AMyWinehouseAutopsy230.jpgAn autopsy conducted on Amy Winehouse's body in London Monday morning revealed that the singer may have "died a violent or unnatural death."

The coroner has labeled the case a Section 20 postmortem, which means "there is reasonable cause to suspect that a person has died a violent or unnatural death or in any other way which would require an inquest."

At the scene of Winehouse's death, police determined it "non-suspicious," but the coroner's findings indicate that a more lengthy investigation will now begin.

Toxicology was done but results are not yet available.

The singer's body was identified by her parents early Monday morning and will be released to her family soon so that they can prepare a memorial service. Winehouse's family released a statement saying they have "been left bereft" by her death (see video below).

A shrine from fans can be seen at her London home -- candles, photographs, flowers and more adorn the street.

Winehouse, who had a long history of drug and alcohol abuse, was found dead "alone in her bed" by one of her security staff, according to her rep, on Saturday morning. She was 27.

The entertainment industry has commented heavily on her death, especially via Twitter. Winehouse's friend Russell Brand, a former addict, wrote about the loss, demanding that addiction be taken more seriously.
