( CNN ) -- A 19-year-old Detroit woman who was shot and killed on the front porch of a Michigan home had a blood alcohol level nearly three times the legal limit for drivers in the state , according to a toxicology report released Thursday . Wayne County Prosecutor Kym Worthy , meanwhile , was scheduled to make an announcement Friday about a review of possible charges against the homeowner who fired the fatal shotgun blast . The report from the Wayne County Medical Examiner 's Office said Renisha McBride 's alcohol level was 0.218 % . The legal limit for drivers in Michigan is 0.08 % . 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 do n'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 . An autopsy report said McBride was not shot at close range . As reported in The Detroit News this week , McBride 's autopsy left many questions unanswered . The autopsy confirmed that McBride had been shot in the face but revealed little about how the early morning incident unfolded on November 2 . `` There was an entrance shotgun wound to the face , with no evidence of close range discharge of a firearm noted on the skin surrounding this wound , '' said the autopsy report , which ruled her death a homicide . Detroit woman 's autopsy leaves questions . McBride was in a car accident earlier that morning , but police said hours passed between the time of the wreck and her death . A woman told police that she helped McBride after the car crash , but that McBride said she wanted to go home and walked away from the scene , the Detroit News reported . The wreck happened about 1:30 a.m. ; the shooting at 3:40 a.m . The homeowner said that he was awakened before dawn and believed someone was trying to break into his home .
