One Harris County, Texas, deputy was killed and two others were wounded while working security at a Houston bar—a shooting that authorities called an “ambush.” Investigators believe the officers were looking into a possible robbery at the site when the gunman “came out of nowhere” and opened fire. According to the Houston Police Department’s Executive Assistant Chief James Jones, police have detained a person of interest. Harris County Precinct 4 Constable Mark Herman called it one of the “toughest things [he’s] done in [his] career” and expressed his hope for “swift and quick justice.”
