Phyllis Eleanor Berry was 21 when she vanished from the World Championship Chili Cook-Off in Terlingua, Texas. She was last seen around midnight on November 1, 1975, sitting by a campfire a short distance from contest headquarters after traveling to the event from Odessa with her roommate. The cook-off drew an estimated 10,000 to 15,000 people that weekend.

Witnesses said she may have left on the back of a Honda 350 motorcycle with an unidentified blond man in his twenties. Her roommate said Phyllis left all her belongings behind and was happy with her life, casting doubt on a voluntary disappearance. Local authorities suspect foul play, but no significant leads have developed.

Phyllis Berry’s case remains unsolved and her family continues to seek answers. Anyone with information about her whereabouts or the events that night is asked to contact law enforcement.
