Andrew Jonathon Zalcberg, 27, was last seen on December 29, 1997, in Sedro-Woolley, Skagit County, Washington. He was described as a white male, blond or strawberry-blond hair, blue eyes, 5 feet 9 inches and about 145 pounds. At the time he disappeared he was believed to have left a remote location on foot and may have intended to travel to Colorado, though there is no evidence he ever arrived there.

In 2008 a femur bone was found in a creek bed in the general area where Zalcberg was last seen; DNA confirmed the bone was his. No other remains have been located. That single discovery ended the hope of finding him alive but left the circumstances of his death unresolved because investigators lack additional remains or other evidence to explain what happened after he departed on foot.

The Skagit County Sheriff’s Office remains the investigating agency. Does anyone who knew Andrew, or who spent time in the Sedro-Woolley backcountry in late December 1997, have information that could help fill the gaps in this case?
