Christopher Gomez Villalobos, 21, was reported missing from McAllen, Texas, on August 11, 2011. He was last known to have crossed the U.S.-Mexico border in the McAllen area. Christopher is described as 5 feet 6 inches tall, about 200 pounds, with brown hair.

Public details are scarce and the disappearance remains unresolved. The last known location near the border means cross-border factors may be relevant and could complicate the search. Local authorities continue to ask anyone with information to come forward.

If anyone knew Christopher, saw him around McAllen in August 2011, or has information about his border crossing, please share what you know with investigators.
