Summary based on the NamUs case record (MP76422) and 4 other sources
In the winter of 2013, a family was grappling with a recent loss and a new beginning. Fourteen-year-old Manuel Michael Anthony Ruiz, a young man of Hispanic and American Indian descent, had recently moved to Phoenix, Arizona, with his mother and brother from Winslow, Arizona. The move followed the untimely death of his father, a difficult transition for any teenager. On December 21, 2013, Manuel, who stood 5 feet 6 inches tall with black hair and brown eyes, was last seen in the area of North 16th Avenue and West Glendale Road in Phoenix. At the time of his disappearance, he weighed around 120 pounds and was identifiable by a two-inch scar on the back of his right hand. That day marked the beginning of an enduring mystery, as the young boy vanished without a trace.

The days following Manuel's disappearance turned into weeks, then months, and now years of unanswered questions for his loved ones. While Manuel had a history of running away, this time was different; he had always made contact or returned home in the past. His complete silence was uncharacteristic and alarming. Authorities were notified, and an investigation was launched by the Phoenix Police Department, classifying his case as one of an endangered missing person. There was some speculation that he might have attempted to travel back to Winslow, a place with which he was familiar, or that he may have remained somewhere in the vast Phoenix metropolitan area. However, these theories have never been substantiated with any concrete evidence, leaving investigators with very few leads to follow.

The passage of time has not diminished the hope of finding answers. Manuel's family, particularly his mother, has remained steadfast in the search. The case of Manuel Michael Anthony Ruiz is a haunting story of a child who disappeared amidst a period of family turmoil and transition. He was a 14-year-old boy, known to sometimes use aliases such as Daniel Rodriguez, Manuel Avendano, or Anthony Avendano, who was last seen in a specific area of Phoenix on a December day and was never heard from again. The lack of significant leads or confirmed sightings has made this a particularly challenging case for law enforcement, leaving his family and community with a profound sense of uncertainty and a search for closure that continues more than a decade later.
