Med Student Suspected as 'Craigslist Killer'

A Boston University med student was arraigned today in the slaying of a woman at a hotel last week and an earlier attack on another woman. Both victims had advertised personal services on Craigslist.

On Monday, police arrested Philip Markoff, 22, for the murder of Julissa Brisman, 26. Brisman offered massages via Craigslist and was found dead in her hotel room at the Boston Marriott Copley Place on April 14.

The first "Craigslist Killer" victim was said to be a 29-year-old exotic dancer. She was robbed of her credit card and $800 in cash on April 10 from a room at a different hotel.

Suffolk District Attorney Daniel Conley told reporters Markoff was "a predator who may have attacked other women he met through similar Craigslist ads." He added, "There may be other victims out there with a similar m.o., and if there are, we want to help you." The arrest came after police released surveillance footage of a "person of interest" leaving the hotels -- which elicited hundreds of tips.

Markoff's fiancée, Megan McAllister, 25, wrote an email to the Boston Herald, saying, "Philip is a beautiful man inside and out. He is intelligent, loyal and the best fiancé a woman could ask for. He would not hurt a fly." The couple met while working as volunteers in a hospital emergency room and are due to marry this August.
