Jeronimo Rubio-Hernandez, 40, was reported missing after a July 25, 2013 group crossing near Falfurrias, Texas. He was one of about 19 people walking through harsh terrain. After three days on the trail, Jeronimo reportedly collapsed and was left behind by the group near a highway, said to be close to an abandoned windmill, before the group reached a checkpoint on July 27, 2013.

His disappearance is listed in NamUs and no further public information about his whereabouts has been posted. Authorities continue to seek tips and any information that could resolve what happened. The circumstances remain unclear and underscore the hazards faced by people making that route.

If anyone saw Jeronimo, the group he was with, or activity near the abandoned windmill area in late July 2013, please share what is known with investigators.
