Expert: Mich. porch shooter's gun did not go off accidentally

DETROIT - An expert says the shotgun used to kill a young woman on a porch in suburban Detroit porch wasn't accidentally fired by the homeowner.

Detective Sgt. Shawn Kolonich of the Michigan State Police testified Tuesday at the fourth day of trial for Theodore Wafer. The 55-year-old Dearborn Heights man is charged with second-degree murder in the death of 19-year-old Renisha McBride last fall.

Wafer says he shot McBride in self-defense after she repeatedly pounded on his doors before dawn last Nov. 2. An autopsy revealed the victim had a .218 blood-alcohol content at the time of the incident. But a recording played for the jury last week quotes Wafer as saying he didn't know the shotgun was loaded and that it went off accidentally.

Kolonich says his tests on the weapon show it couldn't have been fired without Wafer pulling the trigger.
