A Life Cut Short: Examining the Execution of Moises Mendoza
The Brutal Crime that Sparked a Two-Decade Legal Battle
The disappearance of Rachelle O’Neil Tolleson in 2004 sent shockwaves through the small town of Farmersville, Texas. Her young daughter, Avery, was found alone in their home, surrounded by the chaos of what appeared to be a violent struggle.
Moises Mendoza, a young man who had a previous encounter with Tolleson, became a suspect. His confession to investigators, detailing the brutal kidnapping, strangulation, sexual assault, and ultimately the burning of Tolleson’s body, solidified his position as the prime suspect. Physical evidence, including Tolleson’s burned remains found in a nearby creek, further corroborated his admissions.
Twenty Years of Appeals and a Final Recourse
Moises Mendoza was on death row a few months shy of 20 years — as long as the woman he killed was alive. In Texas’ third execution of the year, the 41-year-old was put to death by lethal injection Wednesday evening in Huntsville.
Mendoza was condemned by a Collin County jury for kidnapping, strangling and sexually assaulting 20-year-old Rachelle O’Neil Tolleson — a new, devoted mother — in 2004 before setting her body on fire. He repeatedly confessed to the murder, and a series of appeals, largely alleging ineffective counsel at his 2005 trial, were rejected by the courts.

Mendoza, strapped to a gurney and covered in a white sheet, had a spiritual adviser, the Rev. Karsten Wedgewood from England, with him in the death chamber. Other witnesses listed for Mendoza were his wife, a sister and two friends. Witnesses for Tolleson included her parents, two brothers, a cousin and an uncle.
Mendoza used his final statement, which he delivered in both English and Spanish, to apologize to Tolleson’s family.
“I am sorry for having robbed you of Rachelle’s life,” he said. “I know nothing that I could ever say or do would ever make up for that.”
To his own loved ones, Mendoza said: “Don’t kill them with kindness — heal them with kindness and love. Always love. Love, love, love.”
The lethal solution began flowing into his arms at 6:07 p.m. As they watched from behind a panel of glass, Mendoza’s family blew kisses, prayed and wept.
And when his face began to gray, they started to sing, “All my life you have been faithful, and all my life you have been so, so good. With every breath that I am able, oh, I will sing of the goodness of God.”
A doctor entered the room about 15 minutes later, tilted Mendoza’s head and flashed a light in his eyes. He used a stethoscope to check for a heartbeat, and called his time of death at 6:40 p.m.
“He was put to sleep. He felt no pain,” Pam O’Neil, Tolleson’s mother, told reporters after the execution. “I wish I could say the same about my daughter’s death.”
She paused. “Justice delayed is not justice denied.”
The Crime, Confessions, and Investigation
The crime that led to Mendoza’s execution occurred on March 18, 2004, when Tolleson was reported missing after O’Neil found her 5-month-old daughter, Avery, alone in Tolleson’s Farmersville home.
The bedroom was in such disarray — broken furniture and clothes and papers strewn out of place — that court records state a responding police officer likened it to the aftermath of a tornado.
Mendoza, then 20, was brought in for questioning when it was revealed that days before Tolleson’s disappearance, the two were seen talking at a house party.
Tolleson, who was in the midst of a divorce, later told a friend she had no interest in Mendoza. Although Tolleson and her husband attended Farmersville High School with Mendoza, Tolleson’s family has said the three were never friends.
After days of searching, a man combing the bed of a Collin County creek for arrowheads on March 23 discovered Tolleson’s burned body, according to previous reporting by Unionjournalism.
She was identified by her dental records. Mendoza was arrested the next day, after a friend told police he had confided in her about his role in the killing.
In a letter he wrote to his parents, Mendoza said he “turned into the devil” when he did it, according to court records.
Mendoza told investigators he did not kidnap Tolleson, but that she willingly left Avery to sit with him in his pickup, where he choked her “for no reason.” He said they then had sex before he choked her again and “poked her throat” with a knife to ensure she was dead.
The Appeal to the Supreme Court
A Last-Ditch Effort to Spare Mendoza’s Life
Mendoza’s attorneys asked the Supreme Court to review a Texas Criminal Court of Appeals decision to deny a request that claims Mendoza’s counsel was ineffective.
Specifically, court documents state that Mendoza’s former attorney did not investigate testimony during sentencing from a jailer who claimed Mendoza had started a fight with another inmate.
Prosecutors were using the story to assert their claims that Mendoza remained a danger despite being locked up and was deserving of the death penalty.
In 2016, the inmate the prosecution claimed was attacked by Mendoza, Melvin Johnson, said in an affidavit he was the aggressor.
Johnson reiterated those claims again in a March 2025 affidavit where he claims Mendoza was only allowed out of his cell for recreation alone and that he had been let out with Mendoza and “knew the guards wanted me to jump him.”
“When my door opened with Mendoza out, I knew the guards wanted me to jump him, and that’s what I did,” Johnson said in the affidavit.
- The Supreme Court denied Mendoza’s appeal for a stay of execution.
- Mendoza will be executed Wednesday night for the 2004 murder of Rachelle Tolleson.
- Mendoza was the third person executed in Texas this year.
The Reaction to the Execution
Justice Carried Out, but at What Cost?
Attorney General Paxton released a statement after the execution, saying: “Tonight, the State of Texas upheld its duty and obligation to enforce justice and ensure that criminals receive the appropriate punishment.”
Collin County District Attorney Greg Willis confirmed the execution and issued a press release, saying: “Moises Mendoza was executed tonight for the 2004 abduction and murder of 20-year-old Rachelle Tolleson—a brutal, unforgivable crime that devastated her family and shocked our community.”
Willis continued, “From the very beginning, there was no real doubt about his guilt. He confessed. He led investigators to where he dumped Rachelle’s body and directed them to other physical evidence linking him to the crime.”
Willis emphasized, “Over the past twenty years, his conviction and sentence have been thoroughly reviewed by multiple courts, at both the state and federal levels. Each one affirmed what the jury decided: that the evidence was overwhelming, and the sentence was just.”
Willis concluded, “Tonight, justice was finally carried out. Nothing can undo what Rachelle’s loved ones have endured. But justice is not about erasing the past—it’s about honoring the life that was taken.”
Pam O’Neil, Tolleson’s mother, also reacted to the execution, saying, “He was put to sleep. He felt no pain. I wish I could say the same about my daughter’s death.”
O’Neil paused, then said, “Justice delayed is not justice denied.”
A Long Road to Execution:
Mendoza’s legal team mounted numerous appeals over the next two decades, challenging his conviction and arguing for ineffective counsel during his 2005 trial. These appeals were repeatedly rejected by courts at both the state and federal levels.
The Supreme Court’s Decision:
Mendoza’s final hope rested with the U.S. Supreme Court. His attorneys presented arguments about a potential miscarriage of justice, citing inconsistencies regarding testimony from a jailer who claimed Mendoza had been involved in a fight with another inmate. However, the Supreme Court declined to hear the case, paving the way for his execution.
