Vanished SI mom on cam

Turkish police investigating the disappearance of a Staten Island woman are poring over security footage that shows her casually walking around and eating at a mall near her hostel just before she vanished.

Amateur photographer and married mom of two Sarai Sierra, 33, has been missing since Jan. 21, the day before she was supposed to fly home from Istanbul to New York.

Her friend, Maggie Rodriguez, was supposed to accompany her on the picture-taking trip but told The Post yesterday that she backed out at the last minute because she didn’t have enough money to go. She said she has been wrestling with the guilt ever since.

“It hurts quite a bit to know whatever happened wouldn’t have happened if there were two of us together,” Rodriguez said.

Sierra’s husband, Steven, and her brother, David Jimenez, flew to Istanbul to meet with police and diplomatic officials.

Sierra last spoke to her family on Jan. 21. She told them she was cutting her trip short to surprise her sons, ages 9 and 11.
