Who is killing the young male heartthrobs who gained fame in controversial gay-themed movies?

Heath Ledger is found dead of an apparent drug overdose in the bedroom of an apartment in New York City, a week after Brad Renfro is found dead of an apparent drug overdose in the bedroom of his apartment in Los Angeles. Both young actors gained acclaim for roles in controversial gay-themed films-- Ledger in the Academy Award-nominated Brokeback Mountain, and Renfro in Apt Pupil, Bryan Singer's Nazi movie that led to lawsuits by underage male extras who claimed they were forced into nudity. Sadly, They Die in Threes, so we await the next Marilyn Monroe-Anna Nicole style death of a young, talented male actor.
