Summary based on the NamUs case record (MP112006) and 1 other source
In the spring of 2022, concern began to grow for 25-year-old Nathan Tomas Guerena, a resident of Tucson, Arizona. His mother, with whom he maintained regular phone contact, last spoke with him on April 5, 2022. At the time, Nathan, a Hispanic male standing 5 feet 10 inches tall and weighing around 230 pounds, was living with a roommate. Distinctive features include his brown hair, brown eyes, and gauges in his ears. As days turned into weeks with no word, the silence became increasingly alarming for his family.

The circumstances surrounding Nathan's disappearance are unsettling and have left his loved ones searching for answers. His roommate also had not seen or heard from him since early April of that year. The vehicle Nathan had been using, which belonged to his mother, was found left at his residence. Investigators believe he had his cell phone and wallet with him, as they were not located in his home. The Tucson Police Department was notified, and a report was filed on April 17, 2022, officially marking the start of the investigation into his whereabouts.

The case of Nathan Guerena remains unresolved, a painful reality for his family and the Tucson community. Public records indicate a past encounter with law enforcement in 2019, though it is not stated to be connected to his disappearance three years later. His case is listed in the National Missing and Unidentified Persons System a national resource for missing person cases. The lack of significant leads has made the investigation particularly difficult for authorities. The overview of this case is one of a sudden and unexplained absence, leaving a void filled with unanswered questions for those who know and love him.
