Timeline of Heath Ledger's final moments

In an emergency, call ANYONE BUT MARY-KATE OLSEN. JUST AN OPINION.
Honestly, "slow adults" have been taught to dial 911 in case of emergency. Stick with the plan.

At 2:45 p.m., a masseuse named Diana Wolozin showed up for her massage appointment with Ledger, who didn't answer when she knocked on his door.
She then tried to call him on his cell phone, but again got no response. She went into the bedroom, set up her massage table and again tried to wake Ledger.
Wolozin told police that Ledger was cold to the touch, but she just assumed he was unconscious. She proceeded to grab his cell phone and call Mary Kate Olsen, whose number is programmed into the phone. Wolozin knew that Olsen and Ledger were friends, and she asked Olsen for advice on what she should do next.
Olsen, who also lives in Manhattan but was in California at the time, responded by saying she would send over her private security guards to help deal with the situation. In the ensuing moments, Wolozin realized that Ledger might be dead, and called 911.
The emergency operator provided Wolozin directions on how to do CPR, but it was too late.
Paramedics arrived minutes later - at about the same time as Olsen's security guards.
