John Hansen was 63 when he was last seen on July 12, 1990, near the Napa River north of State Route 37 in California. All of his personal belongings were reportedly left behind, and searches in the area produced no substantial leads.

The location beside the Napa River and the surrounding terrain have complicated search efforts, and authorities have been unable to determine whether foul play, an accident, or another cause was involved. The case remains open and has drawn attention as part of efforts to resolve long-term missing persons cases in California.

Hansen’s family continues to hope for answers and law enforcement is seeking tips from anyone with information about his disappearance. If anyone knew John Hansen or was in that area on July 12, 1990, can you share what you remember?
