When British singer Amy Winehouse was found dead in her London home on July 23, many assumed she had OD-ed on heavy drugs, and only few believed her father Mitch when he said she’d been clean for the past 3 years. Those few were right, the toxicology report reveals.

The results of toxicology tests have been made public and they confirm what Amy’s father had been saying all along: the singer had been clean of drugs.

There was no trace of illegal substances in her body at the time of death, the Daily Mail reports, citing the official report – just like there was no trace of drugs in the apartment when police arrived.

However, tests revealed that Amy had been drinking when she went to bed and never woke up again, though whether that played any part in her death is yet to be determined.

“Results indicate that alcohol was present but it cannot be determined as yet if it played a role in her death,” a representative of the Winehouse family says.

“The family would like to thank the police and coroner for their continuing thorough investigations and for keeping them informed throughout the process,” adds the rep.

The exact cause of death will be announced later this year, when the police inquest concludes.

“They await the outcome of the inquest in October,” says the same family representative.

Nevertheless, the presence of alcohol in Amy’s blood at the time of her death contradicts what Mitch Winehouse said at the funeral about how she’d also kicked her alcohol addiction and had been about 3 weeks completely sober.

As we also noted at the time, Mitch and the family believed that Amy had been killed by abstinence, in the sense that she’d quit drinking cold turkey, sent her body in shock, went into seizure and slipped into a coma.
