Pete Mallare, age 81, was last seen in Chula Vista, California, on January 23, 2004. Very few details about his movements that day have been made public, and his disappearance remains unsolved. He was described as an elderly man and potentially vulnerable to age-related cognitive or physical limitations when he went missing.

Authorities have kept the case open but report no significant leads in the years since his disappearance. His case is one of many unresolved missing person files involving seniors in California.
