Pottsboro Police have released additional details regarding their investigation of a man who shot himself during a traffic stop on Wednesday.

In an emailed statement released Friday, Pottsboro Police Department Chief Shone Nix said at approximately 1:30 p.m. on Wednesday, a Pottsboro Police officer initiated a traffic stop of Timothy Heller, 50, in the 100 block of Pat Lane. Nix said Heller was wanted in Fayette County, Tennessee, on a felony charge of vehicular homicide by intoxication and the officer who initiated the stop was assisting the Joint East Texas Fugitive Task Force in Heller’s arrest.

“As the Pottsboro officer attempted to make contact with Heller during the traffic stop, Heller produced a handgun and shot himself one time while seated in driver’s seat of the Ford pickup,” Nix said in the statement. “Officers provided immediate medical attention to Heller until paramedics arrived and transported Heller to a local hospital. Heller was subsequently pronounced dead at the hospital by medical personnel.”

The incident drew a large police presence to the scene, including deputies of the U.S. Marshals Service, Texas Department of Public Safety and Grayson County Sheriff’s Office.

Heller’s body has been sent to the Dallas County Medical Examiner’s Office for an autopsy. Heller’s death is considered to be a “custodial death” and is currently under investigation by the Texas Rangers.
