Meanwhile, speculation is rife. A source cited by The People said that the singer had been seen buying substances, believed to be cocaine, heroin, ecstasy and ketamine in the hours before her death.
She is also believed to have been drinking heavily. This combination of drugs and alcohol may have been fatal for the 27-year-old singer.
“Amy seemed determined to have a big one on Friday night,” the insider said. “She was out in Camden on Friday evening, but seemed determined to carry on the party back at her flat.”
“None of us know who was with her into the early hours of Saturday. But getting out of it was clearly her main priority of the night.”
A police source cited by the Daily Mail revealed that the death was treated as “drink and drugs-related.”
Another friend of the star quoted by the Sunday Mirror said they believed it was a “bad” ecstasy pill mixed with a large amount of alcohol that killed her.
Besides her addictions, Winehouse also suffered from emphysema, a lung disease that causes shortness of breath.
The source said: “It was an ecstasy overdose. She could do cocaine until the cows come home. But this was obviously a dodgy pill.”
According to reports, Winehouse was devastated and “inconsolable” after her split from boyfriend Reg Traviss which took place before she checked herself into The Priory rehabilitation clinic in May.
Traviss had previously turned down a marriage proposal from the star and, according to friends, he was desperate to help the singer fight her demons. When he realized he couldn’t get her to change, he ended the relationship.
Amy’s devastated mother Janis admitted that her daughter’s death was “only a matter of time”. She had seen her daughter for the last time just 24 hours before she died.
“She seemed out of it. But her passing so suddenly still hasn’t hit me,” she said.
As they kissed goodbye Amy told her, “I love you, Mum”.
“They are the words I will always treasure and always remember Amy by”, Janis said.
Winehouse’s father Mitch, who was on a jazz tour in New York when he learned of his daughter’s death, returned to the UK.
He said: “I’m coming home. I have to be with Amy. I can’t crack up for her sake. My family need me.”
