Tear gas is strictly prohibited for civilian use in Venezuela -- only police and military are legally permitted to possess it. But by 2018, the canisters had become disturbingly common in civilian hands. Theft from military stockpiles and corruption within the security forces fed a black market that put riot-control weapons in the possession of criminals and street gangs. In the months before the El Paraiso tragedy, tear gas attacks had struck a Caracas metro station, public gathering spaces, and even the offices of major media outlets like El Nacional and Globovision. Pro-government paramilitary groups called colectivos had used tear gas against opposition figures; in 2009, colectivos tear-gassed the Vatican's envoy after President Hugo Chavez accused the Catholic Church of meddling in Venezuelan politics. The weapon had migrated from crowd control into everyday violence.

The club had advertised the event for attendees over 18, though it also noted that minors could enter for an additional fee. A brawl broke out among students, and during the fight someone detonated a tear gas canister. What followed was chaos compressed into a sealed space. Family members of victims later said the doors were closed after the gas was released, trapping hundreds of panicked teenagers inside a building with barred windows. The gas filled the enclosed rooms rapidly. People surged toward exits that were too narrow and too few. Eight of those who died were younger than 18. The official causes of death were asphyxiation and polytrauma -- the clinical terms for suffocating and being crushed.

Survivors made repeated calls to 911 in the early morning hours. No emergency personnel arrived. By 2:30 a.m., nearly an hour after the stampede began, no ambulance or fire crew had reached the scene. Around 2:40 a.m., a single CICPC officer on routine patrol stumbled onto the situation. He initially drew his weapon and shouted before realizing what had happened and beginning to help evacuate survivors. Nazareth Duque, a survivor, recounted that three National Guardsmen stationed at the club entrance refused to help her and struck her in the face. The collapse of emergency response -- in a capital city, at a known public venue, for an event attended by hundreds -- pointed to a breakdown that extended far beyond this single night. Duque and other survivors estimated the actual death toll was higher than the official count, with some family members claiming as many as 34 people died.

Interior Minister Nestor Reverol announced that eight people had been detained, including two minors. One of those minors was identified as the person who detonated the tear gas canister. The club's owner was arrested for failing to ensure adequate safety measures and for violating laws prohibiting weapons in public establishments. Asphyxiation was confirmed as the cause of death for at least 11 of the 21 fatalities that investigators eventually documented. Reverol offered condolences on behalf of the government, but the tragedy exposed fault lines that condolences could not cover: a weapons proliferation crisis that put military-grade devices in the hands of teenagers, a nightclub operating with barred windows and insufficient exits, and an emergency response system that failed to show up at all. The El Paraiso stampede was not an isolated event. It was a convergence of systemic failures, each one individually survivable, together lethal.
