Las Cruces shooting suspect’s dark past: NM Dems killed bills to stop these crimes
The only adult thus far charged in connection with Friday night’s mass shooting at Las Cruces’ Young Park had previously faced serious criminal charges in Texas — including smuggling offenses that prosecutors say point to his danger to the public.
Court documents from El Paso County show that 20-year-old Tomas Rivas was charged in January 2024 with four counts of smuggling persons and one count of evading arrest. His criminal history dates back to 2021 when he was 17 and arrested for transporting an illegal immigrant.
These past and pending charges are now part of the evidence presented by the 3rd Judicial District Attorney’s Office in a motion to keep Rivas in jail pending trial. Prosecutors argue that no conditions of release would ensure public safety.
“[He] has a history of criminal activity which appears to be gang-related,” the District Attorney’s Office noted in its pretrial detention motion. Rivas, they added, has been residing in Las Cruces for some time and is employed at a local Sonic Drive-In.
Rivas is among four individuals — including three teenagers — charged in the deadly shooting that killed three young people and wounded 15 others. According to police, multiple people opened fire into a crowd during an unsanctioned car show at Young Park. The victims were identified as Dominick Estrada, 19; Andrew “AJ” Madrid, 16; and Jason Gomez, 17.
Rivas and the three teens — two 17-year-olds and a 15-year-old — each face three counts of first-degree murder. Police said Rivas and one of the teens attempted to dispose of four handguns in a dumpster. Those firearms, all semi-automatic pistols, were later recovered.
Authorities also reported that one teen sought refuge in a nearby apartment, where a resident later found another gun that belonged to him. All three juveniles were booked into the juvenile unit of the Doña Ana County jail, while Rivas was held in the adult section after being arrested on Las Cruces’ north side.
Third Judicial District Attorney Fernando Macias told the Albuquerque Journal that he plans to prosecute all four as adults. “The first thing that we’re going to address, hopefully very quickly, is keeping them in custody,” Macias said. He added that under New Mexico law, suspects over age 15 can be charged as adults.
The shooting, which shook the Las Cruces community, follows years of concerns about youth involvement in criminal smuggling operations along the El Paso-Sunland Park corridor. Law enforcement and school officials have long observed how teenagers in the Borderland are recruited into these networks, sometimes with deadly outcomes. Federal agencies like the U.S. Border Patrol have been working for over a decade with local schools in attempts to curb recruitment.
Court filings suggest Rivas may have been involved in such a smuggling network.
As of Monday, prosecutors had filed a motion for pretrial detention. Rivas’ attorney, Thomas Clark, told the Journal he expected a hearing to be scheduled later in the week. Attorneys have also been appointed to represent the juveniles.
Meanwhile, despite repeated concerns from law enforcement, prosecutors, Republicans, and even Democrat Gov. Michelle Lujan Grisham about rising juvenile violence, Democrat lawmakers in the New Mexico House and Senate declined to advance legislation during the recently concluded 60-day legislative session that would have strengthened penalties or accountability measures for violent juvenile offenders.
