Summary based on the NamUs case record (MP35371) and 3 other sources
In the summer of 2014, a young man's presence seemingly vanished from the bustling city of Phoenix, Arizona. On July 20th, 21-year-old Rosario Guadalupe Arias-Mariscal was last seen, and since that day, no one has reported hearing from or seeing him. At the time of his disappearance, he was described as a Hispanic male, standing between 5'4' and 5'6' tall, and weighing between 145 and 155 pounds. He has black hair and brown eyes. When he was last seen, he was wearing a maroon short-sleeved t-shirt, gray jeans, and maroon tennis shoes, possibly of the Polo brand. A scar near his navel is a notable distinguishing physical feature.

The circumstances surrounding Rosario's disappearance remain shrouded in mystery, with very few details available to the public. The official report of his disappearance was not filed with the Phoenix Police Department until September 21, 2016, over two years after he was last seen. This significant delay in reporting has undoubtedly complicated the investigation from the outset. Investigators have noted that he may use the alias Victor Manuel Arevalos. The lack of information has left his family and community with a painful void and a multitude of unanswered questions.

The Phoenix Police Department is the investigating agency for this case, and they continue to seek any information that might lead to a breakthrough. The case is a poignant reminder of the many individuals who go missing each year, leaving behind families grappling with uncertainty and hope. The investigation into what happened to Rosario Arias-Mariscal is an ongoing effort to piece together the fragments of a life interrupted and to provide the answers that his loved ones so desperately need. This case represents one of the many unsolved missing persons cases in Phoenix, a city with a significant number of such unresolved investigations.
