"A Boston city councilor called Monday for an independent investigation of the apparent suicide of a former medical student awaiting trial in the death of a masseuse he met through Craigslist.City Councilor Stephen Murphy said Philip Markoff should not have been able to kill himself while in custody of the Suffolk County sheriff. Markoff was discovered dead, alone in his cell, on Sunday morning. An autopsy was scheduled for Monday, but the Boston Herald, quoting anonymous sources, said the 24-year-old used a pen to cut arteries and covered his head with a plastic bag. The newspaper also reported that he had not been checked all night. ""Regardless of my personal feelings about Philip Markoff, he technically was an inmate awaiting trial, and he was in the care and custody of the Suffolk County Sheriff's Office. He had shown a penchant for doing harm to himself before. You would have thought he would have been under the closest of attention,"" said Murphy, chairman of the council's Public Safety Committee. Murphy said the Boston Police Department and Suffolk County district attorney should expand their investigation of Markoff's death to examine procedures at the Nashua Street jail and other facilities under the jurisdiction of Suffolk County Sheriff Andrea Cabral. An attorney for the family of victim Julissa Brisman says Markoff's death denies a long-awaited opportunity to confront him and hear the details of Brisman's final moments."
