Police in New England released new surveillance photos of the so-called "Craigslist Killer," as they continue to hunt the man linked to at least two robbery cases and one death linked to the Web site.

Police in Warwick, R.I., released the pictures Monday in their investigation of another robbery at a Holiday Inn Express Hotel there on Thursday. On Tuesday, the body of Julissa Brisman was found in a room at the Boston Marriot Copley Place. She was shot multiple times in the torso during a robbery and pronounced dead at a nearby hospital.

The same man was photographed Friday at the Westin Hotel in Boston, where a 29-year-old Las Vegas woman was found bound and robbed, police said.

Boston police are investigating more than 150 tips about Brisman's murder.

Brisman, of New York City, advertised massage services on Craigslist and had a massage table set up in the room where she was shot Tuesday. The woman attacked in Warwick advertised lap dances on Craigslist. She was held at gunpoint before her husband entered the room and her attacker fled.

Boston police haven't explicitly said the same man committed both crimes, though the suspects have similar descriptions. They cite only "a strong connection" in the cases.

Investigators from Boston and Warwick continue to work closely together following up on tips and reviewing crime scene evidence, MyFOXBoston.com reported.
