The agency said Sierra was found with a head wound and a blanket near her body. She was wearing jeans, a jumper and a jacket. She also had still had her earrings and a bracelet. 

Police said she suffered a fatal blow to the head.

Turkish authorities finished an autopsy Monday and submitted DNA samples to a crime lab for testing. Police were still scouring the area where the body was found for clues with the help of sniffer dogs, the state-run Anadolu Agency reported.

Sierra, 33, went missing Jan. 21 while on a solo vacation in Istanbul. She left for Istanbul to explore her photography hobby and was in regular contact with friends and relatives during the trip. She reportedly told them she would visit Galata Bridge, which spans Istanbul's Golden Horn waterway, to take photos.

The body was found not far from the bridge.

The Milliyet newspaper said a forensic medicine lab will examine samples from Sierra's fingernails as well as hair and other samples from a blanket found near her body. It said some nail scrapings suggest she may have tried to fight off her attacker.

More than a dozen people were questioned in the case but most of them have been released, Milliyet reported. It said three people were still being held for questioning.
