The victim, Carlos Rodriguez of Dallas, was discovered in his cell with multiple stab wounds at the Texas Department of Criminal Justice maximum security unit.
TDCJ public affairs personnel said a correctional officer making his rounds discovered the victim at 2:50 p.m. Friday.
McConnell Unit medical staff members were called to the cell and they had EMS personnel from Angel Care Ambulance Service dispatched to the scene.
Rodriguez was rushed to Christus Spohn Hospital in Beeville where he was pronounced dead.
Investigators with the TDCJ’s Office of the Inspector General have been questioning Rodriguez’s cell mate.
The suspect’s name was not released because no charges have been filed as of Monday.
He was described as a 26-year-old Hispanic male from Dallas.
Rodriguez, also of Dallas, was serving a life sentence for manslaughter, and failure to stop and render aid.
He had been incarcerated by the state since Oct. 28, 2004.
The cell mate was admitted to the TDCJ on Nov. 1, 2006. He was serving a six-year sentence for two counts of burglary of a habitation, assault with bodily injury, theft and burglary of a building.
