Volker Puschkeit, 26, went missing after being seen on October 30, 1994, in Lee Vining, California, while on a vacation in the United States with companion Herbert Frank, 52. The two had reportedly won about $10,000 at a Reno casino and were last seen at a Lee Vining hotel; witnesses recalled them talking about their winnings.

Their rental car was later found abandoned near Lucky Boy Pass in a remote area of Mineral County, Nevada. Passports, suitcases and other personal belongings remained in the vehicle, but neither man was found. Authorities described the circumstances as suspicious and treated the case as possibly involving foul play. Extensive air and ground searches turned up no leads.

Who knew Volker or Herbert, traveled with them in late October 1994, or saw their car near Lucky Boy Pass?
