Summary based on the NamUs case record (MP78961) and 3 other sources
Long Zhao, a 36-year-old man, was last seen on May 31, 2001, in Alhambra, California. At the time of his disappearance, Zhao stood 5'9" tall, weighed around 140 pounds, and had black hair and brown eyes. He also had a distinctive tattoo of a phoenix on his right arm.

Despite his disappearance being reported, few details are available regarding the circumstances surrounding it. Zhao has not been heard from since that day, and his case remains unsolved. His status is classified as "voluntary missing," suggesting the possibility that his disappearance may have been intentional, though there has been no confirmation or further evidence to clarify his situation.

Authorities have not disclosed much information about what Zhao was last wearing or carrying at the time of his disappearance. His case is still being investigated by the Alhambra Police Department, and anyone with relevant information is encouraged to come forward to assist in resolving the case.

Zhao's disappearance remains a mystery more than two decades later.
