PITTSBURGH (AP) — Authorities say a man fleeing Pittsburgh police seriously injured himself when he jumped from the roof of a two-story home. The officers spotted a man they knew was wanted on warrants. They chased after him on foot, but he ran into a home and hid. Officers eventually spotted him on the roof, lying on his stomach. After defying instructions to stay put, the man jumped onto one neighboring roof and then another before injuring himself when he jumped two stories to an alley below.
