Another day, another set of updates in the tragic Heath Ledger story.

It seems like the masseuse called Mary-Kate Olsen upon being unable to wake Heath because "she didn't want a media circus," sources tells the New York Post. MK, whom law enforcement officials say she and Heath were dating, said she would send her private security guards there. But before anyone could arrive, she called MK again and screamed, "I think he's dead!" police say. The masseuse then called 911 and the operator told her how to administer CPR. Right after the paramedics arrived and tried to revive him, MK's bodyguard showed up. But at 3:36 p.m., Heath was pronounced dead.

There was no evidence of alcohol use, and no illegal drugs were found in the apartment. However, cops found bottles of six different prescription pills, all in Heath's name -- two for anxiety, two for pain, and two for insomnia. While yesterday's autopsy report was inconclusive, more tests were ordered and will take 10 to 14 days to complete.

Heath's ex-fiancée, Michelle Williams arrived in New York yesterday with their daughter Matilda Rose. They were in Sweden while Michelle was filming the upcoming film Mammoth.
