The 19-year-old Detroit woman was shot and killed on the front porch of a Dearborn Heights home on Nov. 2.

On Thursday a toxicology report was released which showed McBride had a blood alcohol level nearly three times the legal limit for drivers.

The report from the Wayne County Medical Examiner's Office said Renisha McBride's alcohol level was 0.218 percent. The legal limit for drivers in Michigan is 0.08 percent.

The report said McBride also had marijuana in her system when she was shot in the face by a homeowner after approaching his house after a car accident.

Police have said that the unidentified homeowner's shotgun accidentally discharged. Lawyers for McBride's family claim she was simply looking for help after the accident, while those representing the homeowner said the 54-year-old man's actions were justified.

Gerald Thurswell, an attorney representing McBride's family, said the autopsy findings were irrelevant.

"I don't think the fact that she was intoxicated changes anything," he said. "Her being intoxicated on the toxicology report would make her less of a threat than more of a threat. The bottom line is, he should've called 911 when he heard a disturbance, and we know for a fact that the police would've been there in two minutes. Instead, he did the reverse. He took his shotgun, went on the porch, and blew her head off and then called 911."

Mark Carpenter, a lawyer for the homeowner, said he would not comment on the toxicology report until after the prosecutor's announcement Friday.
