Helmut Ernst Altmann, a 31-year-old Austrian national, vanished while on a business trip to Beverly Hills. He checked into the Regent Beverly Wilshire Hotel on October 26, 1984, with a checkout set for October 31 and a return to Austria booked for November 2. He was last seen in his hotel room on October 30.

Altmann was believed to have gone sightseeing in the Big Sur area that day, driving a rented white 1984 Chevrolet Camaro that has never been found. When his wife reported him missing on November 6, hotel staff found his room undisturbed and noted his passport, money, clothing, and return airline ticket remained behind. Authorities regard the disappearance as suspicious and the Beverly Hills Police Department continues to investigate.
