premise: Friends have said Poplawski was concerned about his weapons being seized during Barack Obama's presidency, and friends said he owned several handguns and an AK-47 assault rifle. Three officers killed. Autopsies show Sciullo, 37, died of wounds to the head and torso. Mayhle, 29, was shot in the head. A witness awakened by two gunshots told investigators of seeing the gunman standing in the home's front doorway and firing two to three shots into one officer who was already down. Sciullo was later found dead in the home's living room, and Mayhle near the front stoop, police said. A third officer, Eric Kelly, 41, was killed as he arrived to assist the first two officers. Kelly was in uniform but on his way home when he responded and was gunned down in the street. Kelly's radio call for help summoned other officers, including a SWAT team.
hypothesis: Sciullo was killed by Poplawski.
