MINNEAPOLIS (AP) — An Israeli immigrant who started a signage company in his basement and spent decades building it into a successful business was among five people slain by a fired employee at a Minneapolis workplace, authorities said.

Also killed were an avid sculptor and painter with a day job there and a UPS driver who made pickups and deliveries to the company for years. Police said he was simply in the wrong place at the wrong time.

Six people — including the suspected gunman — were shot to death Thursday afternoon at Accent Signage Systems, located in a quiet residential corner of northwest Minneapolis. Police say Andrew Engeldinger, 36, was fired from the company that afternoon and responded by fatally shooting others there before he turned the gun on himself in the building's basement.
