FILE - This Feb. 2, 2013 file photo shows police forensics workers searching for Sarai Sierra, a missing New York City woman, near the remnants of some ancient city walls in low-income district of Sarayburnu in Istanbul, Turkey.  Sierra, a 33-year-old mother of two, went missing while vacationing alone in Istanbul. Her body was discovered Feb. 2 amid the city walls. Recent high-profile attacks on tourists in India, Brazil, Turkey and Mexico have raised questions about personal safety for overseas travel, especially for women. But frequent travelers and those who work in the industry say a few common-sense precautions can go a long way to ensuring personal safety. (AP Photo, file)
