Carlos Claros, 31, a Hispanic male, was fatally shot in the early morning hours of June 8, 2025, after a parking-lot fight outside LUNA Live Music Bar at 6740 San Pedro Avenue on San Antonio’s North Side. Police were called around 5:30 a.m.; one victim was found with multiple gunshot wounds outside the bar and pronounced dead at the scene, while the other—later identified as 45-year-old Guillermo Serrano Jr.—was rushed to a hospital where he died.
The Bexar County Medical Examiner ruled both deaths homicides caused by gunshot wounds.
Witnesses described a disturbance that began with a group of women and escalated as two men became involved, leading to gunfire in the lot. Initial on-scene accounts suggested the two men may have shot each other during the fracas, but a subsequent preliminary police report stated the shooter fled before officers arrived, shifting the investigation away from a mutual exchange toward a single-gunman scenario. The Texas Alcoholic Beverage Commission also opened an inquiry related to the incident at the bar.
By mid-August, detectives publicly named 28-year-old Samuel Adrian Barron as the suspect in the double killing and obtained a warrant for capital murder of multiple persons. Authorities released images of him and said he had ties to Mexico, adding that he was believed to have crossed the border within hours of the shooting. Crime Stoppers bulletins repeated those details and specified that officers found Claros deceased at the scene while Serrano succumbed to his injuries at the hospital. The police appeal urged anyone with information to contact the SAPD Homicide Unit, noting the charge carries penalties up to life imprisonment without parole or the death penalty. As of the latest reports, Barron remained at large.
Claros’s death was formally confirmed days later when the medical examiner released his identity and cause of death, closing the grim loop that began with a brawl in a dim parking lot and ended with two families in mourning. Local outlets chronicled the aftermath as investigators pieced together the timeline from the burst of violence to the suspect’s flight, while community tip lines and state regulators continued their parallel efforts to account for what happened and who should be held responsible.
