The Feds have interviewed about 23,000 people in connection with the accidental drug overdose that resulted in Heath Ledgers death. Investigaters say that everyone has been extremely cooperative except for the troll-girl Mary-Kate Olsen.

The New York Post reports that MK “has refused to speak” and her lawyer, Michael Miller, claims she won’t be interviewed “unless she gets immunity, exercising her constitutional rights.”

The fuzz want to know where the un-prescribed OxyContin involved in Heath’s death came from and since MK was the first one called they assume she knows something. They know troll-girl could lead them to the source and possibly to some major drug players.

There is also buzz that the Oxy came from a “a friend” and the bottle with that “friends” name on it was removed from the apartment before the police arrived. Do you think little trolly snuck in there and got her drugs out before the coppers got there? It totally makes sense. Maybe the Feds will figure out a way to prove it without her help and prosecute her annoying ass to the fullest extent of the law. Or at least take away those heinous flannel she wears all the time.
