Blood on the shirt of a New York mom murdered in Istanbul and skin found under her fingertips allegedly matches the DNA of a homeless man running from Turkish police.
The 33-year-old married mother of two was traveling alone for two weeks when she disappeared on Jan. 21, the day before she was supposed to fly home.
Ziya T was identified early on as a possible suspect. Witnesses claimed he was often in the neighborhood where Sierra was found. He was covered in dirt and had scratches on his arms the day she vanished, according to media reports.
He fled Istanbul and popped up 200 miles east of Istanbul in Karabuk where he has family. Relatives told police he stayed there for three days before announcing that he was headed to the Hatay region near the Syrian border.
A hair found in the bed he slept in allegedly matched the DNA evidence left behind by Sierra's killer, according to the New York Post.
