As family and fans grieve for the death of Singer Amy Winehouse who was found dead last week in her apartment, questions arise as why the 27 year old star passed away too soon. So far, the cause of death is unknown, but sources reports there were no signs of drug abuse near her body.
People.com:

Amy Winehouse may have been dead for up to six hours before a security guard found her body in bed at around 4 p.m. London time on Saturday.

The five-time Grammy winner last spoke to her security team at 10 a.m. Saturday, telling them she was going to sleep. Rigor mortis had set in by the time she was found, suggesting she had been dead for several hours.

Sources tell Britain’s Sun newspaper that Winehouse, 27, had seen a doctor Friday night as part of a routine series of regular checkups, given her battle with addiction. The doctor saw nothing amiss.
Winehouse had been strong enough that same night to play a drum kit in her bedroom – so loud that neighbors complained.

Cause of death is not yet known; a toxicology report could take weeks to complete.

A police source tells PEOPLE there was no paraphernalia or sign of drugs in Winehouse’s Camden home, which became the scene of makeshift memorials following news of the troubled singer’s death.
