Heath Ledger HLEDGERVEN012208_011.jpg Last night was an eventful night of revelations relating to Heath Ledger's tragic passing on Tuesday - here's a quick roundup:

- First off, PageSix.com contacted possibly the last person to speak to Ledger - and he says Heath's last request was to wake him up!

According to reports, Ledger's final phone call was from his director friend Shekhar Kapur, who'd directed Heath on The Four Feathers, when Kapur called to set up a meeting for the following day.

Apparently, Ledger's parting words were a plea for Kapur to "call him in the morning and wake him ... I tried. Little did I know that his soul had already left his body."

- Meanwhile, Heath's family is taking to the airwaves to defend the fallen actor's sense of responsibility.

During an interview with CBS' Early Show this morning, Ledger's uncle was explicit in his belief that Heath would have never done something so "irresponsible" on purpose.

"It just wouldn't come into the equation at all," Heath's uncle Haydn told viewers.

Haydn and Heath's other uncle Mike also deflected questions about their famous nephew's alleged depression, claiming that the subject was better left to Heath's parents.

"It's certainly, as far as we're concerned, a tragic accident and death," Haydn Ledger said.

- And finally, it seems that Haydn's claims of an accidental death are true - tests for drugs on the now-infamous rolled up $20 bill came back clean!

E! News is reporting that the rolled-up bill found in close proximity to Ledger's body came back negative when tested by police for illicit substances, effectively putting an end to any suspicions that the actor had snorted any drugs before his death.

Police attention is currently focused on the prescription medicines - six in all, including sleeping aids, anti-anxeity drugs, and an unidentified antihistamine - which were found in close proximity to Ledger's body.

Us, meanwhile, confirms that all six prescriptions were in Ledger's name - and stresses that Ledger had recently spoken about coping with insomnia.

So what do you think now that more facts are in? Was Heath's death a tragic accident? Or might there be more to this story that we simply haven't heard yet?
