Stepfather Executed After Killing Three Children, Claimed Demons Controlled Them…NO MERCY….
Stepfather Executed After Killing Three Children, Claimed Demons Controlled Them…NO MERCY….

A crime that shocked the city and remains one of the most notorious cases in its history. For many people, the story ends there. But it doesn’t. Before his name became associated with one of Texas’s most tragic criminal cases, Rubio was trying to build a family. Two of the children weren’t biologically his, yet he chose to raise them as his own.
At one point, after the children were temporarily removed from the home, he found work and met the conditions for them to return. So, how does someone go from fighting to reunite a family to spending more than 20 years on death row? That question would take investigators, mental health experts, prosecutors, and two separate juries years to unravel.
Before we go back to Brownsville, Texas, let me know where you’re watching from today. It’s always fascinating to see viewers joining us from all over the world. To understand how this case reached that point, we have to go back to Brownsville, Texas, where a chance meeting between two young people set in motion a chain of events neither of them could have imagined.
Angela Kamacho was born in 1979. By the time she met John Alan Rubio, she was already a mother and she was already living inside a relationship marked by violence. Kamacho and Rubio crossed paths sometime around 2000 or 2001. They were living in the same apartment complex in Brownsville, Texas, neighbors before they were anything else.
At the time, Kamacho was in a relationship with a different man, the biological father of her young daughter, Chisa Angela Casada. According to accounts, later entered into the official case record. That relationship had turned physically abusive. It was in the middle of that instability, a young mother, an abusive partner, a small child caught in the middle that Kamacho’s connection with Rubio began.
She eventually ended the relationship with Julisa’s father. Not long afterward, her relationship with John Alan Rubio started. This is a detail worth being precise about because the court record itself is precise about it and because precision matters for understanding what came later. Julysa Casada was not John Alan Rubio’s biological daughter.
Her biological father was the man Kamacho had left behind. What Rubio would become to Julisa was something else entirely. A stepfather in every practical sense. A man who entered a toddler’s life while her mother was already pregnant again, this time by him. Kamacho, at the point she and Rubio became a couple, was navigating exactly the kind of situation that leaves almost no room for stability.
A young single mother recently out of an abusive relationship with a small child depending on her and another pregnancy already underway. That’s the foundation this family would be built on. Not a clean start, but two people trying to construct something new out of circumstances that were already difficult before they even met.
Little in the public record describes Rubio’s own life before he met Kamacho in any real detail. But what does emerge from later court proceedings paints a picture of someone who had his own difficult upbringing, including exposure to abuse in his own childhood, a fact Judge Gonzalez would later acknowledge publicly at Rubio’s second sentencing years after the crime without treating it as an excuse.
That background does not appear anywhere in the earliest parts of this story by coincidence. It’s part of what the defense would eventually try to use to explain, though never to justify how Rubio arrived at the place he did. That’s where the next chapter of this family’s story begins, not with a wedding and not with a plan, but with two people in their early 20s moving in together.
While already carrying the weight of a previous relationship’s fallout, about to take on responsibilities neither of them was fully prepared for. Angela Kamacho moved in with John Alan Rubio while pregnant, bringing Jalisa with her. She soon gave birth to a son. The child’s biological paternity was not entirely clear from the case record.
According to court documents, the boy was possibly not Rubio’s biological son, but Rubio did not treat that uncertainty as a reason to keep his distance. The boy was given Rubio’s surname and became known as Johnny E. Rubio in every practical sense. In the home, in daily life, in the role he occupied, Rubio raised both Julisa and Jon as his own children, regardless of what a paternity test might have shown.
Then, in January 2003, the couple had a child together, Mary Jane Rubio. She was Rubio’s only biological child among the three. Born into a household that was already under considerable strain before she ever arrived. By early 2003, five people were living under one roof in a modest Brownsville apartment. John Alan Rubio, Angela Kamacho, three-year-old Julisa, one-year-old John, and a newborn, Mary Jane.
Two of the three children were not biologically Rubio’s, and yet all three called him dad in the only way that mattered dayto-day. He was the man in the home working to provide for them, present in their lives. It is worth sitting with that fact for a moment because it complicates any attempt to tell this story as a simple one. This was not, at least on the surface, a household defined by rejection or indifference toward children who weren’t biologically his own.
