A man suspected of murdering New York model Julissa Brisman in a Marriott Hotel in Boston is now implicated in the armed robbery of two more women. Boston police suspect he met all three women through personal service ads on Craigslist. The 26-year-old Brisman was described by friends as "a really sweet, goofy, energetic kid." She was allegedly found by the man after offering massage services on Craigslist. Police think the killer wanted to rob Brisman when they met at the hotel, until she struggled with him in the doorway and he shot her. Two other women who advertised services on Craigslist have been robbed at gunpoint in the Boston area, leading police to believe the man who killed Brisman was also involved in those robberies. Video from Marriott surveillance cameras after Brisman's murder show a tall, clean-cut, blond man leaving the property.
