Rosario Guadalupe Arias-Mariscal was last seen in Phoenix on July 20, 2014, at age 21. He is described as a Hispanic male, 5 feet 4 inches to 5 feet 6 inches tall, 145 to 155 pounds, with black hair, brown eyes and a scar near his navel. When last seen he was wearing a maroon short-sleeved t-shirt, gray jeans and maroon tennis shoes, possibly Polo brand. Investigators note he may use the alias Victor Manuel Arevalos.

A report to the Phoenix Police Department was not filed until September 21, 2016, more than two years after his disappearance. Very few other public details about his movements that day have been released, and the case remains open with the Phoenix Police Department seeking information.

If anyone knew Rosario, saw him in Phoenix around July 20, 2014, or has information about the name Victor Manuel Arevalos, please contact the Phoenix Police Department.