By the record’s own account, Rubio had accepted that role and for a time appeared committed to it, attending to the day-to-day realities of caring for a toddler and an infant, not just the idea of fatherhood. Financially, the household was never far from the edge, even in its better moments. Rubio worked when work was available, typically in low-wage jobs that offered little stability and no real cushion against a bad month.
Kamacho, with three children under the age of four by early 2003, had little practical opportunity to bring in outside income of her own. That meant the entire household survival rested on Rubio’s ability to keep finding and keeping work. a precarious arrangement even before anything went wrong. That effort would not hold.
The pressure on this household was about to become severe. And the first real crack in this family’s foundation had already appeared even before Mary Jane was born. A crisis that would foreshadow in miniature just how fragile everything actually was. Before Mary Jane’s birth, the family had already been through a crisis serious enough to break it apart, at least temporarily.
a warning sign that in hindsight deserves real attention. Rubio had a documented problem with inhalent abuse, specifically the practice of huffing spray paint to get high. It was serious enough that it came to the attention of child welfare authorities. As a direct result, Julisa and Jon were removed from the home and placed into foster care, separated from their mother and the man who was raising them.
For a family already navigating hardship, this was about as low a point as it could get. Two young children taken from their parents because of a father figures substance use. A state agency stepping in to do what the household itself could not guarantee, a safe, stable environment. Texas Child Protective Services, which handled the removal, would have required Rubio to meet a series of conditions before the children could be returned, typically including demonstrating sobriety, securing stable housing, and showing a reliable source
of income. The fact that Julisa and Jon were returned within a matter of months suggests Rubio was able to satisfy at least the basic requirements the agency set for him, even if the underlying stability those requirements were meant to ensure would prove short-lived. But Rubio, according to the record, responded to that crisis by getting his life in order, at least outwardly.
He found steady employment. That effort mattered to the authorities overseeing the case. Roughly 3 to four months after the children were removed, they were returned to Rubio and Kamacho’s custody. For a brief window, it looked like the family had genuinely turned a corner. A father figure had lost his children over his own behavior, changed course, found work, and gotten them back.
It’s important to name what this period represents in the larger story. It shows that Rubio was at least once capable of responding to a serious wakeup call by making concrete changes. That fact does not excuse anything that happened later, but it complicates any version of this story that paints him as someone incapable of care or responsibility from the very beginning.
That window would not stay open long. The job that brought the children home would not last, and its loss would set off a much faster and more dangerous chain of events than the one that came before, one that would end very differently. In December 2002, Rubio lost his job. One month later, in January 2003, Mary Jane was born, a fifth person now depending on a household that had just lost its only source of income.
What followed was a fast grinding collapse, the kind that compounds on itself day by day. Rubio worked odd jobs to try to bring in money. According to the case record, at his lowest point, he also turned to prostituting himself in an attempt to keep the family afloat. None of it was enough to keep pace with what the household needed.
By March 2003, the family could not make rent. The deadline was March 11th, a date that would become, for reasons that had nothing to do with money, the darkest day of this family’s life. Facing eviction, Rubio asked his brother whether the family could move in with him. His brother said no. Rubio’s brother’s girlfriend was separately asked for a loan to help cover the gap. She declined as well.
Somewhere in the middle of this stretch, roughly $175 in cash, money the family badly needed and could not easily replace, was reported stolen from Rubio. On top of the housing crisis, the food stamp benefits the children depended on had been paused, tied up in a paperwork issue that Rubio and Kamacho had no immediate way to resolve.
The safety net that should have caught a family in exactly this situation had a hole in it at precisely the moment they needed it most. And there was no one stepping in to close that gap. On March 10th, 2003, the day before the killings, Rubio and Kamacho reached a decision born out of that mounting desperation. With no money, no available housing, and no support forthcoming from family.
They agreed that the next step would be moving the three children into a homeless shelter. It was, by any reasonable read of the record, a last resort, an acknowledgement that they could no longer provide for their children in their own home. It’s worth pausing here to be direct about something because this documentary is not going to let financial hardship do work it doesn’t deserve to do in this story.
