The search for a missing Staten Island mother is intensifying in Turkey.
Police in Istanbul have released security camera footage of Sarai Sierra.
It shows her eating alone in the food court of a mall near the hostel where she was staying.
Her family says she has been there since January 7, but has not been heard from in over a week.
Sierra, a 33-year-old amateur photographer and mother of two, was supposed to come home last Tuesday, but the airline says she never got on the plane.
Meanwhile, her husband, who arrived in Istanbul on Monday along with her brother, has been interviewed by police in hopes of aiding in the search.
