Summary based on the NamUs case record (MP16361) and 1 other source
On November 25, 2009, a 31-year-old man named Manuel Fernando Estrada Diaz was last seen in the border region of Nogales, Arizona. At the time of his disappearance, he was reportedly wearing a t-shirt, blue jeans, a black belt, and white tennis shoes. The circumstances surrounding his last known moments are vague, with reports only indicating he was seen crossing the border, though whether it was near Nogales or Douglas, Arizona, remains uncertain. Since that day, there has been no contact from him, and his whereabouts have remained unknown, leaving a painful void for those who knew him.

Manuel is described as a Hispanic male, standing between 5 feet 4 inches and 5 feet 6 inches tall, and weighing between 158 and 178 pounds. He has brown hair and brown eyes. A notable distinguishing physical feature is a large mole on the upper right side of his mouth. These details, while specific, have not yet led to a breakthrough in his case, and the passage of time has only deepened the mystery surrounding his disappearance. The lack of detailed public information about his life and the reasons for his border crossing adds to the complexity of the situation, leaving many questions unanswered.

The Pima County Office of the Medical Examiner is the investigating agency for Manuel's case, which is documented under the agency case number FSC MPR 1569. Despite the official record of his disappearance, there is a notable absence of public information regarding the investigation or any leads that may have been pursued over the years. This lack of available information contributes to the difficulty in understanding the full scope of what happened to Manuel Estrada Diaz. His case is a somber reminder of the many individuals who vanish, leaving behind fragmented stories and an enduring search for answers. The overview of this case is one of an abrupt and sorrowful disappearance with very few details available to the public.
