Could Mary-Kate Olsen be responsible for Heath Ledger's death? I found this on the msn news page...
A US law enforcement official says federal investigators want to question actress Mary Kate Olsen about how Heath Ledger got two painkillers that contributed to his overdose death. But the official says the star is not talking. Olsen's lawyer has twice refused requests to have her sit down with investigators probing the death of Ledger. The official confirmed a report that Olsen - a close friend of Ledger who learned about the 28-year-old Australian actor's death in a frantic phone call from a masseuse - wants a promise of immunity before she speaks to the Drug Enforcement Administration (DEA). The activity demonstrates that federal authorities are still actively trying to find out how Ledger got some of the drugs that killed him.
DEA investigators suspect the painkillers oxycodone and hydrocodone found in his system were obtained with fake prescriptions or other illegal sources, the official said. Oxycodone is sold as OxyContin and hydrocodone as Vicodin. The other drugs that resulted in what the medical examiner called "acute intoxication", including anti-anxiety and sleeping pills, were prescribed legally by doctors in California and Texas, the official said.
Authorities have obtained a subpoena that could force Olsen to appear before a grand jury if negotiations with her lawyer fail, the official said. Other potential witnesses all have answered questions voluntarily, including doctors, Ledger's ex-girlfriend Michelle Williams and anyone who was in his apartment around the time of his death, the official added.
