Michael Eric Hansen was 45 when he vanished from Yakima, Washington, last seen on November 4, 2007. He was a Native American man, about 5 feet 7 inches and 140 pounds, with black hair, brown eyes, prescription glasses, scars on both arms and a limp in his right leg. He lived in White Swan and worked at Yakama Forest Products.

Several days after he was last seen, his vehicle was found abandoned near the Yakima River with the keys in the ignition, the parking brake set and the driver’s side door open — details that point to a sudden, unexplained departure. Both the Yakima County Sheriff’s Department and the Yakama Nation Tribal Police investigated but no substantial leads emerged.

Who knew Michael or might have seen him in late October or early November 2007?
