Turkish police reportedly fail to find DNA match in murder of New York mom The investigation into what happened to a Staten Island woman murdered in Turkey took another twist, as Turkish media reported that none of the DNA taken from 22 suspects matches the DNA found near her body. A Turkish newspaper also reported that the family of 33-year-old Sarai Sierra knew she was cheating on her husband, the New York Post reported. Turkish newspaper Per Vatan revealed that Sierra's brother allegedly sent the mother of two a Facebook message saying, "If you are going to cheat on him, why don't you just get out of his life," the Post reported. The message was allegedly sent before she went missing. She was found beaten to death in a seedy area of Istanbul. The newspaper report comes after a man being questioned by Turkish authorities in the murder of Sierra that he had a sexual relationship with her. The Turkish man, identified only as "Taylan," gave DNA and sperm samples to police, according to Vatan. The man allegedly told investigators he had a consensual sexual relationship with Sierra before she was last seen on Jan. 21, according to the paper. Sierra's friend Magdalena Rodriguez told FoxNews.com she doesn't believe the man's claim. Click for more from The NYPost.
