Summary based on the NamUs case record (MP15682) and 1 other source
In the vast and often unforgiving landscape of Arizona, the story of Porfirio Cineceros’s disappearance is a somber reminder of the many who have vanished with little to no explanation. A Hispanic male, between the ages of 35 and 37 at the time he went missing, Porfirio was last seen on June 17, 2001. The last known location for him was Yuma, Arizona, a city nestled in the Sonoran Desert. He stood between 5 feet 8 inches and 5 feet 10 inches tall, with a weight ranging from 190 to 210 pounds. The circumstances provided about his disappearance are sparse, noting he was last seen in an area described as 'West of Charlie Bell Well, to Growler Mtns, near Yuma.' Beyond these basic details, the narrative of what happened to Porfirio fades into the landscape, leaving a void of information for those who may have known him.

The official investigation into the disappearance of Porfirio Cineceros is handled by the Pima County Office of the Medical Examiner, based out of Tucson. This detail adds a layer of complexity to the case, as Yuma, where he was last seen, is in a different county. This could suggest that evidence or circumstances led investigators to believe his case was better handled by the medical examiner's office, a common occurrence when a person is missing and presumed to be deceased. The case, cataloged under the number MP15682, shows a significant gap in time between his disappearance in 2001 and when the case was formally created or reported to this agency, which occurred years later. This delay could be for a variety of reasons, including a lag in reporting or the discovery of new information that prompted the case's creation.

The passage of time has done little to bring clarity to the case of Porfirio Cineceros. With unknown hair and eye color in public records, creating a complete picture of him is challenging. His clothing at the time of his disappearance is also listed as unknown. This lack of descriptive detail further complicates efforts to locate him or uncover what might have happened. The Pima County Office of the Medical Examiner holds jurisdiction over a large number of cases involving unidentified remains, many of whom are found in the harsh desert environment that spans much of the region. The overview of this case is one of profound ambiguity. A man vanished from a specific yet remote area of Arizona over two decades ago, and the trail of information available to the public appears to have gone cold. With no updates on his whereabouts or the circumstances of his disappearance, the case of Porfirio Cineceros remains an open and unresolved question, a silent testament to the enduring mystery that surrounds so many missing persons.
