Mystery of remains found inside sleeping bag in Olympic park solved after 26 years
Human remains found in Olympic National Park in 2000 have been identified as Joseph Louis Serrao Jr., a Hawaii native last contacted by family in 1998.
Human remains discovered in a remote section of a Washington state national park more than two decades ago have finally been identified, bringing long-awaited answers about the person's identity.
National Park Service (NPS) officials announced that the remains found in Olympic National Park belong to Joseph Louis Serrao Jr., a Hawaii native whose family last had contact with him in 1998.
"This case remained unresolved for nearly 30 years, but investigators never lost sight of the goal of identifying this individual and finding answers for his family," Debra Flowers, deputy chief of the National Park Service Investigative Services Branch, said in a statement.

"I'm proud of the persistence and collaboration that made this identification possible, and I hope it brings some measure of closure to those who have spent so many years wondering what happened to Joseph."
The case dates back to July 2000, when a researcher discovered skeletal remains inside a sleeping bag in a tent in the Sol Duc River drainage area of Olympic National Park, located on Washington state's Olympic Peninsula.
Investigators also recovered several personal belongings from the campsite, including binoculars, a backpack, a shoulder bag, a folding saw, a blanket and winter clothing, according to reports.

A medical examiner determined the remains likely belonged to a man between the ages of 30 and 50, but authorities were unable to determine his identity.
Evidence collected from the scene was processed by the Washington State Patrol Crime Laboratory, but investigators were unable to obtain usable fingerprints, according to the park service.
Despite years of investigative work, the case remained unsolved.

The breakthrough came decades later when investigators used advanced DNA testing to search for possible relatives.
That effort eventually led authorities to Serrao's family, who confirmed they had not heard from him since 1998.
Investigators later matched DNA samples from family members to the remains, according to NPS.
Family members told investigators that Serrao was originally from Hawaii and had been living in Washington before he disappeared.
