Michigan prosecutors have filed charges against a Detroit-area homeowner for the fatal shooting of an unarmed African-American woman on his porch. Nineteen-year-old Renisha McBride was apparently seeking help after a car crash when she came to the door of the suspect, Ted Wafer. McBride was killed by a shotgun blast to the face. After a more than week-long investigation that saw the case attract national controversy, prosecutor Kym Worthy unveiled charges on Friday.

Kym Worthy: “She was found with a very large gunshot wound to her face. It’s alleged that she was shot to death by the homeowner after she knocked on his locked front screen door. By all reports, she was unarmed, and there were no signs of forced entry to the home. We obviously do not feel that the evidence in this case feels that the defendant acted in lawful self-defense.”

Wafer faces up to life in prison on charges of second-degree murder, manslaughter and possession of a firearm in a felony. He has claimed the gun fired by accident and that he thought McBride was an intruder. At a news conference, McBride’s mother, Monica McBride, addressed Wafer publicly.

Monica McBride: “I’m not going to call you a monster. You said it was an accident. When you accidentally do something to someone, you say you’re sorry or you apologize. You did no accident. You took a life, and you took a beautiful life that was starting to blossom into a beautiful woman.”