None of what’s been described here, the poverty, the eviction, the hunger, the theft of $175, the paused benefits, the plan to seek shelter, explains or excuses what happened next. Financial collapse does not turn a parent into a killer. Millions of families hit rock bottom every single year, facing eviction and hunger and impossible choices without any of them ending in violence.
Something else entirely was happening inside John Allan Rubio during this same period. Something that had nothing to do with rent checks or food stamp paperwork, and it had been quietly building for longer than anyone around him seemed to fully grasp. It’s also worth noting how compressed this timeline actually was.
in the space of roughly 10 weeks from Rubio’s job loss in December 2002 through Mary Jane’s birth in January through the theft of the $175, the food stamp suspension, the failed attempts to secure housing with relatives, and finally the decision to seek out a homeless shelter, a family that had months earlier successfully reunited after a foster care placement found itself back at the edge of collapse.
The speed of that unraveling matters because it left almost no time for anyone outside the household, extended family, case workers, neighbors to notice the severity of what was happening and intervene before March 11th arrived. Financial ruin was the visible crisis, the one that left a paper trail. Eviction notices, stolen cash, paused benefits.
But according to evidence later presented at trial, there was a second crisis unfolding in the same household at the same time. This one invisible to anyone not paying close attention. A psychological deterioration inside Rubio himself. One that would ultimately come to define the entire legal battle over his fate.
Rubio had a documented history of substance abuse dating back at least to the inhalent use that had already cost him custody of two of the children once before. By the accounts presented in court, that history was intertwined with a psychological state that intensified sharply in the weeks leading up to March 2003.
A period that overlapped almost exactly with the family’s financial collapse. What exactly was happening to him during that stretch is genuinely contested, and this documentary is going to treat it that way rather than pretend there’s a single clean answer available. The defense would later present psychiatric evidence arguing that Rubio was suffering from a serious mental illness, including delusional beliefs disconnected from reality.
The prosecution would argue in response that whatever Rubio was experiencing did not rise to the legal threshold required to excuse him from responsibility, that on some fundamental level, he still understood what he was doing and could be held accountable for it. Two competing explanations, both grounded in the same set of facts, would shape the courtroom for the next 20 years.
What isn’t contested because it comes from Rubio’s and Kamacho’s own later statements to investigators is that in the days before the killings, people around Rubio began to notice something different. Unusual behavior, unusual statements, the early edges of a belief system that would soon take a horrifying and concrete shape inside that apartment.
That belief centered on the idea that something evil tied specifically to his own deceased grandmother had entered his home and his family. There is also the question of sleep, stress, and the compounding effect of everything happening at once. In the final weeks before March 11th, Rubio was by multiple accounts barely sleeping, moving between attempts to find work, dealing with the fallout of the stolen money, and increasingly consumed by his fears about the children.
None of these pressures caused the beliefs that took hold of him, but [clears throat] taken together, they describe a man whose grip on ordinary daily functioning was already loosening well before the crisis reached its breaking point. A warning sign that tragically no outside authority was in a position to see or respond to in time. That belief did not stay abstract for long.
Within days, Rubio would act on it in the most extreme way possible. And the question of whether he genuinely understood the reality of what he was doing when he did, or whether his grip on reality had by that point already broken completely, would occupy Texas courts on and off for the better part of the next two decades. By the evening of March 10th, 2003, the Rubio household had reached a breaking point.
Months of financial hardship, uncertainty, and Rubio’s increasingly disturbing beliefs had created an atmosphere unlike anything the family had experienced before. What happened over the next several hours would forever change the lives of everyone connected to them. According to court records and the statements later given by John Alan Rubio and Angela Kamacho, the violence began with three-year-old Julisa Casada.
Rubio later claimed he had become convinced she was no longer herself and believed she was under the influence of an evil spirit. Acting on that belief, he took her life. The tragedy did not end there. As the night continued, one-year-old Johnny E. Rubio and two-month-old Mary Jane Rubio also lost their lives.
