Christoph Zahn was a 20-year-old Swiss citizen traveling the United States when he vanished in spring 1992 after arriving in Atlanta. He checked into a hotel across from the bus station after an overnight ride from Jacksonville and was last heard from in the late afternoon via a phone call placed from a Denny’s in Tucker to his travel agent in Orange County, Florida. He is described as about 6 feet 3 inches to 6 feet 4 inches, 155–160 pounds, light brown hair, brown eyes, with a chin scar; he was wearing a turquoise cap and blue jeans and spoke English with a slight German accent.

Investigators later linked repeated use of his credit card in the Atlanta area to Harry Eugene Hale; Hale was arrested and convicted for the fraudulent use of the cards and police recovered several of Christoph’s belongings at Hale’s Kentucky home, but Hale was not charged in Christoph’s disappearance. Authorities suspect foul play but the case remains unresolved.

Did anyone in the Atlanta area know Christoph or recall seeing him around the bus station or Tucker the week he disappeared?
