Summary based on the NamUs case record (MP83778)
Denis Hernandez Guerra, a 36-year-old male, was last seen on July 30, 2021, in McAllen, Texas. Originally from Nicaragua, Denis had been attempting to cross into the United States illegally. Since his disappearance, there have been no confirmed sightings, and efforts to locate him, including attempts to find any record of him in ICE custody, have been unsuccessful.

Given his last known location near the U.S.-Mexico border, it is believed that Denis may have been attempting a perilous journey, which often involves dangerous conditions. Authorities and his loved ones continue to seek information about his whereabouts, but thus far, his case remains unsolved.

Investigations are ongoing, and anyone with information is urged to come forward to assist with the case. The lack of new leads has made it challenging to determine what happened to Denis following his last sighting.
