Police say Clark does not have a history of mental illness. And, the only criminal mark against him was a DWI offense about 15 years ago. Police have searched Clark's home, computer and car and did not find anything that would give clues about why he went crazy.
Joe Zikuski says, "It's still puzzling. There's no indication of anything that we have found to this point that would make an individual, it's totally out of his character to do anything like this."
Clark lived in Greene. He was married and had a child.
