'I turned into the devil': Moises Mendoza, a 'sadistic' killer, set for Texas execution
Five years ago this April, a rapist and killer described by one prosecutor as one of the most "violent, sadistic men" he'd ever encountered, was sentenced to Texas' death row.
Now Moises Sandoval Mendoza, 40, is set to die by lethal injection on Wednesday for the murder of 20-year-old Rachelle O'Neil Tolleson on March 18, 2004, in Farmersville, Texas. If the execution moves forward, Mendoza will be the third inmate executed in Texas this year and the 13th in the nation.
At the time of her death, Tolleson was a new mother to her 6-month-old daughter Avery. Tolleson enjoyed activities like scrapbooking and shopping, but her mother Pam O'Neil said it was Avery who was "her oxygen."
"Avery was her life and I was so proud of her when she became a mommy. Everything just came so naturally to her,' O'Neil told The Courier-Gazette about a year after Tolleson's death. "I hate that Avery won't have memories of her."
Over the years, Mendoza's case has gained a sort of notoriety. In 2006, his case was featured in the 10th season of "Forensic Files" and in 2008, the Investigation Discovery series "Solved" highlighted Tolleson's murder.
On April 2, Mendoza's lawyers asked for the opportunity to challenge Mendoza's conviction in federal court.
As Mendoza's execution approaches, USA TODAY is looking back at the crime, who Mendoza and his victim were and what led him down a path that will end in his own execution.
In the early hours of March 18, 2004, Rachelle O'Neil Tolleson was at home with her 6-month-old daughter Avery in Farmersville, Texas, a small town about 40 miles northeast of Dallas. Tolleson and Avery lived there alone, as Tolleson was in the middle of a divorce.
Mendoza let himself inside Tolleson's house through a back door that night, he told police, per court documents. The two then left, leaving baby Avery at home, to get a pack of cigarettes, Mendoza told police.
Mendoza told police that he drove a little while before he began to choke Tolleson in his vehicle "for no reason," according to court documents. Mendoza then drove the two to a field near his house, where he raped her before choking her again, court documents say.
Mendoza told police that he then dragged Tolleson out of his truck and choked her again until he thought she was dead. To make sure, he "poked her throat" with a knife. Mendoza left her body in the field, where it remained for a few days before he was interviewed by police about Tolleson's disappearance, court records say.
Paranoid, Mendoza wrapped Tolleson's body in a tarp and moved it to his cousin's land in a more remote area, just a few miles east of Farmersville. He then dumped the body in a "dug-out pit" and set it on fire to "destroy the fingerprints," he told police, as reported by The Courier Gazette.
A few days later, a man searching for arrowheads found Tolleson's charred body, according to The Courier-Gazette reporting.
Mendoza was convicted of murder and sentenced to death.
Before his conviction and sentencing, Mendoza wrote to his parents, telling them he didn't have a reason for what he did. "I don't know what happened to me at that moment. I turned into the devil and after I did something that I thought was in a dream," Mendoza wrote, according to The Courier-Gazette.
Neighbors described Mendoza as "hard-working" but said he changed as he got older, recounting a "violent argument" when he pinned down his mother and sister in their front yard once, as previously reported by The Courier-Gazette.
Mendoza graduated high school, where he did "fairly well," court documents state. He received a few high school scholarships and completed about nine months of heating and air-conditioning training upon graduating.
In 2003, Mendoza was arrested for his involvement in two aggravated robberies on the Dallas College Richland Campus, according to The Courier-Gazette reporting. It was while he was out on bail for one of these robberies that Tolleson went missing, the 2006 "Forensic Files" episode explains.
For much of their upbringing in northern Texas, Mendoza and Tolleson were actually in the same grade school classes, Tolleson's mother, Pam O'Neil, explained in a 2006 "Forensic Files" episode that outlines Mendoza's case. And the Friday before Tolleson's murder, Mendoza had been at Tolleson's house for a party of about 15 people, court documents say.
Clinical psychologist Mark Vigen described Mendoza during his trial as "immature" and "psychologically under-developed," claiming that Mendoza enjoyed getting away with "being sneaky" and got angry when others criticized him, as stated in court documents.
During Mendoza's sentencing, former Collin County First Assistant District Attorney Greg Davis described Mendoza as "one of the most violent, sadistic men" he'd ever prosecuted.

Why wasn't an Amber Alert sent for the 3 sisters found dead in Washington?
