Red Flags Point to Heaping Trouble for Teen School Shooter

New details are coming out about the 17-year-old high school senior who shot his principal and vice-principal yesterday in Omaha. A number of red flags apparently point to trouble brewing in Robert Butler, Jr.'s life, beginning with his transfer to a large city high school.  He had recently moved in with his father, an Omaha police officer, after living for years with his mother, according to the Omaha World-Herald.  Butler was unhappy with the move and struggled to find a place in his new school. A sequence of events yesterday morning led to the shooting.
