The family of Amy Winehouse is set to hold a private funeral Tuesday for the British singer, who was found dead Saturday inside her home.

A family spokesman said Winehouse will be buried in a private ceremony for family and close friends.

London police said Monday an autopsy failed to determine how the 27-year-old died. They are calling her death unexplained, but say it is not suspicious.

Forensic experts will now carry out toxicology tests, whose results could take several weeks.

Winehouse's parents stepped outside the singer's London home Monday to thank gathered mourners and fans for their support.

The singer led a tumultuous life, struggling with drugs, alcohol and abusive relationships even while critics and fans hailed her as a masterful blues and jazz artist. She gained worldwide success with her Grammy award-winning second album Back to Black.

But Winehouse also struggled to keep her career on track. She cancelled her European tour last month after an audience in Serbia booed her off the stage when she appeared to be disorientated and incoherent.
