A new investigation into the death of singer Amy Winehouse found that she died of accidental alcohol poisoning , authorities in London said Tuesday . The conclusion was the same as that of an earlier investigation , which had to be thrown out because the coroner did not have the right qualifications . The Grammy Award-winning artist , who had battled with alcohol and drug abuse for several years , was found dead at her north London home on July 23 , 2011 , at age 27 . The new inquest was ordered in December by the London borough of Camden . Dr Shirley Radcliffe , interim coroner for Inner North London , gave a verdict of `` death by misadventure '' Tuesday , meaning the death is judged to be accidental , with no law broken and no criminal negligence involved . Winehouse `` had a history of excessive alcohol ingestion for some years and was under the care of a number of physicians , '' Radcliffe told the court , according to a summary provided by Camden Council . `` She had had a period of abstinence from alcohol for 12-13 days in July but a few days before her death she began to drink alcohol again . `` Following her death the police attended and deemed the death to be non-suspicious . Toxicological analysis revealed a level of alcohol commonly associated with fatality .

The pathologist found no traces of tablets in Winehouse 's stomach and said her organs appeared to be normal . The singer 's soulful , throaty vocals brought her stardom in 2007 , but her troubled off-stage life -- chronicled in her top 10 hit `` Rehab '' -- won her notoriety . Her death came less than two months after her latest release from a rehabilitation program and weeks after she was booed offstage by disappointed fans in Serbia .
