Sources tell us the deputy was in uniform and pumping gas when someone walked up and shot him repeatedly.

"We were driving on West Road and we heard the shots, and when I turned and looked, the lady was screaming over top of him. So we busted a U-turn into the parking lot and that's when we saw what had happened," witness Mckenzie Stalter said.

Stalter says she saw a woman sobbing over the officer's body.

"She was laying on top him. She was saying that was her best friend and that he had two kids," she said.

LifeFlight initially was dispatched to the scene, but it was later called off.

Stalter says the suspect was gone by the time she had pulled into the parking lot and called 911. A manhunt for that suspect is still underway. We're told officers searching for a red Ford Ranger tracked down the vehicle, but there were no suspects in sight.

Tonight's shooting marks the first time a Texas law enforcement officer was fatally shot this year. This is the first officer slaying in the Houston-area since 2012.
