Mario Alacran Castillo, 53, was fatally shot on May 3, 2023, in Falfurrias, Texas. The shooting happened about 6 p.m. on South Terrell Street after an argument between two groups escalated into a shootout. Eyewitness Mary Ann Williams said several men were brandishing firearms and the dispute reportedly stemmed from an argument over a woman. Castillo tried to take cover between vehicles but was struck multiple times, including a fatal shot to the back of his head.

Falfurrias police launched a manhunt for the suspects and warned of possible retaliatory violence. Chief William Barton said investigators have some video evidence but that progress has been hindered by residents unwilling to share footage or other information. As of December 27, 2024, no arrests have been publicly reported and the case remains open.

If anyone has information or video that could help identify the shooters, please contact the authorities handling the investigation.
