When Manhattan model and masseuse Julissa Brisman went to meet a client at a luxury Boston hotel, she thought she'd be leaving the hotel with enough money to buy her little sister's school books. But Philip Markoff, the 22-year old med student who hired Brisman on Craigslist, had different plans. On April 14, 2009, guests notified management of a woman screaming on the 20th floor, and Brisman was found in a pool of blood, with several bullet wounds to her torso and a plastic restraint around her wrist. The hotel's surveillance cameras captured Markoff's image and an additional tip-off led police to follow him for several days prior to his arrest. Markoff is believed to have also assualted and robbed several other women, including an armed robbery and kidnapping of a prostitute who was tied up at another Boston hotel on April 10 and the assault of an exotic dancer in Rhode Island on April 16, both of which bear remarkable similarity to the Brisman murder. Markoff was arrested by Boston police on April 21 and is being held without bail. The investigation is ongoing.
