Norman Allen Griffiths was 52 when he went missing in May 1996 after setting out on a hike in Snohomish, Washington, to look for stones. An avid outdoorsman, his trip was described as routine, yet he never returned and has not been seen or heard from since.

At the time he disappeared Griffiths was described as a White male, 5 feet 5 inches tall, about 110 pounds, with brown hair, blue eyes, missing teeth and a scar on his chin. He was reportedly wearing blue jeans, a gray plaid shirt and a gray coat the day he vanished. The Everett Police Department investigated, but leads ran dry and the case became a long-term missing person file and later a cold case.

Does anyone who knew Norman, his hiking routes, or the Snohomish area in May 1996 have information that could help his family and investigators?
