Demetrio Sanchez Lopez, 47, was last seen November 23, 2015, while attempting to cross the Rio Grande from Mexico into Texas near McAllen. He was reported missing after that attempt and has not been heard from since. At the time he was described as 5 feet 0 inches tall, 148 pounds, with black hair.

The disappearance took place during an illegal border crossing, a hazardous route because of the Rio Grande’s treacherous conditions. Authorities have checked databases and pursued other lines of inquiry but so far have not located him and the case remains unresolved.

If anyone was in the McAllen area or traveling that stretch of the river on or around November 23, 2015, or has information about Demetrio’s whereabouts, please come forward.
