A man who died on Mount Si roughly two decades ago remains unknown a year after his remains were found, and King County Sheriff’s officers are asking for the public’s help.

The remains, found June 16, 2015, by two off-trail hikers on Mount Si’s Haystack Rock, were determined to be human by the King County Medical Examiner. After examining the remains, ME staff suggested they are from a Caucasian man, 30 to 60 years old, who was likely between 5’7″ and 6 feet tall.

The sheriff’s office has provided a sketch of what the man may have looked like before his death.

Evidence suggests the remains may be from the mid 90’s. However, no missing persons reports from that era seem to relate to the victim.

No cause of death has been determined.

A pair of tortoise shell glasses, a Swiss Army watch, and an Ortovox shovel were found with the remains. In addition to those items, a green Jansport backpack, and a pair of white Nike high-top tennis shoes size 12, were also located. A black leather wallet was also found with the remains but contained no identification.

If anyone has information on the identity of these remains, they are urged to call the King County Sheriff’s Office, any time, at (206) 296-3311, or send tips to mcutips@kingcounty.gov.
