Summary based on the NamUs case record (MP7725) and 4 other sources
Mark Johnson, a 26-year-old man, was last seen on March 1, 1997, in San Diego, California. He left home around 2:00 a.m., and after that, he was never seen again. His girlfriend reported him missing, as he failed to return or make any contact. Mark was known to frequently visit Tijuana, Mexico, and there was speculation that he may have traveled there before his disappearance. However, no confirmed sightings or leads have emerged since that time.

Mark was described as a white male, approximately 5'10" tall, weighing 155 pounds, with brown hair. Despite efforts to locate him, his case remains unsolved. Authorities continue to investigate his disappearance and urge anyone with information to come forward.

His case is still listed in databases like NamUs, and his family continues to seek closure and answers regarding his fate.
