The case was entered into NamUs on July 30, 2012, and the official circumstance is listed as last known to be crossing the U.S.-Mexico Border near Sasabe. Many details about why he attempted the crossing and what happened afterward remain unknown.

If anyone traveling in or near the Sasabe corridor in late March 2008 remembers seeing Carlos or found items that match this description, please share information that could help his family.
