NEW YORK (AP) – The woman who discovered a lifeless Heath Ledger spent nine minutes making three calls to Mary-Kate Olsen before she dialed 911 for help, police said Thursday. She called the “Full House” actress a fourth time after paramedics arrived.

The details about the calls do not have any significant bearing on the investigation because authorities believe Ledger had been dead and have ruled out foul play. But they paint a more precise picture of the bizarre series of events surrounding the Australian-born actor’s final moments.

The woman, Diana Wolozin, had an appointment to give Ledger a massage Tuesday afternoon. Police originally said she made two calls to Olsen in seeking her help about what to do, but revised it to four after taking a closer look at Ledger’s phone records.

Wolozin apparently knew both Ledger and Olsen and that they were friends; all the calls were made from Ledger’s cell phone.

At 1 p.m. Tuesday, Ledger’s housekeeper went into his bedroom to change a light bulb, saw him sleeping and heard what she thought was snoring. Wolozin showed up for Ledger’s appointment at about 2:45 p.m. and knocked on his door and called his cell phone at 3 p.m. to wake him up.

After setting up her massage table, she tried to wake Ledger and realized something was wrong.

At 3:17 p.m., she made a call to the Olsen twin that lasted 49 seconds. At 3:20 p.m., she made another call – this one lasting a minute and 39 seconds. She made a third call at 3:24, which lasted 21 seconds.

She called 911 at 3:26 p.m.

Before this frenzy, Olsen, who was in California, summoned her personal security guards to the apartment to help with the situation, the NYPD said.

Paramedics arrived at 3:33 p.m., and actually went up in the elevator to the apartment with Olsen’s security guards. Paramedics did not allow the security guards into the bedroom where Ledger died, and they declared him dead at 3:36 p.m. – 19 minutes after the first call to Olsen.

Wolozin called Olsen a final time at 3:34 p.m. The duration of that call was unknown.
