Summary based on the NamUs case record (MP2024) and 3 other sources
Martin Nungaray Ruvalcaba, aged 47, was last seen on February 14, 2009, at his home in Newman, California. He disappeared after walking out of the garage door of his family residence and has not been heard from since. Ruvalcaba, who suffers from Huntington's disease and dementia, was known to wander and had previously been found walking near fields and canals around town. His medical conditions significantly affected his memory, leaving him unable to recall his name or residence, making his disappearance even more concerning.

On the day of his disappearance, Ruvalcaba was wearing a black sweater, blue jeans, and a Medic Alert bracelet, identifying his health issues. Despite previous instances of wandering, he had never been gone for more than a few days. His disappearance has puzzled authorities, and few details have emerged since he was last seen. Efforts to locate him continue, with local police seeking any information that could help bring him home.