The deaths of three girls in Washington state whose mother reported them missing after their father didn't return them from a custodial visit, has prompted cries for reform because an Amber Alert was never sent for the sisters. The bodies of Paityn Decker, 9; Evelyn Decker, 8; and Olivia Decker, 5, were discovered on June 2 – just days after they were reported missing by their mother, Whitney Decker. The three girls did not return home from a planned visitation with their father, Travis Decker, a former military member who is homeless and was living out of a pickup. Authorities found the girls' bodies about 75 to 100 yards away from their father's unoccupied vehicle near the Rock Island Campground in Chelan County, about 148 miles east of Seattle. The FBI, Homeland Security Investigations, U.S. Marshals, and U.S. Border Patrol have joined the search for Travis Decker, whose whereabouts remain unknown. Now, Whitney Decker is calling for changes to Washington state's Amber Alert system and improvements in mental health care for veterans as the search for the man stretched into its sixth day on June 6, according to reports. Washington State Patrol was originally contacted on May 30 to request an Amber Alert, but the situation "did not meet the required criteria" at the time, Wenatchee police said. The agency instead issued a statewide Endangered Missing Person Alert (EMPA) for the girls on May 31. As authorities intensify the search for Travis Decker, 32, a family attorney told local media outlets that Whitney Decker believes her daughters might still be alive had an Amber Alert been issued in the hours after they were reported missing. "She really feels that the system let her children down," Attorney Arianna Cozart said in an interview with KING 5. "It was the inadequacies in the services for our veterans that killed those children." Court filings revealed that Travis Decker had exhibited mental health issues prior to the girls' deaths. Cozart told The Seattle Times that Travis Decker had been diagnosed with borderline personality disorder and complex post-traumatic stress disorder after leaving active service. "They did not see him as an immediate physical danger to his children, despite the fact that he had a well established history of mental health issues," Cozart added. "And had they had seen it that way, those children might still be alive. And that's the thing that is so brutal, and the one thing she's really hoping can be changed in this tragedy." Cozart did not immediately respond to USA TODAY's request for comment on June 5. 'One too many': Death of 3 girls in Travis Decker's custody is a familiar tragedy Chris Loftis, spokesperson for the Washington State Patrol, reiterated to USA TODAY that the request for an Amber Alert did not meet the system's guidelines, which are set by the U.S. Department of Justice. He said that, similar to other states, Washington's system has "specific criteria" to ensure that features of the program are only used in instances where the standards have been met. According to Loftis, the criteria include: "The person(s) must be 17 or younger." "The incident must be investigated by a law enforcement agency, and the subject must be entered into the National Crime Information Center." "There must be enough descriptive information that activating the alert will assist in the recovery." "There must be reason to believe the person has been abducted." "The missing person(s) must be known to be in danger of imminent serious bodily injury or death." While the first three criteria were met, Loftis said Travis Decker had limited custodial rights, and there was not immediate legal presumption that the girls were abducted when the Amber Alert requests were submitted on May 30 and May 31. He added that law enforcement does not "automatically have clear indication that the children are in danger" in situations where a custodial parent is late returning children to another parent. Loftis noted that discussions with local law enforcement did not mention danger as a concern. Citing notes from the intake specialist for Washington State Patrol's Missing and Unidentified Persons Unit, Loftis said initial and follow-up reports from local police stated there was no threat of great bodily harm or death to the children at the time. The notes also showed that Travis Decker had previously "never diverted from the parenting plan in the past" and "no alarming mental health status" had been mentioned in the reports, other than "he may be 'going through a lot' after leaving the military and weathering housing and employment issues." Though the case did not meet the Amber Alert threshold, Loftis said there was "ample concern" and State Patrol had enough information to issue the EMPA. Unlike an Amber Alert, the EMPA does not send a push notification or text message to all cell phones in the targeted area about missing children. According to Loftis, issuing an EMPA allows law enforcement to post electronic fliers, send text messages and emails to listservs of people who have requested notification on all alerts, post vehicle information on highway reader boards, and promote coverage by state broadcasters. "The State of Washington handled this incident no differently than any other state with the information they had available. But all of that said, nothing, no process, and no set of standards can protect us from all evils and horrors," Loftis said in a statement to USA TODAY. "We learn from every tragedy, and I'm sure we will review and learn from this set of tragedies, but the depth of this sorrow is beyond a learning opportunity right now, it is a tragedy first and forever." Community mourns amid manhunt: Who were Olivia, Evelyn and Paityn Decker? The three girls were found dead by apparent suffocation in a remote campground, according to the Wenatchee Police Department. Whitney Decker had reported the children missing on May 30 after they left their central Washington home to visit their father. On June 2, a Chelan County deputy found an unoccupied truck at about 3:45 p.m. local time near the Rock Island Campground. Officers found the bodies of the missing girls soon after, down a small embankment, according to a probable cause affidavit obtained by USA TODAY. While Travis Decker was nowhere to be found, investigators traced his cell phone, which revealed that he visited the same campground the day before the kidnapping, the court documents show. Travis Decker is wanted on charges of kidnapping, first-degree murder, and custodial interference in connection with the deaths, according to the Wenatchee Police Department. In an update on June 4, Chelan County Sheriff Mike Morrison said Travis Decker may have scoped out a hiding location before going off the grid using his extensive military and outdoor survival training.

