The Texas Rangers and the Burnet County Sheriff’s Office are investigating the July 5 death of a 47-year-old county jail inmate.
The man, identified as Donald O’Neill, was arrested the same day on a charge of violation of an emergency protection order. According to a statement by the sheriff’s office, the man was arrested “without any use of force on the part of the arresting deputies or Mr. O’Neill.”
Deputies took the man to the Burnet County Jail. During a routine medical screening, officials determined O’Neill was “in the midst of a possible medical episode,” according to the statement.
As a precaution, the man was taken to the Ascension Seton Highland Lakes Medical Center emergency room for evaluation and treatment.
After several hours at the hospital, O’Neill was released and taken back to the jail. He was again medically screened, according to the BCSO statement, and processed into the facility.
Later, during routine cell checks, jail staff found O’Neill unresponsive.
“The jail staff attempted CPR and utilized an (automated external defibrillator) for over 10 minutes while EMS was en route,” according to the sheriff’s office statement.
Burnet Fire/EMS arrived and transported O’Neill back to Ascension Seton Highland Lakes, where he was pronounced dead at approximately 11:30 p.m. July 5.
