A deadly mass shooting at an unsanctioned car show in Young Park, Las Cruces, New Mexico, has left three people dead and 15 others injured. The tragic incident occurred on Friday night when gunfire erupted amid an estimated 200 attendees.

The Las Cruces Police Department (LCPD) identified the deceased victims as 16-year-old Andrew Madrid, 18-year-old Jason Gomez, and 19-year-old Dominick Estrada.

Madrid and Gomez died at the scene, while Estrada was transported to MountainView Regional Medical Center, where he was later pronounced dead.

The ages of those injured range from 16 to 36. Nine men and six women were caught in the crossfire, suffering gunshot wounds. Seven of the victims were taken to hospitals in El Paso, while others received treatment in Las Cruces.

"Officers arrived and learned of multiple gunshot victims. Most were transported to local hospitals. Some were taken to University Medical Center of El Paso," police stated.

Four Suspects Arrested in Connection with the Shooting

Authorities announced on Sunday that four suspects have been arrested, including three juveniles whose names have not been released. The adult suspect, identified as 20-year-old Tomas Rivas, is in custody along with the three minors. All four have been charged with three open counts of murder, with additional charges pending.

Investigators believe the shooting was triggered by an altercation between two groups of people at the car show, which quickly escalated into gunfire.

Eyewitness Recounts the Chaos

Shaquane Heckstall, a 27-year-old Army veteran and team captain of an El Paso-based car club, was present at the event when the violence erupted.

“I heard the pops going off, and I’m thinking it's someone's car, like their exhaust backfiring," Heckstall told ABC News. "But then once it didn’t stop and then people started running, I was like: That’s not what that’s supposed to be."

Heckstall’s military training immediately kicked in as he rushed to assist the wounded. Using makeshift tourniquets—including shoelaces, T-shirts, and sweatpants—he attempted to stop victims’ bleeding.

"Once the gunfire stopped I’m looking around, I see the bodies on the ground," Heckstall said.

He described assisting a teenage victim who pleaded with him to help his father.

“At this point, I'm just trying to make sure he stays awake and keep him talking to make sure that he's still good, you know?" Heckstall said. "I take one of the T-shirts to try and bandage some of the wounds, and then he stops me. He's like, bro, go help my dad."

Mass Shooting Investigation

The Las Cruces Police Department is receiving investigative support from the FBI, the New Mexico State Police, the Dona Ana County Sheriff's Office, and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).

Authorities continue to gather evidence and interview witnesses as the community grapples with the devastating loss of life and the widespread injuries caused by the mass shooting.
