Winehouse autopsy did not establish cause of death

LONDON — Police say the autopsy performed on Amy Winehouse did not establish her cause of death. The Metropolitan Police said Monday that further toxicology tests are needed and the results are expected in two to four weeks.

However, a coroner's official in London says there are no suspicious circumstances in the death of the 27-year-old singer, who was found dead in her bed on July 23.

Coroner's officer Sharon Duff told reporters Monday that "the scene was investigated by police and determined non-suspicious."

A family spokesman says a funeral will be held Tuesday for family and close friends. The spokesman says the time and place of the private funeral will not be made public.

An inquest into Winehouse's death was opened and adjourned at London's St. Pancras Coroner's Court. During the two-minute hearing, an official read out the name, birth date and address of Winehouse, described as "a divorced lady living at Camden Square NW1."

"She was a singer songwriter at the time of her death and was identified by her family here at St. Pancras this morning," said coroner's officer Sharon Duff.

In Britain, inquests are held to establish the facts whenever someone dies violently or in unexplained circumstances. Assistant Deputy Coroner Suzanne Greenaway said Winehouse's inquest would not resume until Oct. 26.

Sources say the singer may have been dead for as long as six hours before a security guard found her just before 4 p.m. London time.

That contrasts with an earlier report that Winehouse was still alive when emergency personnel were called to her London flat, but died before she could be transported to the hospital.

A doctor had visited Winehouse the day before her death, The Sun reports, and "had no concerns."

Police sources say there was no sign of drugs in the home. Winehouse had been known to have addiction issues. Her last concert, on June 18 in Belgrade, Serbia, was a disastrous event where the singer slurred through her songs, was booed, and left the stage early, forcing her band to continue playing to meet its contractual obligations.
