RALEIGH, N.C. (AP) — An Army veteran who suffered from post-traumatic stress disorder was killed in an exchange of gunfire with law enforcement at a church in the North Carolina mountains, officials and a charity said Thursday. The shooting on Wednesday happened after officers from multiple agencies responded to an emergency call claiming four people were shot, according to a news release from the State Bureau of Investigation. When the operator calls back, the man becomes angry and responds with expletives when asked again about how many people are shot. The charity trains service dogs to help children with autism and veterans with PTSD, brain injuries and problems with mobility.
