility of release until Hugo is at least in his 90s. It wasn't just murder the two were convicted of, they also were sentenced for rape and abuse, tragically not just that of Ámbar. Ámbar's brother wasn't just a major in the murder case, Hugo and Denisse had been sexually abusing him as well this whole time and the two were sent to prison for those crimes. For the sake of his protection, specific details involving his case have thankfully not been made public. They were both acquitted on the charge of illegally burying a body and Denisse was acquitted on the charge of raping Ámbar. They both appealed the verdict and sentence but on June 2, 2022, the Chilean Supreme Court upheld the decision.
Now I mentioned that Manuel García Queirolo would be brought up again as his actions were even more heinous, Well, during her disappearance and murder, the Cyber Crime Unit was investigating Manuel for completely unrelated reasons, he was suspected of producing and possessing child pornography on his cell phone and other sex crimes from 2016-2020. On August 17, 2020, he was placed under arrest while investigators went through his phone. As they expected, he did possess mutable inappropriate images of minors.
Manuel's arrest
Horrifyingly enough, 400 of which were all of Ámbar back when she lived in his property. Aside from photographing her while she was showering, he also had pictures of upskirts and pictures taken up her dresses and the phone camera zoomed in to focus on her privates. Ámbar never found out about these images. On December 15, 2021, Manuel was convicted by The Oral Criminal Trial Court of Viña del Mar and sentenced to 14 years imprisonment on December 27.
Ámbar's other relatives, friends and various women's rights organizations were satisfied with the verdict and even celebrated in the streets. The families of Verónica and Eugenio were also pleased to know that he was back in prison. For Hugo and Denisse, they are likely to never see each other face to face ever again. Ironically, that is despite being in the same prison. On April 27, 2022, Denisse was transferred to the same prison as Hugo after an apparent "lynching" attempt which led to lacerations on the scalp, bruises on both sides of the neck, an orbital hematoma, a laceration in the right eye, a wound on the lower lip, a hematoma in the lumbar dorsal area and on the left elbow. Although she has been attacked several times before this was the most brutal one.
Ámbar's brother is now 17-18 and is living with other family on Ulises's side. He is said to be doing well, has made several new friends and has moved on and put this incident behind him with his life looking up for him.

This is the result of four generations of design trying to max out my printer.
8 years ago I paid $800 for a small delta kit with no instructions and almost threw it in the dumpster after wrestling with all the technology and no docs or guidance except help on the web. That was my first 3D printer, had not ever touched one before so I was pretty green.
Anyway, once I got it working, my first thought was..."too small!". So I started designing (in Solidworks) a larger scale version with improvements. 4 generations later I had bought and learned to use a CNC mill so that I could machine totally custom parts (in my dining room, so I also had to design a sound-and-spray-proof enclosure and then a custom large table for that, then a super-quiet air-compressor, and...yeah, it got kind of ridiculous. But a sweet setup. I could run CNC jobs at 11pm without bothering the apartment below me. Stealth prototyping! I sold the whole setup for $4K to somebody ELSE living in an apartment. 3D CNC design and machining is a LOT of work and it was taking up half of my dining room.)
YEAH, THIS WAS A *SIDE PROJECT* FOR MAKING A MORE CUSTOM PRINTER

---BACK TO THE PRINTER---
My design goal was to make it big, fast, accurate, and print anything. Also wanted multi-filaments. I was less interested in turn-key reliability and automated functions like filament detectors.
It's not as fast as I wanted; I underestimated the stiffness required when trying to balance weight vs strength, mostly in the machined vertical stages, which I believe are warping under hard moves. I got too hung up on saving weight! This version, despite adding a second extruder, was almost half the weight of the ponderous V3.

---THE FRAME---
Robotdigg parts using 20x40 upright extrusions and 20x80 extrusions for the base
---THE BED---
Multi-layer metal bed. Main bed is 1/4" MIC6 aluminum (cut with a water-jet!). MIC6 has low internal-stress so it doesn't warp when heated. The other two thinner layers were added later to sandwich in the bed temp sensor and a layer to hold the magnets.
500W 120VAC silicone heater underneath. Bed has no problem hitting 100C.

---PRINT SURFACE---
Flexible spring-steel sheets with two registrations holes for the pins sticking up from the main bed.
The sheets have different surfaces for different materials, especially a Garolite surface for nylon. Nylon both warps bad AND grips so well that one larger print would curl up and pull up the sheet with it! I made a second version with a thicker plate to solve that problem.
My main surface for PLA uses an adhesive film of PET. Since I don't trust a surface to stick well for printing AND pop off easily, I just always use cheap hairspray. Sticks really well and easy to clean off when it starts to build up too much. I now get nostalgic for 3D printing whenever I smell grandma's hair.

---VERTICAL STAGES---
These are the main reason I bought a CNC mill. I designed them to be as light as possible and especially to accommodate the spring-clamped effector rods. Belts should be easy to pop off if needed. Polycarbonate wheels for stiffness. Most parts are from OpenBuilds store.
BTW, ALL the big screws on moving parts are aircraft-grade aluminum.
I went through most of the main rod-joint designs: Traxxis captured-joints, magnets-ball-ends, but I came back to the spring design once I tried the others. Easy to remove, shock-absorbent, light, no slop. My biggest issue with the magnets was the weight. 12 sets of magnets are heavy and I had thicker rods with those too. Otherwise they worked great and perfect. The difference between a magnet and a spring is that a spring gets stronger as you pull away so it will try to pull back in. whereas a magnet gets weaker when pulled away. The result is that magnet-held rods will print perfectly with no errors, right until they pop off from too hard a move and ruin the entire print job. The springs however can actually temporarily pull away under a hard force, causing a slight position error, but they WON'T pop off. I'd rather have poor prints than ruined ones.
Also, the belts. I wanted to put stiffer ceramic-reinforced belts but discovered (after I bought them) that they can't bend around a typical 10mm pulley and bigger pulleys won't fit into my design.

