Heath Ledger’s death is still a question mark to us all. The NYPD already stopped their investigation on the actor’s death. The Federal Drug Enforcement Agency on the other hand is firm in finding out where Ledger might have acquired the prescription drugs that led to his fatal overdose in January. In their inquiry, the DEA issued a subpoena for Mary-Kate Olsen requiring her to testify in front of a grand jury. Mary-Kate got involved in the issue when the masseuse who found Ledger’s body discovered three phone calls made to Mary-Kate Olsen before the actor died. Recently, controversy arose when Mary-Kate refused to be interviewed by the DEA unless they give her immunity from possible prosecution. This gave rise to rumors that she might have something to do with Ledger’s death!

To stop the rumors, Mary-Kate’s lawyer issued a statement saying that his client “had nothing whatsoever to do with the drugs found in Heath Ledgers home or his body, and she does not know where he obtained them.” She has not been granted the immunity that she seeks, thus she will testify before a grand jury in a private and closed proceeding. She is not allowed to have her lawyer with her during that time. Though she has been served the subpoena, there’s no date as to when she will be called to testify.
