Summary based on the NamUs case record (MP50531) and 3 other sources
Harold Smith, a 44-year-old man, went missing on January 18, 1980, from the Frank's Tract area in California. Despite extensive search efforts, no trace of Harold has been found. He was last seen in this marshy region, which is challenging terrain for searches. At the time of his disappearance, not much specific information regarding his movements or potential whereabouts was recorded, and details have remained scarce throughout the years.

Harold's case remains unsolved, and he is listed in national missing person databases. Given the nature of his disappearance, authorities have continued to encourage the public to provide any potential information that could help solve this long-standing case.

Last Seen: Jan 18, 1980
