Marcus David Antley, 66, a male and longtime Eagle Pass resident, was fatally shot shortly after midnight on September 28, 2025, outside the Kickapoo Lucky Eagle Casino. A retired U.S. Customs and Border Protection agent known locally as “Mark,” he had gone to the casino on a busy raffle night when gunfire erupted, striking him and several others amid the crowd. One victim died at the scene and another en route to the hospital; officials later identified the second person killed as Alicia
“Daniela” Sanchez, while five additional people were injured. Community leaders—including Eagle Pass Mayor Aaron Valdez—publicly mourned Marcus David Antley, 66, recalling his years of public service and the friendships he built across the border community. The casino temporarily closed as tribal police and partner agencies secured the area and began their investigation.
As law enforcement pieced together the timeline, attention turned to a black Nissan pickup seen leaving the property. Using vehicle tracking information, authorities pursued the suspected gunman northeast toward Wilson County. After a brief chase, troopers and deputies arrested 34-year-old Keryan Rashad Jones of San Antonio. Investigators recovered a firearm, and prosecutors announced two counts of capital murder along with multiple aggravated-assault charges tied to the wounded bystanders. Subsequent court filings increased Jones's total bond as additional charges were added, and the case—complicated at first by overlapping tribal, state, and federal jurisdictions—remained under active investigation by the Kickapoo Traditional Tribe of Texas Police Department with support from the Texas Rangers, DPS, and the FBI.
In the days that followed, friends and neighbors painted a portrait of Marcus David Antley, 66, male, as a steady presence who spent decades in federal service and never stopped looking out for others. His wife, injured during the chaos, described the frantic moments as patrons ducked for cover and called for help amid shattered glass and sirens. Memorial posts and local remembrances echoed the same theme: that the loss of Marcus David Antley, 66, male, had carved a deep absence in Eagle Pass, even as the casino prepared new security measures and the community waited for answers about motive.
Authorities formally recorded the death of Marcus David Antley, 66, male, in Eagle Pass on September 28, 2025, as part of a mass-shooting incident that also left several wounded. Those records, along with local reporting, establish the central facts: the time and place, the identity of the victims, and that a single suspect was arrested and charged soon after. As the legal process moves forward, officials have emphasized support for the families and a commitment to justice in the case stemming from the deadly night outside the Kickapoo Lucky Eagle Casino.
