I just googled the most recent article and skimmed it before using it :') my bad!

Here's something better:

On Tuesday, January 22, sometime between 3 and 3:30 a.m., a masseuse found Ledger dead in his loft, on Broome Street in New York’s SoHo. An autopsy would find that his death was accidental, resulting from “the abuse of prescription medications,” according to a spokeswoman for the New York City medical examiner. Among the drugs found in his body were the essential ingredients of Valium, Xanax, Oxycontin, Vicodin, and Restoril—a stew of painkillers, anti-anxiety medication, and sleeping pills. “It’s the combination of the drugs that caused the problem,” said the spokeswoman, “not necessarily too much of any particular drug.”

That explanation notwithstanding, many of Ledger’s friends continue to puzzle over his death, its larger meaning, almost as if they can’t quite let him go. “Everyone has a different view of how he passed away,” says Grennell. “From my perspective, and knowing him as well as I did, and being around him as much as I was, it was a combination of exhaustion, sleeping medication, which was doing less good than it was harm, and perhaps the aftereffects of the flu. I guess his body just stopped breathing.”

Says Gilliam, “He desperately wanted to sleep. And he finally got the big sleep. I don’t know if it was the combination of his tiredness with his emotional state. I wish I had the answer. It really bothers me that I can’t make sense out of it. There was nothing grand or dramatic about it. It just happened. It’s still a big mystery.”

One of the ironies surrounding Ledger’s death is that he wanted to make a movie about Nick Drake, a British singer-songwriter in the depressed Donovan vein, who died in 1974 at the age of 26 and developed a posthumous cult following. During pre-production of The Dark Knight, Ledger had created a music video based on one of Drake’s songs, “Black Eyed Dog.” The eerie part of it is the singer suffered from depression and insomnia, and he died from an overdose of amitriptyline, an antidepressant. Whether it was accidental, as some of his family claims, or a suicide, as the coroner’s report states, remains in dispute.
