 Butler County Sheriff Michael Sloop confirmed Monday that a local officer made contact with the gunman after being hoisted up to the roof by another officer, but fled when the sniper pointed his AR-style assault rifle at the officer. I would have done the same thing, absolutely, the sheriff said. All I know is the officer had both hands on the roof to get up on the roof, never made it because the shooter had turned towards the officer and rightfully and smartly the officer let go, Sloop told KDKA.
