Harris County Precinct 3 Asst. Chief Deputy Clint Greenwood, a veteran law enforcement officer and attorney, was shot in the neck and killed this morning by a killer who is still on the run.

A deputy constable has died after being shot at the courthouse in Baytown.

Baytown police identified Harris County Precinct 3 Asst. Chief Deputy Clint Greenwood, a 30-year law enforcement veteran, as the victim in this morning’s shooting.

There was no word on the suspect, who is presumed to still be on the run after the shooting at 7 a.m. There was no description given of the shooter.

Authorities tell reporter Jeff Ehling the shooting happened at the back of the courthouse. Investigators said Greenwood was shot in the neck and radioed for help, reportedly saying “I’m bleeding out.”

Another deputy nearby rushed to his aid, applying pressure to Greenwood’s neck. They were able to get him help, flying him via Life Flight to Memorial Hermann Hospital, but sadly, he has died of his injuries.

Baytown police said it was not clear if Greenwood was targeted or the circumstances behind the shooting. They did not release any further information about the shooter.

Greenwood was shot outside the courthouse without any apparent warning. Texas Governor Greg Abbott released a statement on the murder.

No information about the suspect, his vehicle, or other details of the shooting have been made publicly available at this time, but the circumstances of the shooting—someone lying in wait at Greenwood’s place of work at a time he was expected to arrive, and no reports of any warning—would suggest to me that this was either the work of someone targeting Greenwood specifically, or who was hoping to take out any law enforcement officer at that location who presented himself as a target of opportunity.
