Assistant Chief Deputy Constable Clint Greenwood, a 30-year veteran, was shot at least once at 7 a.m. local time, Baytown Police Lt. Steve Dorris said during a news conference.

Greenwood was shot in the neck, but was still able to radio for help, saying, "I'm bleeding out," KTRK reported. He was quickly administered aid at the scene and eventually lifeflighted to a Houston hospital, however, none of the measures prevailed.

“He succumbed to his injuries. He did not survive,” Dorris said.

Though no information on a possible suspect was given, Dorris said authorities “don’t have any indication that tells us he’s gonna go out and target anybody else.”

Baytown Police are working the investigation in conjunction with a host of other agencies.

The shooting was intentionally done, Dorris said, however, a motive remained unclear.

"Whether or not he was specifically targeted, or whether this was because of the uniform he was wearing or the place he pulled up to in the morning, we just don't know that right now," Dorris said.
