As friends and family mourn the victims of Thursday's theater shooting in Louisiana, investigators are gathering clues on the alleged gunman for Phenix City, Alabama. Police say John Houser booby-trapped his Alabama home to keep anyone from living there after his pending eviction. The new owners found the gas starter tube in the fireplace was twisted out and ignited, the logs removed. Houser had grown into someone better known by neighbors and colleagues as an angry provocateur. In April 2008, Houser's wife, daughter, and others filed court papers seeking a temporary protective order against Houser for acts of family violence, and a history of manic depression and bi-polar disorder. Police say his anger culminated Thursday night in a slaughter at a movie theater in Lafayette, Louisiana, leaving two women dead and nine other people hurt. Houser fatally shot himself inside the theater.
