Allen Clair Bigham, aged 50, was last seen in San Diego, California, on March 25, 2002. He had a history of drug and alcohol abuse but was reportedly sober at the time of his disappearance. On the night he went missing, Bigham called a cab around midnight and has not been heard from since. He was last seen by his father, and after that, no trace of him has surfaced.

Bigham is described as a White male, standing between 5'8" and 5'11" tall, weighing around 165 to 175 pounds, with gray hair and blue eyes. He was partially balding and had a gray mustache at the time. On the day he disappeared, he was wearing blue jeans, a tan jacket, and brown tennis shoes. Despite the efforts of authorities, including the San Diego Police Department, Bigham's whereabouts remain unknown.

His case is still unsolved, and anyone with information is encouraged to contact law enforcement. Both DNA and fingerprints are available in case further identification efforts are needed.
