Investigators continue to look into what caused Amy Winehouse's death at age 27 on Saturday, even as details emerge about the singer's final hours.
On Sunday, her U.K. representative, Chris Goodman, told TMZ that Winehouse was found alone in her bed by a bodyguard who had been hired to keep an eye on her.
"She was in her bedroom after saying she wanted to sleep, and when he went to wake her he found she wasn't breathing," Goodman said of the troubled star. "He called the emergency services straight away. He was very shocked. At this stage no one knows how she died. She died alone in bed."
Police have called Winehouse's death "unexplained." An autopsy is slated to take place on Monday (July 25), with a funeral likely to follow quickly, within the next day or so, as required by Jewish law. Results of the autopsy are not expected before Tuesday.
Winehouse's father, Mitch, a cab driver-turned-lounge-singer, flew back to England on Sunday in the wake of his daughter's death and visited her Camden apartment on Monday morning. According to BBC News, he thanked her fans, who have gathered in a vigil outside the flat, for their support.
"I can't tell you what this means to us. It really is making this a lot easier for us," he told the gathered mourners. "Amy was about one thing and that was love. Her whole life was devoted to her family and her friends and to you guys as well."
The singer's mother, Janis, and brother, Alex, also visited the site to see the collection of flowers, cards and photos that Winehouse's admirers have left. On Sunday, the family released a statement in which they said, "Our family has been left bereft by the loss of Amy, a wonderful daughter, sister, niece. She leaves a gaping hole in our lives. We are coming together to remember her and we would appreciate some privacy and space at this terrible time."
The Sunday Mirror quoted Janis Winehouse on Sunday saying that her daughter had not been well a day before her death. "She seemed out of it," Janis reportedly told the tabloid. "But her passing so suddenly still hasn't hit me."
England's Daily Telegraph reported that Winehouse was visited at home by her doctor on Friday night, 24 hours before her body was discovered at 4 p.m. on Saturday. Police sources told the paper that no drugs were found in the house and that the security detail had last spoken to her around 10 a.m. on Saturday, when she said she was going to take a rest in her room.
The doctor had reportedly been visiting Winehouse regularly to help her combat the ill effects of her years of drinking and drugging. In 2008, Mitch Winehouse revealed that Amy was suffering from the early stages of the incurable pulmonary ailment emphysema, including scarring in her lungs.
"The doctor was happy with her condition. When he left on Friday night he had no concerns. Less than 24 hours later she was found dead," an unnamed source told The Sun tabloid. "Amy's health has been very fragile and she has been having a series of checkups."
Winehouse's final public appearance was last Wednesday, when she joined her goddaughter, Dionne Bromfield, during a show at the Roundhouse in Camden. Though she didn't sing, Winehouse danced alongside Bromfield and encouraged the audience to buy the teenager's just-released second album, Good for the Soul, which, like her 2009 debut, was released through Winehouse's label, Lioness Records.
Before that, Winehouse had pulled out of a series of European comeback concerts in June after a disastrous gig in Serbia in which she was booed after appearing unsteady and disheveled onstage. She had reportedly completed a stay in alcohol rehab after that tour cancellation and had been under orders not to drink.
On Sunday, dozens of stars, from Lady Gaga and Katy Perry to Rihanna, Russell Brand and Mary J. Blige, paid tribute to Winehouse.
