Lampa massacre: ignored alerts and system failures before Operation Tokyo
Former security minister Trinidad Steinert reveals that the UAF alerted the Prosecution to the Tren de Aragua network three months before the five murders in Lampa.
Three months of silence: the report that arrived before the massacre
Three months before five people were murdered in a plot in Lampa, the Financial Analysis Unit (UAF) had already sent the national prosecutor a financial intelligence report with suspicious transaction reports linked to the same network that would carry out the killings. This is detailed by Trinidad Steinert, former Minister of Public Security, in an analysis accessed by t13.cl and titled "Alerts, omissions and the advance of organised crime in Chile".
The shooting occurred on 16 July 2024 during an unauthorised party in Lampa, in the Metropolitan Region. Four men and one woman were killed in gunfire. The event had been organised without permission and without paying the "vaccine" that Tren de Aragua demanded from nightclub promoters. What followed was called the Lampa massacre, the bloodiest settlement of accounts by transnational organised crime in the recent history of the country, according to Steinert's own report.
The money trail that no one followed in time
The investigation resulting from the crime culminated almost two years later with "Operation Tokyo", a major operation executed in June 2026 that dismantled part of the Tren de Aragua structure and included the detention of banking executives. Among those detained was José Carlos Pérez Asencio, the leading banking executive involved in the network, arrested on 2 June 2026.
According to Steinert's analysis, the UAF sent at least four financial intelligence reports to the national prosecutor between April 2024 and May 2026 regarding this organisation. Despite this, the network that between 2022 and 2025 laundered more than 75 billion pesos continued to operate, expand and kill.
The formal investigation that finally dismantled the structure did not begin with those financial reports. It was a mobile phone dropped in the mud during the gunfire that gave the police the necessary evidence to begin the process. The phone belonged to Bárbara Hernández, known as "Barbie", a collector for the gang and witness to the shooting, who lost it while fleeing the scene.
"Chance made the difference"
The former minister is careful to establish the limits of institutional responsibility. "In the strict sense, it cannot be affirmed that the Lampa massacre was avoidable", she writes in her analysis. However, she adds that "a financial intelligence report describes flows of money, it does not announce a homicide", and that the documented chronology opens a window that cannot be ignored.
"The first UAF report reached the National Prosecution in April 2024 and the five murders occurred in July 2024. Between one event and the other there were three months in which a formal investigation opened —a RUC, proceedings, account interruptions, detentions— would have placed pressure on the structure that finally carried out the killings", writes Steinert.
The former state secretary emphasises that this is not about attributing "magical prevention capabilities" to the system, but rather confirming that "the same evidence that would later dismantle the network was already there, written and dispatched, on a desk at the National Prosecution" before the five murders occurred.
Her conclusion about system functioning is direct: "The financial intelligence system had seen the network; the criminal investigation system only touched it when chance left a phone in the mud. The difference between anticipating and reacting, in this case, was made by chance".
A crack in public security
For Steinert, the Lampa massacre is not just a crime. It is the symptom of an institutional failure and, consequently, a crack in Chile's public security. Her report detailed the money trail and the role of the actors involved in the money laundering scheme, as well as the path that financial alerts took from their detection by the banking system to their arrival at the Public Ministry.
The former minister concludes that "pursuing illicit money is not a complementary task, but an essential component of an effective strategy against organised crime". The analysis was presented this week in her role as a public security researcher and constitutes the first formal report on the omissions and alerts surrounding the case before and after the massacre.
