FBI special agent Christopher Combs said Ator called the agency’s tip line...making “rambling statements about some of the atrocities that he felt that he had gone through.” “He was on a long spiral of going down,” Combs said. “He didn’t wake up Saturday morning and walk into his company and then it happened. He went to that company in trouble.” ...Ator had previously failed a federal background check for a firearm, said John Wester, an agent with the federal Bureau of Alcohol, Tobacco and Firearms. Wester did not say when Ator failed the background check or why.
