Police detain suspect in Boston Craigslist murder

Boston's police commissioner says a 22-year-old man has been arrested in the killing in a luxury hotel last week of a woman who advertised massage services on Craigslist.

Commissioner Ed Davis said yesterday that Phil Markoff was arrested after being stopped in south of Boston on Interstate 95 in Walpole.

Davis says authorities had the Boston University student under surveillance "for days" before arresting him.

Markoff is charged with killing Julissa Brisman, 29, who was found dead last Tuesday at the Boston Marriott Copley Place. Police say the New York City woman advertised massage services on Craigslist, the popular online classified ads site, and had a massage table set up in the room where she was shot.

Markoff is scheduled to appear at Boston Municipal Court today.
