The autopsy conducted today on Amy Winehouse was inconclusive in determining the cause of the singer's death and officials now await the results of toxicology tests, Sky News reported.

The toxicology results could take between two to four weeks to come out, the report said.

A coroner's officer at St. Pancras Coroner's Court told the hearing that Winehouse's body "was identified by her family here at St. Pancras [Monday] morning."

The young singer had been troubled by alcohol and drug problems throughout her career, but police reiterated Monday that it was too early to speculate on a cause of death. "The scene was investigated by police and determined non-suspicious," the coroner's officer said.

Earlier Monday, the Grammy-winning singer's father told fans gathered outside her London home that he was "devastated and speechless" over her death.

"Amy was about one thing, and that was love," he told mourners. "Her whole life was devoted to her family and her friends and to you guys [fans], as well. We're devastated, and I'm speechless, but thanks for coming."

The star's grief-stricken mother was in tears as she looked at the tributes and took pictures of them on her cell phone.

The singer was found dead at her North London home Saturday. Paramedics were called to the soul singer's house Saturday afternoon, but she was said to be "beyond help" and was pronounced dead at the scene.
