Authorities are withholding the precise cause of death for Philip Markoff following an autopsy on the former medical student accused of killing a masseuse he met through Craigslist.
The Suffolk County district attorney's office said Monday the medical examiner's office was still awaiting the results of specialized tests. They have said Markoff apparently took his own life. He was found dead Sunday in his jail cell.
Meanwhile, the county sheriff says a Boston city councilor is trying to score publicity for his election campaign by seeking an independent investigation of jailhouse procedures.
Suffolk County Sheriff Andrea Cabral says City Councilor Stephen Murphy "persists in talking about things about which he knows nothing." Murphy is running for state treasurer.
Markoff was to stand trial in March in the 2009 murder of Julissa Brisman of New York City.
