Turkish police are reportedly seeking a 46-year-old homeless man in the murder of a Staten Island, New York, woman who had been vacationing in Istanbul, a Turkish newspaper reported Thursday. Referred to by police just as Z, the man apparently regularly frequented the part of Istanbul where Sarai Sierra disappeared. They suspect Z may have tried to accost Sierra. He has been missing since her body was found February 2. Sierra’s funeral will be Thursday in Staten Island.
