According to new reports, Philip Markoff, AKA the Craigslist Killer, accused of murdering 26-year-old masseuse Julissa Brisman, also went after biological men. An anonymous source in Boston told NBC News "I posted an ad on Craigslist under 'males for transsexuals' ... "That's where he found me." Though the two never met, Markoff replied to the tranny delight using the e-mail address [email protected], saying, "I am a 22 y/o grad student. 6'3", 205, good build, blond/blue eyes ... let me know what else you want to see or know about me." Markoff also send the source explicit photos of himself, which helped him identify Markoff to police. Markoff, a deeply in debt medical student with a Scott Peterson-like charm, is also suspected of robbing a woman in a Boston hotel prior to Brisman's murder.
