Summary based on the NamUs case record (MP74762) and 1 other source
On September 6, 2018, a 26-year-old man named Juan De Dios Sandoval Marin went missing. He was last known to be in the southern Arizona desert, a vast and challenging environment. At the time he disappeared, Juan was a Hispanic/Latino male, standing six feet tall and weighing around 130 pounds. He had black hair and black eyes. The specific circumstances leading to his disappearance are not publicly known, creating a painful void for those who care for him. The official report with the Phoenix Police Department was filed much later, leaving a significant gap in the immediate timeline of the investigation into his whereabouts.

Juan has several distinguishing physical features that his loved ones hope might help in locating him. He has a piercing on his lower lip and bears a scar on his thigh from a previous gunshot wound. A particularly personal and identifiable mark is a tattoo on his left forearm, which depicts flowers along with the name 'Olga Marin.' Unfortunately, there is no available information regarding the clothing he was wearing or any personal items he may have had with him at the time he was last seen. This lack of detail adds to the difficulty faced by those trying to piece together his last known movements and understand what may have transpired.

The Phoenix Police Department is the investigating agency in Juan's case. The vague last known location of the 'southern Arizona desert' presents a significant challenge for search efforts and the overall investigation. With limited information about his plans or why he was in that specific area, investigators are left with a difficult and complex case. The absence of concrete leads has left Juan's case open and unresolved, a heartrending situation for his family and friends who continue to await any news. The overview of the case is one of profound uncertainty, centered on a young man who vanished into a remote landscape, leaving behind unanswered questions and an ongoing search for truth.
