Carlos Costilla Espinoza, 24, was last seen May 8, 2016, after crossing from Piedras Negras, Mexico, into Eagle Pass, Texas, with his brother. The men had been walking for nearly 18 hours without rest or food. Around 10 p.m. that evening Carlos became highly agitated and frightened and ran off into the darkness; his brother has not seen or heard from him since.

Search efforts and an ongoing investigation have not produced new information. Does anyone who was in the Eagle Pass area that night or who knew Carlos have information to share?
