Summary based on the NamUs case record (MP14553) and 3 other sources
Juan Puente Guzman, a 36-year-old man, was last seen on January 1, 1974, in San Francisco, California. He had been working various jobs in the city, including as a gardener and maintenance worker at apartment complexes. Guzman took a Greyhound bus to visit family in Fresno shortly before his disappearance. After spending about a week with them, his family dropped him off at the bus station for his return trip to San Francisco.

Before leaving, Guzman mentioned to his relatives that he had gotten into trouble over an affair with an apartment owner's wife, and he would contact them once he found a new place to stay. However, after this, he was never seen or heard from again. His disappearance remains unsolved, and no further details or clues have emerged. Fresno police are handling the investigation, but the circumstances surrounding his case remain unclear.
