Summary based on the NamUs case record (MP18371) and 1 other source
On December 29, 1997, 27-year-old Andrew Jonathon Zalcberg was last seen in Sedro-Woolley, a town in Skagit County, Washington. He was a white male with blond or strawberry-blond hair and blue eyes, standing at 5 feet 9 inches tall and weighing around 145 pounds. At the time he went missing, it was believed that he had departed from a remote location on foot. There was a possibility that he was intending to travel to Colorado, though there is no evidence to suggest he ever arrived there. For years, the circumstances of his disappearance remained a mystery, with no significant leads to indicate what might have happened to him.

A significant development in the case came in 2008 when a femur bone was found in a creek bed. The location of this discovery was in the general vicinity of where Andrew was last seen. Through DNA testing, the bone was confirmed to be his. This discovery, while providing a crucial piece of information, also brought a somber turn to the investigation. The hope of finding Andrew alive was tragically diminished, yet the discovery of only a single bone left many questions unanswered. No further remains were located, which has made it difficult for investigators to determine the exact circumstances that led to his death.

The Skagit County Sheriff's Office has been the investigating agency for this case, which was officially reported on the same day Andrew was last seen. Despite the passage of time and the partial discovery, the case remains shrouded in uncertainty. The lack of further remains or any other evidence has left family and investigators without a clear understanding of the events that transpired after he left on foot that December day. The official circumstances of his disappearance simply state that he left a remote location with a possible destination of Colorado, a journey he seemingly never completed. The case is an ongoing and unresolved investigation into what happened to Andrew Zalcberg.

Last Seen: Dec 29, 1997
