Tarrant County Deputies Used Brain-Dead Detainee's Thumbprint on Release Form; State Jail Regulator Ruled It Invalid

Bolts reports that Tarrant County sheriff's deputies pressed the thumb of a brain-dead detainee onto a bond release form, and the Texas Commission on Jail Standards later ruled he remained in custody when he died.

Bolts reports that in June 2026, Tarrant County jailers sent Mack Greer to a hospital, where doctors told his family he was brain dead from massive bleeding. Deputies then brought a personal bond form signed by a judge and, according to Greer's parents, pressed his thumb onto the signature line. The sheriff's office said no outside investigation was needed because Greer had received a "compassionate release." Bolts reports the Texas Commission on Jail Standards ruled days later that he had not signed and remained in custody, and appointed the Haltom City Police Department to investigate. Bolts says that report describes Greer banging his head in a cell and a later episode of slurred speech and facial drooping. Sheriff's office spokesperson Laurie Passman said the claim that such releases avoid accountability is "entirely inaccurate." The county medical examiner ruled natural causes.

Why it matters

Texas law requires outside investigations of deaths in jail custody, and Bolts reports the sheriff's office has repeatedly been accused of avoiding them. The state regulator's ruling that Greer was still in custody bears on whether such releases can be used to avoid that scrutiny.
