Texas Father Who Beheaded His Three Young Children Faces Execution After Final Appeal Is Rejected

A Texas death row inmate convicted of killing and decapitating his three young children is scheduled to receive a lethal injection on Thursday, November 12, more than 23 years after the horrifying murders shocked the community of Brownsville.

John Allen Rubio, now 46, was sentenced to death for the March 2003 killings of three children: Julissa Quesada, 3, John Esteban Rubio, 14 months, and Mary Jane Rubio, just two months old.

His execution date remains in place after the Texas Court of Criminal Appeals rejected his latest attempt to delay the punishment. The decision leaves Rubio facing execution at the Huntsville Unit unless another legal or clemency intervention changes the schedule.

The disturbing events behind the case

The murders took place on March 11, 2003, at the family’s home in Brownsville, South Texas.

Rubio and his common-law wife, Angela Camacho, were both convicted in connection with the killings. Prosecutors said the couple stabbed and decapitated the three children.

According to court records, Rubio told investigators that he believed the children were possessed by evil spirits. His defense team later argued that he suffered from paranoid schizophrenia and experienced delusions that influenced his actions.

Prosecutors, however, presented evidence that he understood the consequences of what he had done. Testimony during the trial included accounts suggesting that he had discussed the possibility of going to prison after the killings.

Camacho, the children’s mother, was also convicted and received three consecutive life sentences. She remains incarcerated.

Death sentence overturned before being reinstated

Rubio was initially convicted of capital murder and sentenced to death in 2003.

Four years later, the Texas Court of Criminal Appeals overturned the conviction and death sentence, ruling that statements made by Camacho had been improperly introduced as evidence against him.

The case went back to trial in 2010. A second jury again found Rubio guilty and sentenced him to death.

Since then, his legal team has continued challenging the conviction and sentence, including arguments involving his mental health and the fairness of the trial.

Lawyers make one more attempt to stop execution

In October 2026, Rubio’s attorneys filed another request seeking to halt the scheduled execution. They argued that prosecutors had failed to correct allegedly false testimony from a key witness during the 2010 trial.

The Cameron County District Attorney’s Office opposed the request, arguing that the defense had raised a similar issue in 2022 and that the appeals court had already rejected it.

The Texas Court of Criminal Appeals ultimately denied the latest request, leaving the execution date unchanged.

There was also a separate legal question over whether Rubio understood why he was being executed. In October, a judge reviewed expert evaluations and ruled that he was competent to face execution, finding that he understood his actions and the reason for his sentence.

Three children’s deaths remain at the center of the case

The case has remained deeply disturbing for the families and investigators involved for more than two decades.

At a court hearing in October, a relative of the children shouted at Rubio, expressing anger over the deaths and saying the family intended to witness his execution.

The Texas Department of Criminal Justice lists Rubio’s execution for November 12, 2026, at the Huntsville prison.

If carried out, the lethal injection will bring an end to a case that has passed through multiple trials and appeals since the three children were killed in 2003.

For now, Rubio’s execution remains scheduled, although the possibility of any last-minute legal or clemency action cannot be entirely ruled out.
