Mauricio Perez Perla, 34, was last seen August 1, 2013, in McAllen, Texas, while attempting to cross the border with a group. Reports say the guide left him behind after he became disoriented and began vomiting; the woman in the group who spoke about the incident said he was left with minimal supplies — an apple, Pedialyte, and a radio — about two hours from a ranch and was alive when they departed. She has refused to provide further details.

There have been conflicting rumors about Mauricio’s fate, including an unverified claim that he was imprisoned, but no solid evidence supports those reports. His family continues to seek answers and the Texas Department of Public Safety has listed him in its Missing Persons Bulletin.

If anyone was in the area that night, traveled with that group, or has information about Mauricio’s movements after August 1, 2013, please share what is known.
