Mary-Kate To Be Subpoenaed In Ledger Investigation

NEW YORK, New York -- As the investigation surrounding Heath Ledger's accidental overdose continues, the federal Drug Enforcement Administration office in New York has confirmed to Access Hollywood that they have issued a subpoena that would force Mary-Kate Olsen to testify in front of a grand jury. Five medications were found in Heath's body at the time of his death, according to the DEA, three of which he'd obtained via doctors in Texas and Los Angeles. At the center of the investigation is how he acquired Oxycontin and Vicodin without a legal prescription. (link)
