(Newser) – Mary-Kate Olsen, the first person phoned after a masseuse found Heath Ledger’s body, won't agree to be interviewed by federal investigators without a guarantee of immunity from prosecution, the New York Post reports. The feds have interviewed everyone else they consider connected to the case, including a “nice and cooperative” Michelle Williams—except the Olsen twin.

To compel testimony, feds may seek a grand jury subpoena for Olsen, who sent her bodyguards to Ledger’s loft instead of contacting emergency responders after receiving the call. "Everyone has been very eager to help, saying what a great guy Heath Ledger was, everyone except Mary-Kate, who has refused to speak,” said a source.
