Fort Bend County Precinct 4 Deputy Constable Caleb Rule died last Friday when he was mistakenly shot by a Fort Bend County Sheriffs Deputy. Deputy Constable Rule touched the hearts of so many. Deputy Rule, theres just no easy way to describe him. He was a great officer, a great family man, said Chief Deputy John Hermann with Fort Bend County Precinct 4. There was a 21 gun salute, the playing of taps with a flyover from a Fort Bend County helicopter.
