NYPD Commissioner: No Plans to Interview Mary-Kate Olsen on Ledger's Death

NEW YORK – Police Commissioner Ray Kelly says Mary-Kate Olsen will not be questioned by detectives about Heath Ledger's death.

"There's absolutely no indication investigators were going to speak to Mary-Kate Olsen," Kelly said at a news conference Sunday, echoing previous statements by police officials. "They determined that they had all the info needed from witnesses who were on scene: That's the cleaning woman, the masseuse."

Ledger's masseuse, Diana Wolozin, found his body Tuesday in his Manhattan apartment. She had an appointment with Ledger, who starred in "Brokeback Mountain" and other films.

Police have said Wolozin made three calls to Olsen before dialing 911 for help, then phoned the 21-year-old actress a fourth time after paramedics arrived.

At some point during the calls, Olsen, who was in California, summoned her personal security guards to the apartment to help, police have said.

Olsen hasn't spoken publicly about the calls. She has only said: "Heath was a friend. His death is a tragic loss. My thoughts are with his family during this very difficult time."

The cause of Ledger's death will not be known for at least a week, after medical examiners complete toxicology tests. Police have no plans to charge Wolozin; state regulators could discipline her if it turns out she did not have the proper license to practice massage therapy.

Authorities suspect a possible drug overdose, but nothing conclusive has been determined. Several prescription drugs were found in the Manhattan apartment where Ledger's body was found.
