DETROIT [[AP) -- A former medical examiner sparred with a prosecutor Thursday over a wound on the hand of a woman who was fatally shot on a Detroit-area porch, telling jurors it seems to fit the defense's claim that Renisha McBride was pounding on the homeowner's doors before she was killed.

Dr. Werner Spitz, a forensic pathologist, said photos of McBride's body show a "small superficial laceration" on her left hand. It "could have come from pounding on something," Spitz said.

The testimony was intended to reinforce Theodore Wafer's explanation that McBride, 19, was pounding furiously on his doors before he shot her last Nov. 2. Wafer insists he acted in self-defense, but prosecutors say he could have kept the front door closed and called police.