Utah can execute convicted murderer who has dementia, judge rules
Utah can execute convicted murderer who has dementia, judge rules Show Caption Hide Caption Death penalty: Which states still use capital punishment The death penalty has been used in the U.S. since 1608. But various Supreme Court rulings have limited its use. Here's why it's controversial. Just the FAQs, USA TODAY A Utah judge on June 6 ruled a 67-year-old convicted murderer diagnosed with dementia on death row is competent enough to be executed. A trial court sentenced Ralph Leroy Menzies to death in 1988 for kidnapping, robbing and murdering 26-year-old Maurine Hunsaker, a married mother with three children. Since then, Menzies has been on death row. Menzies had chosen firing squad as his method of execution, according a ruling published by KUTV. While awaiting execution, he developed vascular dementia, and his lawyers had argued he was too incompetent to be executed. In a 22-page ruling, State Judge Matthew Bates said Menzies exhibited cognitive decline. But Bates said Menzies hasn't shown that his 'understanding of his specific crime and punishment fluctuated or declined in a way to offend the Eighth Amendment' of the Constitution, which protects against cruel and unusual punishment. Discover WITNESS: Access our exclusive collection of true crime stories, podcasts, videos and more Instead, Bates said in his ruling, 'Menzies consistently and rationally understands the reasons for his death sentence.' His lawyers tried to appeal his death sentence several times. Bates said Menzies' right to appeal the ruling was exhausted in late 2023, but news outlets report Menzies' legal team plans to appeal to the state Supreme Court. 'Ralph Menzies is a severely brain-damaged, wheelchair-bound, 67-year-old man with dementia and significant memory problems,' Lindsey Layer, a lawyer for Menzies, said in a statement published by multiple news outlets. 'It is deeply troubling that Utah plans to remove Mr. Menzies from his wheelchair and oxygen tank to strap him into an execution chair and shoot him to death.' USA TODAY has contacted Layer for comment. In an emailed statement, Madison McMicken, a spokesperson for the Utah Attorney General's office, said prosecutors were committed to seeking justice for Hunsaker. On Feb. 23, 1986, Menzies murdered Hunsaker while she was working as a cashier at a gas station in Salt Lake County, according to court records. He abducted her and stabbed her to death, leaving her body in the woods outside of Salt Lake City. Menzies had several past convictions for aggravated robberies before killing Hunsaker, who left behind three children, including a 6-month-old baby. Capital punishment: Supreme Court to consider use of multiple IQ tests in determining death penalty One of her children, Matt Hunsaker, was 10 when his mother was killed. He told KSLTV, a Salt Lake City TV station, that their family was one step closer to justice with the June 6 ruling. Menzies would be the sixth person executed by firing squad in the United States since 1976, according to the nonprofit Death Penalty Information Center. In 2019, the United States Supreme Court stopped the execution of an Alabama man convicted of fatally shooting a police officer because he had vascular dementia. Vernon Madison couldn't remember his crime or his punishment, justices ruled. In 2025, South Carolina executed two people by firing squad, the first such executions since 2010, when Utah last executed a person. The same day as Menzies' June 6 ruling, the Supreme Court said it would review using multiple intelligence tests to determine the death penalty against a person.

2 in custody after loaded, high-capacity weapons found outside graduation, sheriff says
2 in custody after loaded, high-capacity weapons found outside graduation, sheriff says The weapons found include what Oakland County Sheriff Michael Bouchard described as an AR-style pistol and a Glock semi-automatic handgun. Show Caption Hide Caption Are mass shootings accelerating in the US? Here's what we know. Can mass shootings cause more mass shootings? This is what the research says. Just the FAQs, USA TODAY Two people are in custody after sheriff's deputies in Michigan found loaded, high-capacity weapons in the parking lot of a high school graduation as a brawl unfolded on June 3. The weapons found include what Oakland County Sheriff Michael Bouchard described as an AR-style pistol and a Glock semi-automatic handgun. Both were loaded with 40-round magazines, including a drum and an extended stick, Bouchard said. The guns were not registered. Officials "probably prevented a mass shooting" in Pontiac, Bouchard said in a June 6 news conference. Sheriff's deputies were originally called out after reports of a brawl breaking out, but were told by an individual at the event that rumors of threats about a possible shooting were circulating on social media, according to Bouchard. Two people, ages 19 and 20, have been taken into custody, officials said. Neither was a graduating student but had disputes with others at the Arts and Technology Academy of Pontiac, which had its graduation on June 3, at the United Wholesale Mortgage sports complex. The motive behind the incident wasn't clear, Bouchard said. In a Facebook post, the Arts and Technology Academy said a "brief physical altercation" took place inside the venue that was handled by staff and security. The people were removed from the event and the commencement continued without disruption. Afterward, the altercation continued away from the venue, the school said. As deputies investigated, they learned those in the fight had been seen placing a packages under cars at the sports complex's parking lot, Bouchard said. The package, a backpack, turned out to have a weapon, Bouchard said. Another weapon was also recovered. A yet-to-be named 19-year-old suspect was in custody and is expected to face charges. A second suspect, Jamarion Hardiman, 20, was also taken into custody. Hardiman was on probation for a weapons offense, Bouchard said. Oakland County experienced a mass shooting in 2021. Then, a 15-year-old student murdered four classmates and injured seven others at Oxford High School, about 20 miles away from Pontiac. Eduardo Cuevas of USA TODAY contributed to this report.
