Robert M. Kruip, 23, was last seen leaving his family’s home in Fullerton, California, on July 30, 1980. His family later found his car at a train station and believes he may have traveled toward the San Diego area. A letter postmarked Solano Beach on July 31 arrived sometime after his disappearance; Kruip wrote that he was fine but needed some time away and suggested he might be traveling to Mexico.

Kruip’s family reported him missing in March 1981, about eight months after he was last seen. There has been no further contact or confirmed trace of him since the letter. Few details are available about his movements after July 31, 1980.

Did anyone in the Fullerton, Solano Beach, or San Diego areas remember seeing Robert Kruip or his car around that time?
