Mariott

Boston Police Commissioner Ed Davis says Philip Markoff, 22, of Quincy, was today charged with the murder of Julissa Brisman at the Marriott and the attack a few days earlier on another woman at the Westin.

In a press conference with Davis, Suffolk County DA Dan Conley said authorities are looking for additional victims and urged anybody who'd been attacked after placing a Craigslist ad to contact police. He added:

Our top priority is holding Philip Markoff accountable. He's a predator.

Markoff, a second-year student at the Boston University School of Medicine, was stopped today around 4 p.m. on I-95 in Walpole. Conley said that in addition to old-fashioned police work, officials were able to trace IP numbers to specific physical locations. Boston Police had earlier released surveillance photos showing the suspect using a handheld device after allegedly murdering Brisman, who came up from New York City to offer massages advertised on Craigslist.

Markoff will be arraigned tomorrow in Boston Municipal Court for Brisman's murder and on charges of armed robbery and kidnapping for the April 10 incident at the Westin. Warwick, RI, police say a similar attack occurred two days after Brisman's murder in a Holiday Inn there.

Innocent, etc.
