Eight years after his death, Heath Ledger's dad has revealed the actor's heartbreaking final conversation. "The last conversation [Heath's sister] Kate had with him was this discussion about his medications and she warned him, 'You can’t mix drugs that you don’t know anything about,'" dad Kim Ledger tells Australia's News Network. "He said ‘Katie, Katie, I’ll be fine.' Well, that’s a cavalier boy’s answer. It just put his whole system to sleep, I guess." Ledger, 28, had oxycodone, hydrocodone, diazepam, temazepam, alprazolam, and doxylamine in his system when he died.
"It was a one-off thing," says Kim Ledger, who insists his son was not an addict. "That’s what killed us, because he was warned by his sister the night before: ‘You shouldn’t mix what you’re taking for pneumonia with your Ambien.' ... Heath mixed a couple of drugs together with sleeping tablets and he’s gone forever." Ledger adds, though, that his son was feeling the pressure from his hectic work schedule: "Most of Heath’s problems were self-induced. ... He was trying to work and travel and do everything in a short space of time."
