Heath Ledger investigation closed

The US Attorney’s Office official investigation into Heath Ledger’s death has been closed without any charges being filed.

After Heath – who had a two-year-old daughter with former fiancee Michelle Williams – died of accidental prescription drugs overdose in January, officials wanted to determine where he had obtained powerful painkillers Oxycontin and Vicodin – two drugs for which he had no prescription.

Despite reports Heath’s close friend Mary-Kate Olsen – who was subpoenaed by a federal grand jury on 23 April – would be forced to involve herself in the investigation, the probe has now been closed without the subpoena being enforced.

When Mary-Kate – who was the first person Heath’s masseuse called after she found him dead in his New York apartment – was issued with the subpoena, her attorney began negotiating with authorities, and was said to be trying to get the 22-year-old star immunity from prosecution before she would testify in the case.

He released a statement saying: “Ms Olsen had nothing to do with any drugs found and has already provided relevant information for the investigation.”

A coroner’s report showed Heath died of an accidental overdose of prescription drugs for pain, anxiety and sleep.
