The deputy was identified as Sgt. Keith Shepherd, a 19-year veteran with the Tarrant County Sheriff's Office. 

"I can tell you what I know about Keith is that he had a great reputation at the Tarrant County Sheriff's Office," said Sheriff Bill E. Waybourn said. "He was a strong leader. He was loved. He was a great husband and a good father."

The sheriff said Shepherd had gone to lunch Friday but never returned to the Tarrant County Sheriff's Office.

Shepherd was transported to Texas Health Harris Methodist Hospital, where he was later pronounced dead.

While police said there was no suspect information at this time, Waybourn said he believed there was no immediate threat to the public.
