Nicanor Rueda Castro, 28, disappeared in the summer of 2011 after being last seen on August 16, 2011, in Arizona. He was reported to the Pima County Medical Examiner’s Office on August 18, 2011. At the time he was described as a Hispanic male, 5 feet 3 inches to 5 feet 4 inches tall, 160–170 pounds, with brown hair and brown eyes, and a large brown mole about 10 centimeters on his back. He was last reported wearing a white cotton T-shirt and blue jeans.

Reports say he was last seen crossing the U.S.–Mexico border into Arizona; what happened to him after that crossing remains unknown. He has used the aliases Antonio Plancarte and Nicolas Rueda. The Pima County Medical Examiner’s Office is the primary agency listed on the case, which remains open with few concrete leads.

If anyone has information about Nicanor’s movements in August 2011 or recalls seeing him after August 16, please share what you know.