Investigators later concluded that all three children had been killed inside the apartment they shared with Rubio and Kamacho. The investigation would later reveal another deeply disturbing fact. After the children died, Rubio admitted that he separated their heads from their bodies. During questioning, he claimed he believed he needed to do so because in his mind, the children remained under the control of evil forces.
Those statements would become one of the most significant pieces of evidence examined during the legal battle over his mental state. When daylight arrived on March 11th, the apartment appeared quiet from the outside. Nothing suggested that only hours earlier, one of Brownsville’s most devastating crimes had unfolded inside.
Later that day, Rubio’s brother arrived at the apartment. Once he realized what had happened, he immediately sought help, flagging down a passing police officer. Officers entered the residence and quickly secured the scene before detectives from the Brownsville Police Department and crime scene investigators began documenting the evidence.
Rubio and Kamacho were taken into custody without incident and questioned separately. During those interviews, both provided investigators with accounts of the events while detectives worked to compare their statements against the physical evidence collected from the apartment. Medical examiners later conducted autopsies on all three children while investigators carefully processed the scene, photographed evidence, and reconstructed the sequence of events.
By the end of the investigation, authorities believed they had established a clear timeline of what had taken place inside the apartment during the night of March 10th and the early morning hours of March 11th. The investigation answered many questions about what had happened inside the apartment. But it also raised another question, one that would ultimately become the center of two capital murder trials.
Did John Alan Rubio understand the reality of his actions that night? Or had his grip on reality become so severely distorted that he no longer understood what he was doing? That question would dominate every courtroom proceeding that followed. In the hours and days after his arrest, John Alan Rubio gave investigators an explanation for what had happened.
According to his own statements, he believed the children had been possessed. He said his three-year-old stepdaughter, Julisa, had been taken over by the spirit of his late grandmother. A belief he said was confirmed in his mind by the way she was speaking and behaving in the hours before her death. He said his infant daughter, Mary Jane, had laughed at him in a way that convinced him she too had become possessed and was no longer simply an innocent baby.
Angela Kamacho’s account, given separately to investigators, filled in more of the picture, and it reveals just how far removed from ordinary reality this family’s final days had reportedly become. According to Kamacho’s own statement, Rubio came to believe that one-year-old Jon had been possessed after a stranger on a public bus handed the boy a piece of candy the day before the killings.
An entirely mundane moment that, in Rubio’s mind became something sinister. Kamacho herself said she became convinced something was wrong with Jon after Rubio performed a folk ritual inside their home. Cracking an egg into a glass of water and reading the way the yolk floated as a sign that the boy had been cursed. It bears repeating clearly.
These are Rubio’s and Kamacho’s own claims offered to investigators after the fact, not independently established facts about what was actually happening in that apartment in an objective sense. But as statements, they became absolutely central to the legal case that followed because they raised a question the Texas courts could not avoid answering.
If a man genuinely believed the things he told investigators he believed, however irrational those beliefs were, was he still legally responsible in the eyes of the law for what he did to three children under his care? That question would not be settled quickly, and it would not be settled cleanly. It would take the state of Texas two full trials spanning seven years to reach an answer that could survive the appeals process.
And [clears throat] even then, as later chapters will show, the answer would remain contested for nearly two more decades after that. It is also worth noting how these statements were received publicly at the time. When details of Rubio’s account first became known, they turned an already devastating local crime into a case that drew national attention.
The specific nature of his claims, possession, evil spirits, a ritual involving an egg and a glass of water made the case difficult for outside observers to categorize. Was this a story about a violent criminal using a bizarre excuse or a story about a man in the grip of genuine severe psychosis? That tension between two very different readings of the same set of statements is precisely what made the insanity question once it reached a courtroom so difficult to resolve.
Rubio was the first of the two defendants to stand trial. Jury selection began in September 2003 and the trial itself proceeded through October of that year, unfolding in a Cameron County courtroom that would become intimately familiar with this case over the following 20 years. Prosecutors built their case around establishing precisely what had happened inside the apartment and Rubio’s direct role in it, arguing that regardless of whatever he claimed to have believed at the time, he understood the fundamental nature and consequences
of his actions and should be held fully accountable under the law exactly as any other defendant would be. Rubio’s defense took a fundamentally different approach, not disputing that his actions had caused the children’s deaths, since that much was not seriously in question, but arguing instead that he was legally insane at the time of the killings.
