Philip Markoff, a 22 year-old medical student, had been arrested by Boston Police on suspicion of being the “Craigslist Killer.” The cops had been following Philip after he was identified as the man in the footage taken near the crime scenes and released in an appeal for help.

Philip will be charged in Boston Municipal Court with the murder of masseuse Julissa Brisman, who was shot in a Boston hotel last Tuesday, but he is also believed to be involved kidnapping and robbery of at least two other escorts who advertised their services on Craigslist.

“He is a predator,” said Boston Police Commissioner Ed Davis. “There may be other victims out there, and we want to help you.”

Philip is engaged to be married with a fellow med student, Megan McAllister, and the couple has a web page dedicated to their wedding later this year.
