The crazed mass shooter who shot dead three students and left five others in critical condition at Michigan State University was identified Tuesday as 43-year-old Anthony Dwayne McRae. The gunman was identified as police confirmed he was found dead of suspected self-inflicted gunshot wound at 11:35 p.m., just over three hours after he first opened fire. Cops earlier said the killer was not thought to be connected to the university, and police did not reveal a possible motive in Tuesday’s early morning update.
