Rene Rigoberto Rivas Castellanos was 40 when he last spoke with family by phone on May 13, 2006, saying he planned to migrate to the United States through Arizona. He was last known to be in the vicinity of Sasabe in Pima County, a remote crossing on the U.S.-Mexico border, and his family never heard from him again.

Rene is described as a Hispanic male with black hair and a short beard, between 5 feet 10 inches and 6 feet tall, weighing 180 to 200 pounds. It is not known which specific route he intended to take or whether he was traveling with anyone. The Pima County Medical Examiner’s Office is listed as the investigating agency.

His family has had no answers since that final call and continues to hope for information. If anyone knew Rene, saw him near Sasabe around May 2006, or has information about his planned route, please share what you know.
