Amy Winehouse autopsy planned; Dad thanks fans

An autopsy will be conducted Monday to determine what caused the death of Grammy award-winning singer Amy Winehouse. The 27-year-old was found dead in her London home Saturday after publicly struggling with drug and alcohol abuse for years.

Police have said the cause of her death is being treated as "unexplained" and have said that speculation that she might have suffered an overdose is "inappropriate."

Winehouse's father greeted mourners laying flowers outside her north London home on Monday.

Mitch Winehouse thanked people for coming to leave bouquets, messages and handwritten notes. He also thanked photographers and camera crews covering the event.

"This means so much to my family," he said.

On "The Early Show," CBS News correspondent Anthony Mason reported Winehouse's anti-recovery anthem "Rehab" made the daughter of a taxi driver and pharmacist an international star.

Brian Hiatt, senior writer of Rolling Stone magazine, said, "She really seemed like a rebel in a very old sense. And there was just something so thrilling about her."

In 2008, she became the first British woman to bring home five Grammys in a single night, winning record of the year, song of the year and best new artist. But the demons were already catching up to the diva as her popularity soared and her weight plummeted. Drinking and drug problems made her concert appearances increasingly erratic.

Just this past June, when Winehouse kicked off a European tour in Belgrade, Serbia, she seemed lost, unable to remember her own lyrics. Fans booed her off stage. It would be her last performance. Soon after, her tour was canceled.

In music, a history of tragedy has been written after 27th birthdays. Janis Joplin, Jimi Hendrix, Jim Morrison, and Kurt Cobain all died in their 27th year. Amy Jade Winehouse, a singer who somehow seemed destined to die young, has now joined their sad club.
