DETROIT (AP) — A defense lawyer for a Detroit-area man who killed an unarmed woman on his porch says he repeatedly heard poundings — "boom, boom, boom" — outside his home before he opened the door and shot her in the face.

Jurors heard opening statements Wednesday in the trial of Theodore Wafer, who is charged with second-degree murder in the death of 19-year-old Renisha McBride last November in Dearborn Heights.

The 55-year-old Wafer claims he acted in self-defense, but prosecutors say his actions were unreasonable. The shooting occurred around 4:30 a.m., 3 ½ hours after McBride crashed her car about a half-mile away. An autopsy found she was drunk.

Prosecutor Danielle Hagaman-Clark says Wafer could have called police instead of shooting McBride.

Defense attorney Cheryl Carpenter says Wafer feared for his life.
