A Texas constable and two others were shot dead Monday in about a half an hour of gunfire near Texas A&M University, police said. Scott McCollum, assistant chief with the College Station police department, told reporters Monday afternoon that the three people killed were a Brazos County constable, the man authorities say exchanged gunfire with law enforcement officers and a male civilian. The National Law Enforcement Officers Memorial Fund noted that the slain constable, Brian Bachmann, is the sixth law enforcement official killed so far this year in Texas, according to a report of CNN.
