COLUMBUS, Ohio (AP) — An Ohio State University janitor who was about to lose his job walked into a maintenance building for his early morning shift Tuesday and shot two supervisors, killing one of them and fatally shooting himself. No students were hurt.



Nathaniel Brown, 51, arrived for work at the nation's largest university dressed in dark clothing, a hooded sweat shirt and a backpack. He then opened fire in an office suite using two handguns, campus Police Chief Paul Denton said.



Brown spent five years in prison in the 1970s and '80s for receiving stolen property but lied about it on his job application, records show. It wasn't immediately clear whether Ohio State had done a background check on him.



Ohio State released documents from Brown's personnel file showing that supervisors complained he was tardy, slept on the job and had problems following instructions.
