Murder Story

Joe Mario Trevino Jr. committed a murder on January 17, 1983, in Tarrant County, Texas, when he was 20 years old. On that day, Trevino broke into the home of 80-year-old Blanche Miller while she was outside drying clothes. He started taking her belongings and loading them into her car. When Miller saw him, she attempted to call the police. Trevino then took the phone from her and strangled her. After that, he drove away in her car, taking some of her jewelry and stereo equipment with him.

Later that day, Miller's granddaughter found her body between 3 and 3:30 p.m. Trevino was arrested later that same day at his home. Police discovered Miller’s car and some stolen items in his possession. Initially, Trevino agreed to sign a confession but claimed that it was not he who killed Miller but a companion who was present.

During his trial, Trevino maintained that he had only been there and did not commit the murder. His trial started on June 20, 1984, and concluded on July 3, 1984. He was convicted of capital murder and sentenced to death by lethal injection.

Trevino filed his first appeal in 1985, arguing that a lack of diversity in the jury violated his rights. After several years, the appeal was reviewed in 1991 and was ultimately denied in 1994. After multiple appeals were filed and denied, Joe Mario Trevino Jr. was executed by lethal injection on August 18, 1999, at the age of 37. He declined to make a final statement before his execution.
