FORT WORTH, Texas (KWTX) A Texas sheriff's sergeant who died shortly after being found in his wounded head vehicle reportedly suffered a medical emergency and was not shot, as initially suspected by MPs, said Saturday. authorities.
The Tarrant County Medical Examiner's office determined that Sgt. Keith Shepherd had a pulmonary embolism.
After falling, he was able to get back to his car and was found Friday night by colleagues who had been looking for him while he was not returning from his break during his shift at the county jail.
The deputies first thought that he had been shot down, which prompted law enforcement to invade the area surrounding the county jail in Fort Worth.
But Fort Worth police, who is leading the investigation, said Saturday earlier that there was no evidence of a shootout.
"We just have to follow the facts until we understand what happened," said Tarrant County Sheriff Bill Waybourn, hours after Shepherd's discovery.
It was originally thought that a suspect might be on the run, but Waybourn warned that there was apparently no permanent threat to the public.
"We will take it piece by piece and see if we can find the answers," he said.
The investigators found blood inside and outside the car and they planned to watch the surveillance video of the area to better understand what happened.
Shepherd had been working for the sheriff's department for 19 years and had been assigned to prison.
