Genaro Martinez Martinez was 40 when he left Mexico in late 2010 intending to cross into Arizona. He last spoke with family on December 25, 2010, and began his trek in January 2011 toward the Tucson area but was never heard from again. His case was entered into NamUs on December 3, 2011 and remains open.

Genaro is described as a Hispanic male, 5 feet 8 inches to 5 feet 9 inches, 145 to 175 pounds, with short black hair, brown eyes, and two extra nipples below his chest. The terrain he attempted to cross is the Sonoran Desert, noted for extreme heat and dangerous conditions; Pima County routinely handles numerous unidentified remains from that region.

No definitive information about what happened after he crossed into the United States is available. If anyone knew Genaro, saw him in Tucson or southern Arizona in January 2011, or has information that could help identify remains, please come forward.
