Jorge Argueta Diaz was 19 when he was last seen near Falfurrias, Texas, on July 22, 2015. He had been walking with a group across South Texas, reportedly about 24 hours on foot from McAllen, and the group was later picked up by a van. After roughly 30 minutes of travel in that vehicle, Jorge was left by the side of the road for reasons that remain unclear. He has not been seen or heard from since.

Family and investigators say there are no substantial leads explaining what happened after he was abandoned, and the case remains open. Anyone who was in that area on July 22, 2015, or who has information about the van, the group Jorge traveled with, or his movements after he was left by the roadside is asked to come forward.
