(LONDON) -- An inquest into the death of Amy Winehouse resulted in a verdict of "misadventure," reports the BBC.
The coroner determined that Winehouse was five times over the British legal limit for drunk driving, having had 416 mg of alcohol in her blood at the time of her death. The legal limit is 80 mg, or .08 percent. That makes Winehouse's blood alcohol level when she died .416 percent. In addition, three empty vodka bottles were found in her London apartment.
The BBC reports that the coroner, Suzanne Greenway, said, "The unintended consequence of such potentially fatal levels [of alcohol] was [Winehouse's] sudden and unexpected death."
The inquest also found that Winehouse had not had a drink three weeks prior to her death on July 23, which may have exacerbated the effect of alcohol on her body.
Prior toxicology reports determined that Winehouse had "no illegal substances" in her body at the time of her death.
