30-Year Mystery Solved: The Identification of Joseph Louis Serrao Jr.
Forensic tests recently helped identify the remains of a man who went missing in 1998. The man, Joseph Louis Serrao Jr., was originally from Hawaii and had disappeared while in Washington. His family had not heard from him since 1998. In July 2000, human skeletal remains were discovered in a sleeping bag in a remote area of Olympic National Park in Washington. The remains were found with various items, including binoculars, a day hiker pack, and winter gear. Initially, the pathologist estimated the man's age to be between 30 and 50 years old, but his identity remained unknown due to the lack of usable fingerprints and other evidence.
Joseph Serrao was born in December 1960, making him in his late 30s at the time of his death. Despite efforts to identify him, his name remained a mystery until recently. In 2024, an anthropologist submitted a DNA sample to a forensic laboratory, which used forensic genealogy to identify possible family members by 2025. DNA samples from relatives in multiple states, including Hawaii, were compared and matched to the one taken from Serrao's remains. This breakthrough in identification brought closure to the case that had remained unresolved for nearly 30 years.
The National Park Service, along with King County authorities and the laboratory, worked together to solve Serrao's case. The collaboration and persistence of the investigators led to the successful identification of Joseph Serrao Jr. The park service's deputy chief of the criminal investigative division expressed pride in the team's efforts and hoped that the identification would bring closure to Serrao's family after years of uncertainty.
