Summary based on the NamUs case record (MP15936) and 1 other source
In 2007, a young man named David Martinez Lopez, then 25 years old, vanished under vague circumstances. He was last seen in Nogales, Arizona, a city that straddles the U.S.-Mexico border. The exact date of his disappearance remains unknown, adding a layer of uncertainty to the case. What is known is that he was last seen at some point in 2007 while crossing the border from the United States into Mexico. At the time he went missing, he was described as a Hispanic male with brown, curly hair and brown eyes. His height was estimated to be between 5'5' and 6'0', and his weight between 176 and 180 pounds.

Distinctive physical characteristics were noted that could aid in his identification. He had dimples that appeared when he smiled. He also had several scars and marks, including a cut scar on his right hand, a mole with hair on his coccyx, and another mole on his right buttock. The clothing and accessories he was wearing at the time of his disappearance are unknown, and there is no information about his mode of transportation. His case was officially entered into the National Missing and Unidentified Persons System on July 30, 2012, several years after he was last seen. The Pima County Office of the Medical Examiner is the investigating agency.

The circumstances surrounding David Martinez Lopez's disappearance are sparse, leaving his family with few answers. The primary detail is that he was last seen crossing the border near Nogales. The lack of a specific date for his last contact makes the timeline of his disappearance difficult to establish, further complicating the investigation. Over the years, his case has remained open, a quiet but persistent mystery. The overview of the case highlights a young man who disappeared at a border crossing, with few clues to explain what happened to him after he was last seen.

Last Seen: Jan 1, 2007