The dreadful looking box on the left was my attempt to make a control interface but it never got very far...one button to cycle through of list of things that can be adjusted by the knob. Mostly I just used it set the brightness of the main effector lights.

---THE EFFECTOR---
The effector stage platform went through numerous iterations and the final one is visible here. The rods are connected to the triangular frame but a quick-release plate holds everything else and only requires loosening 9 screws then twist-and-lift to remove it. I hate removing screws and this allows me to completely remove everything if I want to convert the stage to something else.

A number of 'innovations' were attempted with the effector, some effective, others...not so much :/
-'Use forced air instead of fans to reduce clutter, weight, and provide more intimate targeting of the print close to the nozzle' This failed: I could not find an air-pump that could push enough air through the air-lines to the effector. High flow-resistance through the tubing requires a very high-pressure air-pump with decent through-put. The pumps would need to be way too big and noisy so I had to settle for the two fans in the picture.
This shows the full blower assembly that was designed into the existing effector stage. Air flows down from one connection, splits down each leg and extrudes from a ring of tiny nozzles surrounding each extruder nozzle. The height can be adjusted to accommodate different extruder block and nozzle sizes (sliding o-ring seals).

This shows the two halves of the air-nozzle array I machined with a *tiny* ball endmill. The assembly snapped together is 2mm thick. It was a work of art...what a waste! The first time I snapped them together it was like they were, er, machined!
2mm thick fiberglass halves that snap together and hover right underneath the heat blocks.
-'Use water cooling instead of fans to again reduce clutter and noise' (this works well but I'm not sure that in the long run it was really a benefit given the complexities. Water is WAY better coolant than forced air, and so far leaks have not been an issue, for some time now. Leaks are the bane of every fluidic design!)
Here is the external pump assembly: A CPU water-cooler with a radiator and fan. The large empty bay was designed to 'sling' a large air-pump that turned out to still be too weak.

-'Probe the bed using the nozzle itself' Other methods had too many issues, especially with a larger machine, and delta printers calibration tolerances allow the effector platform to tilt, displacing the nozzle. So a separate detector or touch-switch may not match the nozzle itself. The solution was to build some piezo sensors under the extruder bodies to detect when the nozzle presses down. They are just the cheapo piezo-buzzers you can get for hobby electronics, cut-able with scissors. I have one piezo sensor under each extruder and they are cross-wired so that side-ways forces will be rejected. I built a tiny inline custom module to provide a digital output. This has been working very well! Moving the effector stage too hard can cause false triggers though, and because the voltage on a piezo will fade away quickly, you can't probe TOO slowly. I got it dialed in though and routinely probe 400 points across my bed for mesh-bed leveling'.
-'Dual extruders with (fairly) easy-to-swap heat-blocks such as between a V6 and a Volcano'. They work. I designed the water jackets to use the E3D's Chimera-style smooth heat-breaks so that I can pull them out easily, or precisely level the two nozzles together. I still had the hassle of the wiring but RC power connectors worked well (the ones like a thin brass cylinder no bigger than the wires themselves)

The extruders themselves are Zesty Nimbles. They are classified as 'remote direct-drive', meaning the grip on the filament is very close to the nozzle tip but the motor is far away; very important for flexible filaments and overall precision of the extrusions. Normally that means the extruder motor would have to be right above the nozzle. Fine for cartesian printers, awful for a light moving delta head. The Nimbles use a motor mounted on the printer frame that turns a drive cable connected to the hot-extruder gear that grips the filament. You can see them flaring out from the sides (in the main pic) attempting to balance the torques created on the effector stage by the weight and stiffness of the drive cables.
Anyway, they have their issues but the only workable solution for me.

---MY HELP---
Squeek is good at finding things I drop
https://preview.redd.it/8rv04b5v754d1.jpg?width=2880&format=pjpg&auto=webp&s=7042092c4809fa23f4bb671b736ca4f721f82daa
---CALIBRATION---
I would never build another delta. The advantages from the early days were short lived and I've learned that print speed tends to be limited by the filament itself and not how fast the head can move. The extruder can only push so much through before it starts to skip. Also, you can't really 'square-up' a triangle, so all the methods for measuring how square a joint is are worthless. Plus dimensional errors in the rod joints, 12 of them, stack up in too complex ways to easily wrangle.
Ultimately, by giving the frame some quick grunts warping it in just the right way, got things to about .25mm flatness and with mesh-bed leveling I can pretty much print a .1mm layer across the entire print space.
---FINALLY, THE PERFORMANCE---
I can print any filament, including the softest ones out there, with the right bed surface and easy to pop off when done.
I printed these (working) 4mm gears using a .15mm nozzle.

This is a test print of my maximum printing volume. So this passes the 'Can it make an Iron-Man helmet?' test.

TPU-Phone Case.
I don't know why promoters like to say things like 'make your own phone case!'. This was probably the most difficult print I've ever done. I needed the 2nd extruder for dissolvable filament and had to precisely mock up the phone to make sure the fit was not too tight or too loose. Lots of iterated sub-prints to dial in the dimensions just right. It has air pockets throughout the volume, especially the corners. And no more losing my black phone in the car!
However, TPU collects dirt easily so it starts off looking like this glowing green but then gets grimier and NOTHING will clean it up.

And finally, wear gloves! This is what can happen slinging a long 1x2 pine strip. It didn't hurt at all and I had fun waving it at my co-workers and saying "What should I do about this?"
