(Cover) - EN Showbiz - Police are reviewing "tens of hours" of security camera footage as they try to piece together Amy Winehouse's final hours.

The singer was found dead in her home in Camden, London, last month. She was 27 and a post-mortem was inconclusive so cause of death won't be known until toxicology tests return in a few weeks.

Amy battled addictions to drink and drugs, but her family insist she was clean when she passed away. Her father Mitch says she gave up alcohol three weeks before she died, with the family believing she either had a seizure or heart attack. Mitch claims she was at home playing drums the evening prior to her death, but other people have said she was out in Camden. Police are now checking CCTV in an effort to find out the truth.

"There are enough cameras in the area to get a picture of her movements," a source told British newspaper The Daily Mirror. "It's a painstaking operation which involves going through tens of hours of footage."

Shortly after Amy died a source claimed she'd bought drugs including ketamine and ecstasy the evening before her passing. Then earlier this week, Tony Azzopardi alleged she'd given him 1,200 to buy cocaine and heroin. He met with police for half an hour yesterday, and is due to be interviewed again today.

Tony first made the claims in a newspaper, explaining he met the singer via her ex-husband Blake Fielder-Civil. He insists he spoke out so the star's family "know the truth".

Mitch, his wife Jane and Amy's brother Alex have decided to take some time out from the spotlight to cope with her death. They are going abroad for ten days to deal with their loss with Amy's partner Reg Traviss who it's understood she was secretly engaged to also taking the trip. It coincides with a family wedding, and the group think getting out of the country is just what they need.

"The family feel they want to grieve properly out of the limelight," a source told British newspaper The Sun. "They will celebrate Amy's life and share their most treasured stories of her."

The group have been seen regularly at Amy's Camden home, where fans have constructed a shrine of candles, pictures, CDs and hand-written notes. Yesterday a portrait of the star measuring 8ft. square was placed there, and while the family love the tributes seeing them has proved tough.

"Being in Camden constantly is proving too painful for them. They need time to themselves," the source explained.
