Amy Winehouse died from too much alcohol, coroner says

(CBS/AP) LONDON - A coroner says that Amy Winehouse died as the unintended consequence of drinking too much alcohol.

Coroner Suzanne Greenaway gave a verdict of "death by misadventure," saying the singer had voluntarily consumed alcohol and risked the consequences.

The singer, who had fought drug and alcohol problems for years, was found dead in bed at her London home on July 23 at age 27. An initial autopsy proved inconclusive, although it found no traces of illegal drugs in her system.

A pathologist told the singer's inquest Wednesday that Winehouse had consumed a "very large quantity of alcohol" and was more than five times over the legal drunk-driving limit when she died.

At her funeral, her father, Mitch Winehouse, told mourners that his daughter had "conquered" her drug addiction and was "trying hard to deal with her drinking," according to the Daily Mail. He also reportedly said that Winehouse was the happiest she had been in a long time in the weeks before her death.

On Tuesday, British police admitted material relating to the inquest was delivered to a wrong address. BBC News reports that the file, thought to outline the circumstances of how Winehouse died, was meant to be sent to her family and was handed in to a north London police station.
