A San Antonio man has been ordered to spend the rest of his life in prison for a chaotic after-hours bar shooting that left three people dead and two others wounded on the city’s East Side in 2021.
Daniel Barragan was sentenced to life for the murders of Dan Edward Martinez Jr. and siblings April and Mauro Rodriguez, according to the Bexar County District Attorney’s Office. Barragan was convicted in the August 2021 shooting outside the after-hours spot, as reported by News 4 San Antonio.
Prosecutors said the violence started inside an illegally operated after-hours room known locally as the "Boom Boom Room" and then spilled into the parking lot when a fight between two women erupted and escalated. Video surveillance and cell-phone clips posted to social media showed Barragan grabbing an assault-style rifle from his vehicle and firing into a crowd, killing three people and injuring two others, according to KSAT.
Another man charged in connection with the shooting, Eduardo Delarosa, later took a plea deal and received a 15-year prison sentence for aggravated assault with a deadly weapon, prosecutors said. Barragan fled the scene but was picked up days later during a traffic stop, officials said. His conviction and life sentence were announced in March 2026, according to News 4 San Antonio.
How prosecutors built the case
Detectives leaned heavily on surveillance video and cell-phone clips posted online to piece together who was involved and where they were during the brawl-turned-shooting. Prosecutors then walked jurors through those images in court, matching faces and clothing to people on the scene. Barragan was arrested after officers tracked him from his home and pulled over his vehicle several days after the shooting, records reviewed by the San Antonio Express-News show.
Bar's license revoked
The Texas Alcoholic Beverage Commission initially suspended the Boom Boom Room’s liquor permit after the deadly shooting and later agreed to cancel it outright while examining whether the venue’s operations played a role in the violence. The move left the East Side spot without a liquor license and spotlighted regulators’ growing focus on after-hours operations, as reported by KTSA.
Legal implications
Barragan and Delarosa were both initially indicted on capital murder charges, along with aggravated assault counts. Prosecutors told jurors those indictments carried the possibility of life without parole or even the death penalty when the case was first filed. The matters were handled by the Criminal Trial Division in the 379th District Court, according to earlier reporting by KSAT.
Since the 2021 killings, victims’ families and community advocates have repeatedly called for tougher oversight of late-night venues and underground after-hours rooms. With Barragan now serving a life sentence, prosecutors said the case is a stark reminder of how quickly a bar fight can turn into a deadly scene once guns enter the mix.
