Summary based on the NamUs case record (MP17987) and 2 other sources
In the vast and often unforgiving landscape of the Sonoran Desert, the story of Aurelio Contreras Quintero's disappearance began on July 15, 2012. At the age of 34, Aurelio, a Hispanic male, was on a journey that would lead him to the U.S.-Mexico border near the small community of Lukeville, Arizona, in Pima County. It was in this remote and challenging environment that he was last seen, a place where countless stories of hope and hardship intersect. He stood between 62 and 64 inches tall, with brown hair and brown eyes. The day he vanished, he was reportedly wearing Levi's brand blue jeans, a black shirt, and a baseball hat adorned with a 'W.' Among his few possessions was a Mexican voter ID card, a small token of his identity left to tell a part of his story.

The circumstances surrounding Aurelio's disappearance are sparse, with the primary detail being his attempt to cross the border. This single piece of information opens a door to a world of possibilities and dangers inherent in such a journey. The desert itself is a formidable adversary, with its extreme temperatures, rugged terrain, and vast, unpopulated expanses. For those who travel through it, the risk of becoming lost or succumbing to the elements is a constant and serious threat. The Pima County Medical Examiner's Office took on his case, a testament to the unfortunate frequency of such disappearances in the region. The area is known for the high number of unidentified human remains recovered, a somber reality of the perils faced by many who undertake similar crossings.

The search for Aurelio Contreras Quintero has been a quiet one, largely absent from major headlines, yet his case represents a narrative familiar to many families who have lost loved ones in the borderlands. The lack of detailed public information speaks to the challenges investigators face in cases like his, where the trail can go cold almost as soon as it begins. The overview of this case is one of uncertainty and unanswered questions. A man, described by the few details available, embarked on a journey and was never heard from again. His case remains a poignant reminder of the human element behind the complex issues of border crossings and the silent tragedies that unfold in the harsh beauty of the Arizona desert.
