Man shoots self in the head while handcuffed inside cop car after Austin police arrest him for shoplifting

A man arrested for allegedly shoplifting at a Texas mall shot himself in the head while handcuffed inside a cop car, police said.

Austin police responded to an incident around noon Sunday at Barton Creek Mall where they arrested a man for shoplifting and possession of a controlled substance, Interim Chief Brian Manley said.

The suspect, who was not carrying identification, might be in his late teens or early 20s, he said.

While in custody, officers found that the suspect had possible outstanding felony warrants. Officers then cuffed him and placed him inside a patrol car and were headed to police headquarters to identify him through fingerprinting, Manley said.

During the 6-minute ride, the suspect expressed suicidal thoughts. When the arresting officer asked him if he was armed, the man replied, yes.

The suspect then managed to pull out a pistol from his waistband while still handcuffed to shoot himself in the head, Manley said.

Emergency responders brought the suspect to University Medical Center Brackenridge with life-threatening injuries.

The incident, which was captured on video, will be investigated by the police departments internal affairs division to determine if the arresting officer an 11-year veteran followed protocols, Manley said.
