Three Harris County Jail Inmates Die Within Eight Days, All After Medical Emergencies - Causes Await Autopsies
Robert Cyprian, Don Johnson and Nickie Costello died between October 29 and November 5. Outside agencies are investigating each death, and the sheriff's Internal Affairs is reviewing all three.
Three men held in the Harris County Jail died within an eight-day period following separate medical emergencies, according to Harris County Sheriff's Office reports carried by the Texas Herald News. The deaths occurred between October 29 and November 5, 2026, involving inmates aged 40 to 60; two were pronounced dead at Houston hospitals and the third died in the jail's medical clinic.
Robert Cyprian, 49, was pronounced dead at Lyndon B. Johnson General Hospital at 1:07 a.m. on October 29, after being transported the previous day following a medical emergency. He had been booked on October 18 and sentenced on October 20 to three years in state prison on two counts of retaliation, and was awaiting transfer. Don Johnson, 60, was pronounced dead at approximately 6 a.m. on November 1 in the jail's medical clinic, after being taken there for treatment that morning; he had been in custody since May 20, 2026, on two counts of aggravated assault of a family member and one count of injury to an elderly person. Nickie Costello, 40, was pronounced dead at St. Joseph Medical Center at 3:38 p.m. on November 5 after a medical emergency earlier that day; he had been in custody since October 16, 2021 - more than five years - awaiting a December court date on a capital murder charge.
Under Texas law, deaths in jail custody are investigated by an outside law enforcement agency: the Houston Police Department is investigating Cyprian's death, and the Texas Rangers are investigating the deaths of Johnson and Costello. All three deaths have been reported to the Texas Commission on Jail Standards, and the sheriff's Internal Affairs Division is conducting separate reviews of whether jail personnel followed applicable policies and procedures - reviews the sheriff's office described as standard practice after an in-custody death.
The official causes of death remain pending. The Harris County Institute of Forensic Sciences will conduct autopsies to determine them, and no cause has been announced for any of the three men.
