Warwick, R.I.: April 16, 2009
On April 16, 2009, two days after Julissa Brisman's murder, police say the man now dubbed the "Craigslist Killer" had found a new target 60 miles from Boston at a Holiday Inn Express in Warwick, R.I. The following surveillance photos were taken between 10:51 and 10:52 p.m.
On April 16, 2009, a 26-year-old dancer from Las Vegas was tied up by a tall, clean-cut blond man at a Holiday Inn Express, where he tried to rob her, Warwick police said. As with the previous attacks, the woman had advertised her services on Craigslist.
The woman told "48 Hours Mystery" she advertised on Craigslist, offering private lap dances in her hotel room. She said a man who matched the description of the man who attacked the other two women in Boston, pointed a gun at her.
The woman's husband was waiting in the lobby for a signal that everything was OK. When he did not get it, he began calling and headed up to his wife's room, interrupting the gunman, who then ran from the room and down a hallway. Security cameras captured a man, later identified as Philip Markoff, in the stairwell and lobby.
