Human remains found in Olympic National Park 26 years ago have been identified as Joseph Louis Serrao Jr., a man last heard from by his family in 1998. The identification, made in 2025 through DNA and forensic genealogy, closes one of the park’s long-running unidentified-remains cases.

Serrao’s remains were first discovered in July 2000 in a sleeping bag inside a tent in a remote part of the Washington park along the Sol Duc River. Investigators later matched DNA from the remains to samples from relatives reached in multiple states, including Hawaii, where Serrao was originally from.

The identification matters now because it turns a set of bones found in the backcountry into a named man with a family history and a date of disappearance. Serrao was born in December 1960 and would have been in his late 30s when he died, fitting the broad estimate given at the time that the remains belonged to a man between 30 and 50 years old.

Back then, investigators had little to work with. A pathologist in King County said the man had likely died at least six months and up to two years before the remains were found, but usable fingerprints and other concrete evidence were lacking, and the case stalled for decades. Items recovered with the body included binoculars, a day hiker pack, a shoulder bag, a folding saw, a blanket and winter gear, but none produced a quick identification.

The break came in 2024, when an anthropologist with the medical examiner’s office submitted a DNA sample to Othram. By 2025, forensic genealogy pointed investigators toward possible relatives, and family DNA samples were compared with the profile taken from Serrao’s remains. The match gave investigators what they had been missing for nearly 30 years and gave Serrao’s relatives an answer after years of uncertainty.

Debra Flowers said the case had remained unresolved for nearly 30 years, but investigators never lost sight of identifying the man and finding answers for his family. She said she hoped the identification would bring some measure of closure to those who had spent so many years wondering what happened to Joseph.

What remains unresolved is how Serrao died in Olympic National Park. The identification answers who he was, and where the trail ended, but not what led him into that remote stretch of the park in the first place.