The defense’s position was that his break from reality was severe enough that Texas law should not hold him criminally responsible in the same way it would hold a person of sound mind who had committed the same acts. This is where a distinction matters enormously, and it’s a distinction the courts themselves had to work through with real care over the following years.
Believing something false, even something as extreme as demonic possession, is not automatically the same thing as meeting the legal definition of insanity. Under Texas law, an insanity defense requires demonstrating that a defendant, because of a severe mental illness, did not know that what he was doing was wrong at the time he did it.
Simply having delusions, however disturbing, is not by itself sufficient to meet that bar. The defense had to convince a jury that Rubio’s mental state, specifically at the moment of the killings, met that precise and demanding legal standard, not just that something was seriously wrong with him. The jury did not accept that argument.
On November 7th, 2003, Rubio was convicted of capital murder on all three counts. The following day, all 12 jurors voted unanimously to sentence him to death, and state district judge Robert Garza formally handed down that sentence. Before the sentence was entered, Rubio reportedly told the court that he wanted to be executed, a statement the prosecution would later site as evidence he understood exactly the gravity of what he had done.
The trial itself was not simply a formality. Both sides called mental health experts to testify, and their conclusions did not align. Experts called by the defense described a man who had by the time of the killings lost touch with objective reality in a way consistent with a serious psychotic episode. Experts called by the prosecution disputed the severity of that assessment or disputed that whatever break Rubio experienced actually prevented him from distinguishing right from wrong in the specific narrow legal sense the insanity
standard demands. The jury’s job was not to decide whether Rubio was disturbed. Few people in the courtroom seriously argued he wasn’t, but to decide whether he met that precise legal bar. They decided he did not. The trial also drew intense local and national media coverage. With reporters filling the Cameron County courtroom for much of its several week run for a border city not accustomed to that level of outside attention.
The scrutiny added its own pressure to an already difficult process. One that Brownsville residents, jurors, and court officials alike would have to navigate a second time 7 years later when the case returned for retrial. For a moment in the fall of 2003, it looked like this case was fully resolved. It was not. Rubio’s death sentence would not ultimately survive the appeals process that followed.
Not because any court found him innocent of the killings, but because of a legal error made during the trial itself, one that would eventually send this entire case back to square one and force Texas to prosecute it all over again. Years later in front of an entirely new jury, years passed.
Rubio sat on death row, his case moving slowly through the appellet system in the background. And then on September 12th, 2007, the Texas Court of Criminal Appeals overturned his conviction and death sentence entirely by a narrow, sharply divided 5 to4 vote. The ruling had nothing to do with Rubio’s guilt or innocence in a factual sense.
It hinged instead on a constitutional issue rooted in the original trials procedure. Statements Angela Kamacho had made to investigators were used as evidence against Rubio during his 2003 trial, but Kamacho herself never testified in person and was therefore never cross-examined by Rubio’s own defense team. The appellet court found that this violated Rubio’s constitutional right to confront the witnesses testifying against him, a foundational protection in American criminal law.
Because of that violation, the conviction could not be allowed to stand, and a new trial was ordered from scratch. It’s worth being completely direct about what this ruling did and did not mean because it is easy to misread. It did not mean Rubio was found innocent. It did not mean the appellet court doubted in any way what had actually happened to the three children in March 2003.
It meant specifically and only that the legal process used to convict him the first time contained a flaw serious enough that Texas law required the entire trial to happen again. This time without that particular constitutional defect. Rubio’s retrial was pushed back repeatedly and eventually took place years later than originally anticipated.
Initial plans had it starting as early as the fall of 2008, but pre-trial motions, competency questions, and scheduling delays pushed the actual retrial back nearly two more years. In June 2010, a new jury was seated in a different Cameron County courtroom, hearing much of the same evidence a second time, including much of the same expert testimony on Rubio’s mental state that had shaped the first trial 7 years earlier.
