Kate Coe writes the definitive piece:
IN 2001, THERESA DUNCAN was on top of the world. She had a two-picture deal with Fox Searchlight, and came to Los Angeles confident in her ability to conquer Hollywood. In July 2007, she was dead by her own hand, having washed down an overdose of Tylenol PM with bourbon in her Greenwich Village apartment. New York police say her handwritten note indicated she was at peace with her decision.
News of her suicide spread on the Internet, where she had gained a small but devoted audience as a blogger. A week after her suicide, her longtime romantic partner Jeremy Blake, 35, went missing, his clothes and wallet found on the Atlantic shore at Far Rockaway with a note implying he had walked into the sea.
Online conspiracy theorists quickly repeated Duncan’s accounts of being harassed by mysterious forces, including the Church of Scientology.Others saw a twinship with poet Sarah Hannah, herself a recent suicide, and still others saw parallels to an elaborate alternate reality game. Experts, some of whom had never met her, weighed in on everything from her mental state to her sexiness.
