Med student held without bail in Craigslist death

Prosecutors said Tuesday they found a semiautomatic weapon at the home of a Boston medical student who has been ordered held without bail on charges he shot to death a masseuse he had lured to a hotel through Craigslist.

Philip Markoff said nothing during the brief hearing in Boston Municipal Court.

Authorities said they followed a computer trail to Markoff, linking an account used to set up appointments on Craigslist, with two women who were attacked, to his address in Quincy.

They say a search of his home found the gun, ammunition and materials exactly matching those used in an attack on another masseuse in a Boston hotel.

Markoff is charged with murder in the death of Julissa Brisman of New York City and kidnapping and armed robbery in the other assault.

The second-year Boston University medical student lives with his fiance, who claims police have the wrong man.

“He could not hurt a fly,” Megan McAllister said in an e-mail to ABC’s “Good Morning America.” “All I have to say is Philip is a beautiful person, inside and out,” she said in the e-mail read on Tuesday’s program.

Markoff’s attorney, John Salsberg, did not immediately comment.

Authorities have said there could be more victims.

“Our top priority is holding Philip Markoff accountable. He’s a predator,” Suffolk District Attorney Daniel Conley said Monday night in announcing Markoff’s arrest earlier in the day during a traffic stop south of Boston.
