SAN ANTONIO – A co-defendant in the February 2023 shooting death of Duniel Valladares Fernandez has been sentenced to 30 years in prison, closing out the prosecution of both men accused in the case, according to the Bexar County Criminal District Attorney’s Office.

Adis Hernandez-Rivas was sentenced Thursday, July 23, 2026, in the 187th District Court, which is presided over by Judge Stephanie Boyd. Prosecutors said Hernandez-Rivas pleaded guilty in a plea agreement and “accepted responsibility for his role in the offense.”

The district attorney’s office said law enforcement responded to a shooting in February 2023 and found Fernandez suffering from a gunshot wound to his upper body. Officers and first responders rendered aid, but Fernandez died at the scene, the release said.

Investigators determined Hernandez-Rivas and co-defendant Marco Antonio Moreno Vasquez confronted Fernandez over a financial dispute, according to the district attorney’s office. Evidence showed Moreno Vasquez provided Hernandez-Rivas with a firearm and instructed him to shoot during the confrontation, the release said.

Surveillance video captured the shooting and provided images of the suspects and the suspect vehicle’s license plate, according to the district attorney’s office. Days later, Atascosa County law enforcement located the vehicle during a traffic stop, and Hernandez-Rivas and Moreno Vasquez were identified and taken into custody, the release said.

Investigators later recovered the murder weapon from Moreno Vasquez’s residence, where it was concealed inside a refrigerator among food items, according to the district attorney’s office. Ballistics testing confirmed the firearm matched shell casings recovered from the homicide scene, the release said.

Moreno Vasquez was previously convicted and sentenced to 40 years in prison for his role in the murder, according to the district attorney’s office.

Assistant Criminal District Attorneys Meghan Galloway and Lauren Espinoza led the prosecution, with support from Victim Advocate Rose Perez and Investigator Rudy Rangel, the release said.

“This case demonstrates that everyone who plays a role in a violent crime will be held accountable,” Bexar County District Attorney Joe Gonzales said. “Today’s sentence brings another measure of justice for Duniel Valladares Fernandez and his loved ones. I want to thank our prosecutors, investigators, victim advocate, and our law enforcement partners for their dedication and commitment to seeing this case through to its conclusion.”
