Plaza El Rey sat just miles north of the United States, Mexico border, a rustic venue built for jaripeos, rodeos, and regional Mexican concerts. That Sunday night, an estimated 2,000 patrons crowded the grounds to watch Joan Sebastian perform on horseback. Trigo, the singer's son with his first wife Teresa González, managed backstage logistics, equipment coordination, and artist movement alongside a small entourage of private security personnel.
Trouble started as the performance ended around 11:30 p.m. Fans swarmed the area near the tour bus demanding autographs and photographs with the singer. Private security barriers buckled. Several men attempted to push past the rope line into the private dressing area, prompting Trigo and his crew to push them back.
Witness accounts collected by the Hidalgo County Sheriff's Office described an argument that escalated within seconds. Rather than dispersing, three individuals retreated to an adjacent parking lot, retrieved firearms, and returned to breach the rear perimeter.