On July 26th, 2010, that second jury reached the exact same verdict the first one had. Guilty of capital murder on all three counts. Three days later, on July 29th, 2010, Rubio was sentenced to death for the second time in his life. State District Judge Noe Gonzalez addressed him directly at that second sentencing, telling him, “If you want forgiveness, you’re going to have to get it from a much higher source.
” A Cameron County assistant district attorney involved in the case separately remarked that there was a special place reserved in hell for what Rubio had done, expressing the prosecution’s clear agreement with the jury’s decision. Judge Gonzalez, who by his own account had sentenced more people to death than any other judge in South Texas at the time, also acknowledged publicly that he recognized Rubio’s own troubled and abusive childhood without treating that history as a justification for the verdict.
7 years after the first jury sent him to death row, a second jury, hearing the case fresh with none of the procedural baggage of the first trial, had independently reached the same conclusion. But the broader case still wasn’t fully finished because Angela Kamacho’s fate had followed an entirely separate track during all of this, and the two codefendants were about to arrive at strikingly different outcomes for their roles in the same three deaths.
Angela Kamacho’s path through the legal system ran on a separate track from Rubio’s almost from the beginning and it would end in a very different place. Before her case could even proceed toward trial, the court first had to determine whether Kamacho was mentally competent to stand trial at all. That process took considerable time.
A competency hearing was scheduled, then delayed, and finally resolved in May 2004 when Kamacho was formally found competent to face the charges against her. At that stage, prosecutors still intended to seek the death penalty against her as well, mirroring their approach with Rubio, and a subsequent state psychiatric evaluation found her legally eligible to face that sentence.
But Kamacho’s case never actually reached a jury for a verdict. On June 29th, 2005, she pleaded guilty to three counts of capital murder as part of a negotiated plea agreement, one that formally removed the death penalty from consideration in exchange for her guilty plea. She was sentenced to three concurrent life terms with the possibility of parole after 40 years served.
The decision to take the death penalty off the table in Kamacho’s case was not a simple or uncontroversial one. The Cameron County District Attorney at the time publicly described it as one of the most difficult decisions of his entire tenure in office. Part of the pressure behind that decision came from outside the courtroom entirely.
Kamacho held Mexican citizenship and the government of Mexico had signaled clear opposition to a potential death sentence along with the likelihood of an international appeal if one were ultimately imposed on her. Had she been sentenced to death, she would have become the first woman with Mexican citizenship on Texas’s death row, a designation with real diplomatic and legal complications attached to it.
Prosecutors also weighed a more practical reality in reaching the plea deal. pursuing capital punishment against Kamacho could have cost several million additional dollars in prosecution expenses with no guarantee that a death sentence even if secured would ultimately survive the same kind of appellet scrutiny that had already unraveled Rubio’s first conviction.
So two people tried in connection with the deaths of the same three children ended up on two entirely different legal paths. Rubio faced two separate juries, two separate death sentences seven years apart, and as of 2026, a scheduled execution date. Kamacho faced a single negotiated plea agreement and a life sentence with her first realistic opportunity for parole, not arriving until March of 2043.
Three, she remains incarcerated today at the Christina Melton Crane unit in Gatesville, Texas. Though prosecutors have publicly expressed doubt that she will actually be released even once she becomes parole eligible. That divide, one parent facing execution, the other facing eventual, if uncertain, parole eligibility decades from now, is part of what makes this case still resonate in Brownsville more than two decades later.
And it forms the direct backdrop against which the final stretch of Rubio’s own appeals would play out all the way into 2026. It’s a divide that has drawn its own share of public debate over the years. Questions about whether justice was served proportionally between two people convicted in connection with the same three deaths or whether the vastly different outcomes simply reflect the very different legal tools available to prosecutors in each case.
A guilty plea that guarantees a conviction and avoids years of costly appeals versus a trial verdict that remains vulnerable to exactly the kind of reversal Rubio’s first conviction experienced. Neither path is inherently more or less just than the other under the law. They are simply different mechanisms that produced very different results for two people accused of participating in the same crime.
