The BBC is reported that singer Amy Winehouse has died. The 27 year old Grammy winner was found dead in her apartment in London. The cause of death has not yet been determined. The official police statement is as follows:

“Police were called by London Ambulance Service to an address in Camden Square NW1 shortly before 16:05hrs today, Saturday 23, July, following reports of a woman found deceased. On arrival officers found the body of a 27-year-old female who pronounced dead at the scene. Enquiries continue into the circumstances of the death. At this early stage it is being treated as unexplained.”

The young singer has had a troubled past with drug and alcohol abuse, and has been in rehab several times, most recently in May of this year. She recently cancelled the remainder of her European tour after being boo’ed while performing onstage. The singer had appeared drunk, mumbling the words to the songs and leaving the stage several times during the show.

As readers of Celebrity Diagnosis know, an autopsy will be performed to determine the cause of death. Because toxicology testing will have to be done, the final autopsy results specifying the manner and cause of death will probably not be released for at least 6-8 weeks. We will report when those results are available.

It is always a tragedy when a young person’s life is ended early. Ms. Winehouse joins a tragic pantheon of rock stars all of whom died at age 27, including Kurt Cobain, Janis Joplin, Jimi Hendrix, Jim Morrison, Brian Jones, Mia Zapata, Pete Ham and others.

UPDATE: July 25, 2011

Preliminary results on Amy Winehouse’s autopsy has not established a cause of death. This means that there was nothing visually abnormal when her body and internal organs were examined. Pathologists must now look at thin slices of tissues under a microscope and also wait for the results of chemical tests that might show drugs or other poisons in her blood.
