Robert Cyprian, 49, died early Thursday at Lyndon B. Johnson General Hospital, according to the Harris County Sheriff's Office. He had been taken to the hospital the day before for a medical emergency. He was pronounced dead at 1:07 a.m. on Oct. 29.
Cyprian was sentenced on Oct. 20 to three years in the Texas Department of Criminal Justice for two counts of retaliation. He was awaiting transfer to state prison when the emergency happened.
Houston police are investigating the death, as state law requires for deaths in jail custody. The Sheriff's Office Internal Affairs Division is conducting a separate review to determine whether policies and procedures were followed. The death was reported to the Texas Commission on Jail Standards. The Harris County Institute of Forensic Sciences will perform an autopsy to determine the cause of death.
