HERKIMER, N.Y. (AP) – A man killed by police after a shooting rampage that left four people dead was a mystery in a small town, a stranger to his neighbors and a man of few words, even at a bar where he regularly drank Coors Light and listened to, but never sang, karaoke.

A former boss who worked with gunman Kurt Myers for 20 years described him as a quiet and nervous but intelligent and congenial man who was a fan of World War II trivia – though a recent encounter with his old employee left him unsettled.

Steve Copperwheat, who hired Myers as a machine operator in the early 1980s at Waterbury Felt, a manufacturer of industrial textiles, said he encountered him in a Walmart parking lot 3 months ago after not seeing him in about 10 years.
