A man has been sentenced to life in prison for a 2021 shooting that left three people dead outside an illegal after-hours bar in east San Antonio. Daniel Barragan was convicted of opening fire with an assault-style weapon into a crowd of people leaving the 'Boom Boom Room' following a disturbance between two women that escalated. Barragan and another man, Eduardo Delarosa, retrieved firearms and began shooting, killing three and wounding two others before Barragan fled the scene.

Why it matters

This case highlights the dangers of illegal after-hours establishments and the ongoing challenges of gun violence in San Antonio, which has seen a rise in homicides in recent years. It also underscores the need for stricter regulation and enforcement around unlicensed bars and clubs to protect public safety.

The details

According to prosecutors, the incident began as a fight between two women with a prior history at the 'Boom Boom Room,' an illegally operated after-hours bar. The altercation escalated as more individuals became involved, eventually moving outside the bar. Barragan and Delarosa then retrieved firearms from their vehicles, with video evidence showing Barragan firing an assault-style weapon directly into the crowd of people leaving the bar. Barragan's gunfire killed Dan Edward Martinez Jr. and siblings April Rodriguez and Mauro Rodriguez, and wounded two others before he fled the scene. Delarosa pleaded guilty to aggravated assault with a deadly weapon and was sentenced to 15 years in prison.

  • The shooting occurred in August 2021.