It’s a tension that shows up again and again in capital cases involving codefendants nationwide, not just in Brownsville, and one that this case illustrates with unusual clarity given how directly the two outcomes can be compared. For more than a decade after his 2010 re-sentencing, Rubio’s case moved slowly and repeatedly through the appeal system, each round narrowing his remaining legal options a little further.
His direct appeal against the second death sentence was dismissed by the Texas Court of Criminal Appeals in October 2012. Two additional appeals were denied by that same court in May 2018. A subsequent petition for a rid of habius corpus was denied in January 2022. For a brief period that same year, it genuinely looked like the case might be reopened in a meaningful way.
A federal judge agreed to reopen Rubio’s habius corpus case in February 2022 and granted him further leave to appeal his conviction in federal court. A dispute even arose shortly afterward over which judge should actually hear the case with a state prison official seeking to have the original judge removed.
That motion was ultimately denied, though the original judge later recused himself voluntarily and a different federal judge took over the case in May 2022. But by April 2024, after two more years of proceedings, that federal challenge was denied as well. The fifth circuit court of appeals rejected his appeal in May 2025.
The US Supreme Court agreed to hear his final appeal, did so on December 11th, 2025, and ultimately rejected it on January 12th, 2026, closing off his last available avenue of legal review. The very next day, January 13th, 2026, Cameron County’s district attorney filed a motion to seek a formal execution date. On February 26th, 2026, that date was set, November 12th, 2026, at the Huntsville unit, more than 23 years after the crime that put him there.
The district attorney, who was not the prosecutor originally assigned to the case back in 2003, has said he intends to personally witness the execution when it takes place, describing the case as one of the most difficult to comprehend that his office has ever handled, even after two decades of familiarity with its details. In the months since that date was set, Rubio has spoken publicly about the case for the first time in a recorded interview, expressing remorse and saying he thinks about the three children every single day. In that interview, he described the
moments leading up to the killings from his own perspective, recalling Julysa’s behavior in the hours before her death and his own state of mind at the time without altering the fundamental facts already established by the courts. His legal team has also raised a separate and legally distinct question in these final months.
Not whether he was insane at the time of the killings back in 2003, which is a matter the courts have already settled, but whether he is currently competent to be executed. That is an entirely different legal standard focused narrowly on whether a condemned person at the time of execution understands the nature of the punishment about to be carried out and the reason for it.
That competency question remains an active unresolved part of his case. As this documentary is being made, Cameron County prosecutors have stated publicly that they intend to demonstrate Rubio understood exactly what he was doing on the night of the killings and that his execution should proceed as scheduled without further delay. The apartment where the killings took place no longer exists.
It was demolished in 2016, more than a decade after the crime, following approval from Brownsville’s Planning and Zoning Commission. In its place now stands Tress Angeles Park. Three trees planted for three children, a small green space built, where a family once lived under a single roof and where that family’s story came to its end.
Community members have gathered there for memorials repeatedly in the years since, including on the crime’s 10th anniversary in 2013, and again as recently as December 2025, on its 22nd anniversary, keeping the children’s memory present in a city that has clearly not forgotten them, even as the legal case dragged on for two more decades.
More than two decades ago, a young family in Brownsville, Texas, ran out of money, ran out of options, and ran out of time. All within the same handful of days in March 2003. What began as a story about poverty, eviction, and desperation became something far darker before it was finished. Something that no amount of financial hardship can fully explain or soften.
Angela Kamacho is serving a life sentence with a distant uncertain path to parole. John Alan Rubio is scheduled to die by execution in November 2026, more than 23 years after the crime that defined the rest of his life. And Julisa Casada, Johnny E. Rubio and Mary Jane Rubio, three children who should have grown up in that same South Texas city, gone to school there, and built their own lives there, never got the chance to become anything more than the reason this story had to be told at all.
Two juries, 23 years apart in their first and final verdicts, looked at the same set of facts, and reached the same conclusion each time. Two courts of appeal at the state and federal level reviewed that conclusion repeatedly across two decades and ultimately let it stand. Whatever was happening inside John Alan Rubio’s mind on the night of March 11th, 2003, whether it was a genuine severe break from reality or something the law was never going to accept as an excuse, the legal system built to answer that exact question has
now spoken as many times and as thoroughly as it is designed to.
