(CBS/AP) LONDON - Updated 11:51 a.m. EDT
An autopsy is being held to determine the cause of Amy Winehouse's death, but a coroner's official says police have found no suspicious circumstances.
The singer was found dead Saturday at her London home at the age of 27.
A coroner opened and adjourned an inquest into the unexplained death, leaving Winehouse's family free to plan her funeral. A private family service could be held as early as Tuesday.
Police said an autopsy was being held Monday afternoon, and results would be announced later in the day or on Tuesday.
An inquest into the 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.
Duff said a forensic post-mortem was being held, along with histology and toxicology tests, to determine the cause of death. She said "the scene was investigated by police and determined non-suspicious."
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 resume on Oct. 26.
Winehouse's death came after the singer publicly struggled with drug and alcohol abuse for years. Her body was discovered at home by a member of her security team, who called an ambulance. It arrived too late to save her.
Police have said her death is being treated as "unexplained" but not suspicious, and have said speculation that she might have suffered an overdose was inappropriate.
British tabloid The Sun reported Monday that Winehouse may have been dead for hours before she was discovered lying in her bed. Police sources told the paper that there was no sign of drugs in the house.
Sources also told The Sun that Winehouse had seen a doctor on Friday night as part of a series of regular check-ups, and the doctor saw nothing amiss.
