Cengiz Han Nuray (July 25, 1977 - c. April 1995) was a teenager who went missing from Santa Cruz, California, in 1995.
A month after he went missing, his headless and badly decomposed body was found in the water at Alisomar State Beach in Pacific Grove, California. His cause of death could not be determined, but there was no evidence of foul play.
He was identified via DNA testing in December 2014. Nuray was known to be following the Grateful Dead before his disappearance, and he was considered an identity for the then-unidentified Grateful Doe before being ruled out. Grateful Doe was later identified as Jason Callahan.
