Ronald Bell Rivera was 24 when he was last seen in Brownsville, Texas, on April 28, 2006.

His disappearance is still listed in missing person databases, including NamUs, and the investigation is open. Because of the length of time since April 2006, the case is considered cold, but authorities say any new information could be important to locating him and providing answers for his family.

If anyone remembers Ronald, his last known movements, associates, or has other information that might help, please share what is known with the appropriate law enforcement agency.
