Summary based on the NamUs case record (MP15654) and 1 other source
Dionisio Perez-Hernandez, a 25-year-old male, was last seen on August 5, 1996, near the U.S.-Mexico border close to San Diego, California. He was reported missing while attempting to cross the border, and his whereabouts have remained unknown ever since. Described as a Hispanic male with black hair, Dionisio was approximately 5'6" tall and weighed 160 pounds at the time of his disappearance.

There is very limited information available regarding the circumstances of his disappearance, but he has not been located, and no new developments have emerged since he went missing. The case remains open, and authorities continue to seek any information that could lead to finding Dionisio.

Investigators encourage anyone with knowledge of his case to come forward to help shed light on what might have happened to him on that day in 1996. His disappearance is still being handled as a missing person case by the relevant law enforcement agencies.
