John Allen Rubio was executed by lethal injection Thursday evening at a state prison in Huntsville, Texas, bringing to a close a case that has haunted South Texas for nearly 23 years. The 46-year-old Brownsville man was convicted of murdering three young children he had helped raise, in a crime that shocked the conscience of the community and the nation.
Rubio was pronounced dead at 6:47 p.m., 21 minutes after the lethal injection began. The execution, scheduled for 6 p.m., proceeded without incident. In his final statement, Rubio thanked friends and family for their support and acknowledged that he had changed since the crimes. He expressed love for his wife and apologized to her family, though he acknowledged that his death would not bring them happiness. He concluded by saying he was ready to join his children in heaven.
The crimes took place on March 11, 2003, inside a windowless apartment in Brownsville. Rubio and his common-law wife, Angela Camacho, killed three children: Julissa Quezada, age 3, John Esteban Rubio, age 1, and Mary Jane Rubio, just 2 months old. The children were stabbed and beheaded. While Rubio was not the biological father of the two older children, he had assumed a parental role in their lives.
Court records indicate that in the days leading up to the murders, Rubio claimed the children were possessed by demons. He cast himself as a chosen figure destined to save the world. Defense attorneys later argued that Rubio suffered from paranoid schizophrenia and entered a plea of not guilty by reason of insanity. Expert witnesses for the defense testified to his mental illness, but prosecution experts disputed these findings, and the jury ultimately found him guilty and sentenced him to death.
The defense also presented evidence of Rubio’s troubled upbringing, marked by violence, neglect, drug use, and exposure to prostitution. These factors, his attorneys argued, had severely impaired his development and contributed to his mental instability. The jury, however, determined that these circumstances did not absolve him of responsibility for his actions.
Angela Camacho pleaded guilty to her role in the murders and is currently serving a life sentence in prison. She avoided the death penalty through her guilty plea and cooperation with authorities.
The apartment building where these tragic events occurred has since been demolished. The property now serves as a community park and garden, a transformation that stands as a testament to a community’s effort to heal and move forward from an unspeakable tragedy.
Earlier the same day, Oklahoma executed James Pavatt, 73, for his role in plotting and carrying out the 2001 murder of his romantic partner’s estranged husband. Pavatt’s execution by lethal injection took place just hours before Rubio’s.
