Turkish police have identified and are looking for a man suspected of killing American tourist Sarai Sierra, whose body was found earlier this month, CNN affiliate CNN Turk reported Thursday.

Police are looking for the suspect, identified only as "Ziya T," in the southern province of Hatay, where his family lives, CNN Turk reported.

Sierra, of New York, traveled alone to Istanbul on January 7. She was reported missing after she did not arrive on a return flight January 22, and Turkish police found her body near ancient stone walls in Istanbul's Sarayburnu district this month.
