Details surrounding Amy Winehouse's final hours became clearer as her family and friends laid her to rest today.
Kelly Osbourne and Mark Ronson were among the famous friends that joined Winehouse's family and loved ones at London's Edgwarebury Cemetery earlier today. Winehouse will be cremated following the service.
Winehouse's U.K.-based representative, Chris Goodman, told Britain's Daily Mail that her father gave a touching eulogy at today's ceremony.
"Mitch's last words to Amy in his eulogy were 'Goodnight my angel,'" Goodman said. "Sleep tight. Mummy and Daddy love you ever so much."
Reg Traviss, Winehouse's most recent boyfriend, attended the funeral and spoke to Britain's Sun newspaper about the singer's death, saying "I have lost my darling who I loved very much." Blake Fielder-Civil, Winehouse's ex-husband, was not in attendence. He's currently serving a 32 month jail sentence.
Rabbi Frank Hellner officiated the Jewish service in which family and friends sang Winehouse's favorite song, Carole King's "So Far Away." Afterwards, Winehouse's body was taken to Golders Green Crematorium, where her grandmother was cremated. Her family will sit shiva for two days in mourning.
What Killed Amy Winehouse?
U.K. officials began an autopsy Monday to determine what killed the 27-year-old singer, who was found dead in her home in London's Camden district Saturday. They are awaiting the results of a toxicology test, which are expected in two to four weeks. No formal cause of death has been established, and officials reportedly have found no paraphernalia or sign of drugs in Winehouse's home.
Winehouse's official cause of death will be released in October.
On Monday, Goodman revealed that a bodyguard hired to watch the singer was the first person to discover her death.
"She was in her bedroom after saying she wanted to sleep, and when he went to wake her, he found she wasn't breathing," he told the Sun. "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."
The Sun also reported that Winehouse had seen a doctor Friday night as part of a routine series of checkups, given her history of drug and alcohol abuse. The doctor saw nothing wrong.
The Grammy-winning singer was literally rocking out the night before she died, according to People magazine,
"We know that she was well enough to be playing drums well into Friday night," said Julie Dam, People's assistant managing editor. "We spoke to neighbors who said she was usually so quiet. It's worth noting that she was making a lot of noise that night."
But Winehouse's clean bill of health and activity prior to her death might have masked underlying problems from years of substance abuse that eventually killed her.
"She may have had asthma and emphysema because of her smoking," said Dr. Eric Braverman, an addiction specialist and author of the book "The Edge Effect." "From that, you can have a terrible respiratory arrest. You can have a seizure. Your lungs can choke off your trachea. It happens in asthmatics a lot."
Respiratory conditions might not have been picked up by Winehouse's physician.
"If you have a pulmonary disease, you need a lung function test, not a stethoscope," Braverman said. "So a simple physical that tells you you have a clean bill of health doesn't say much."
Winehouse's father told reporters in 2008 that she had been diagnosed with early-stage emphysema. She was also vocal about her struggles with eating disorders, which could have played a part in her death, too.
"You can also suffer cardiac arrhythmia from dieting and not eating properly," Braverman said. "Even panic attacks in her state can constrict the lungs and bring on death."
