|The Winehouse family awaits the outcome of an inquest into Amy’s death, due to begin October 26.|
Amy Winehouse didn’t have any illegal substances in her system when she died, and it is still unclear what killed her, her family said on Tuesday.
Toxicology tests showed that “alcohol was present” in the singer’s body but it hasn’t yet been shown whether or not that contributed to her death, the family said in a statement, reports Jill Lawless of The Associated Press.
Winehouse, 27, had exhibited erratic behavior for years, as rumors swirled about her drug and alcohol use. She was found dead in her London home on July 23, and an initial post-mortem failed to determine the cause of her death.
“Toxicology results returned to the Winehouse family by authorities have confirmed that there were no illegal substances in Amy’s system at the time of her death,” read a statement released by family spokesman Chris Goodman.
The family awaits the outcome of an inquest due to begin October 26, according to the statement.
Winehouse had “beaten” her drug addiction three years before her death, claimed her father, Mitch, but he admitted she was still “struggling to control” her drinking after several weeks of abstinence.
The Winehouse family has announced plans for a charitable foundation for people dealing with addiction, but the plans are on hold as someone else has registered the name Amy Winehouse Foundation.
Winehouse’s final recording, a duet with Tony Bennett on “Body and Soul,” is scheduled for release next month as a charity single.
