Summary based on the NamUs case record (MP13152) and 2 other sources
In the winter of 2010, a man named Genaro Martinez Martinez, then 40 years old, embarked on a journey that would leave his family with years of unanswered questions. On December 25, 2010, he was last in contact with his loved ones before setting out from Mexico with the intention of crossing the border into Arizona. His destination was the area of Tucson, but his family never heard from him again after he began his trek in January of 2011. Genaro was a Hispanic male, standing between 5'8' and 5'9' tall and weighing between 145 and 175 pounds. He had short black hair, brown eyes, and a distinct physical characteristic of two extra nipples just below his chest.

The exact details of what transpired after Genaro crossed into the United States remain unknown. The terrain in southern Arizona is notoriously harsh and unforgiving, particularly for those traveling on foot. The vast and rugged Sonoran Desert presents extreme heat, challenging landscapes, and other life-threatening conditions for the many migrants who attempt to cross through its dangerous backcountry routes. It is a somber reality that human remains are frequently discovered in this region, often leaving authorities with the difficult task of identification. The Pima County Medical Examiner's Office, which is the investigating agency for Genaro's case, handles a significant number of such cases each year.

The passage of time has not brought any definitive answers for Genaro's family. His case was formally created in the National Missing and Unidentified Persons System on December 3, 2011. The circumstances of his disappearance are a poignant reminder of the perils faced by many who undertake similar journeys. The Pima County area, in particular, faces a significant challenge with hundreds of sets of unidentified human remains, a situation that has been described as a 'chronic mass disaster' by anthropology experts. Genaro's case remains an open investigation, a story without a final chapter, representing one of the many individuals who have vanished while seeking a new life across the border.
