Summary based on the NamUs case record (MP24142) and 3 other sources
Rosendo Alba Mena, a 26-year-old man, was last seen on August 11, 1996, in Fontana, California. Very little is known about the circumstances surrounding his disappearance. He vanished without leaving many clues, and no significant developments have emerged in the years since. At the time of his disappearance, Mena was described as a Hispanic male with brown hair and brown eyes, standing 5 feet 6 inches tall and weighing about 140 pounds.

There is no available information regarding what he was wearing at the time he went missing, nor are there any clear details about his activities before his disappearance. Despite investigations by the Fontana Police Department, the case remains unsolved, and Mena has not been heard from or seen since that day. His case has been classified as a missing person case with no clear indications of foul play or other leads.

Efforts to solve this case continue, though the lack of evidence makes progress difficult. As of today, his family and law enforcement are still searching for any information that could lead to answers about his fate.
