Mary-Kate Olsen Had 'Nothing To Do With' Heath Ledger's Drugs: Lawyer

'We have provided the government with relevant information," lawyer says.

Mary-Kate Olsen's lawyer issued a statement Monday (August 4) claiming that the actress had no involvement with the drugs that killed Heath Ledger and has already cooperated with police, according to The New York Post and other outlets reported Monday morning that Olsen had declined to speak with investigators unless she was granted immunity from prosecution.

"Despite tabloid speculation, Mary-Kate Olsen had nothing whatsoever to do with the drugs found in Heath Ledger's home or his body, and she does not know where he obtained them," Olsen lawyer Michael C. Miller told People in a statement.

The Post had speculated broadly about the source of the OxyContin found in Ledger's system when he died, and Miller denied any connection to Olsen in his statement.

"Regarding the government's investigation, at Ms. Olsen's request, we have provided the government with relevant information including facts in the chronology of events surrounding Mr. Ledger's death and the fact that Ms. Olsen does not know the source of the drugs Mr. Ledger consumed," the statement continued. "We don't know the source of the information being quoted in the media regarding the government's inquiry, but these descriptions are incomplete and inaccurate."

The actress was the first person Ledger's housekeeper called after his masseuse found the actor dead from an accidental overdose in his SoHo apartment January 22. Federal investigators have already talked to many people connected to "The Dark Knight" star, including his doctors, the masseuse, his family and actress Michelle Williams, who is the mother of his two-year-old daughter, Matilda.
