A former Boston medical student charged with killing a masseuse he met on Craigslist has lost a bid for an investigation into media leaks he claimed may have tainted the grand jury that indicted him.
An attorney for Philip Markoff last month asked a judge in Boston to order prosecutors to prove that media leaks didn't influence the grand jury.
Attorney John Salsberg cited news articles that included leaked evidence and possible motives for the killing of New York masseuse Julissa Brisman and the robbery of a prostitute Markoff allegedly met through the erotic services section of Craigslist.
But Judge Frank Gaziano ruled the defense did not show that grand jurors were influenced by bias or prejudice. He also noted grand jurors are not banned from reading news reports.
Prosecutors say Markoff left a trail linking him to the attacks including his fingerprints on the ties allegedly used to bind the women and on the identification used under another man's name to buy the 9 mm weapon that killed Brisman.
The weapon was found in a hollowed-out copy of Gray's Anatomy in the Quincy apartment Markoff shared with his then-fiancee, Megan McAllister, prosecutors said. McAllister has since called off plans for their August wedding in New Jersey.
They also say Markoff was seen on surveillance video coming and going from the Boston hotels around the times of the attacks.
