The story of the American woman missing in Istanbul took a dark turn Saturday when Turkish authorities confirmed her dead. Sarai Sierra's body was discovered near an ancient city wall in a low-income area where she appeared to have been the victim of a stabbing. Nine people have already been arrested in connection with her death, according to a Turkish news agency. The 33-year-old Staten Island-native had been vacationing alone when she went missing. In security footage obtained by police, she's seen walking around a mall on January 20—one day before she was scheduled to fly home. She leaves behind a husband and two kids.
