Chilling Videos, Journal Found as Parents Face Scrutiny in Michigan School Shooting [View all]
      
      Authorities on Wednesday identified the teenage suspect in the mass shooting a day earlier at Michigans Oxford High School as 15-year-old Ethan Crumbley, painting a picture of a clear-eyed teen who planned and executed a rampage that left at least four students dead and seven others, a teacher among them, injured.
Crumbley, a sophomore, was previously flagged by administrators for behavior in the classroom that they felt was concerning, Oakland County Sheriff Mike Bouchard said Wednesday. His parents had even been brought into the school the morning of the shooting for a face-to-face meeting about their sons behavior, according to Bouchard. He wouldnt say what the behavior was, and police werent informed about any potential issues prior to the tragic event.
Nathan Swanson, a 10th grader who was in some middle-school classes with Crumbley, told The Daily Beast that he was really quiet, he would never talk to people.
