Hernan Ricardo Lozano and the Colgate Tube That Killed 73

By Theo Marchetti · September 12, 2026

The 1976 bombing of a Cuban airliner wiped out a national sports team, but the key testimony was extracted in a Caribbean police station under conditions the record doesn't explain.

Seventy-three people died when Cubana de Aviación Flight 455 vanished into the sea on October 6, 1976. Among the dead was the entire Cuban national fencing team, a collective execution that turned a scheduled flight from Barbados to Jamaica into a mass grave.

What follows is not a transcript of the investigation, but the archive's curated description of a single deposition. This summary establishes the narrow window through which we are permitted to view the aftermath of the massacre.

The Eight-Day Silence

The inquiry into the bombing was led by Dennis Ramdwar, the Deputy Commissioner of Police in Trinidad and Tobago, the southernmost archipelagic country in the Caribbean. Ramdwar's role was to manage the local legal machinery of an investigation that, by its nature, spanned international borders and targeted a state-owned entity.

The first rupture in the case is the behavior of Freddy Lugo, the man the record identifies as the primary informant. According to the record, "Freddy Lugo initially denied knowledge of the crash." For eight days, Lugo maintained a wall of silence while the wreckage of the Douglas DC-8 settled on the ocean floor. Then, with a suddenness that defies the logic of spontaneous memory, the wall collapsed. The record states that "eight days later, Lugo tells Ramdwar that he is convinced that Lozano placed the bomb on the aircraft."

This transition is where the official narrative begins to fray. The public record establishes that Lugo claimed Ricardo Lozano, the man accused of planting the device, had told him twice that he intended to blow up a Cubana aircraft as the two traveled to the airport prior to the bombing.

The trajectory of Lugo's cooperation—from absolute denial to specific accusation in exactly one week—is a pattern recognized by anyone who has spent time in the Stasi archives. People do not usually find their conscience on a precise eight-day schedule. The desk's reading is that Lugo's testimony was the result of a negotiated settlement or external coaching. He did not remember; he was told what to remember.

The Verisimilitude of Toothpaste

Once Lugo provided the name, the focus shifted to Hernan Ricardo Lozano, the individual the record positions as the operative. Lozano did not merely confess to the act; he provided the technical specifics of the device's construction. In a separate interview with Ramdwar, Lozano detailed how a "certain chemical is filled in a tube of Colgate toothpaste after the toothpaste is extracted" to construct the bomb.

Colgate, the global brand of toothpaste, provided the physical housing for the explosive. By using a common household item, Lozano ensured the device would pass through security undetected. However, the specificity of the tube is the only technical detail provided. The record is conspicuously silent on the nature of the "certain chemical" itself.

This is a classic intelligence play: provide a vivid, mundane detail—the toothpaste tube—to create a sense of authenticity, while keeping the actual source of the specialized explosive chemicals obscured. If you give a police officer a brand name he recognizes, he stops asking about the molecular composition of the trigger. The pattern suggests that the Colgate tube serves as verisimilitude, a prop designed to distract from the professional origin of the munitions.

A Local Performance

Cubana de Aviación, the government-owned flag carrier of Cuba, was the target of a strike that required more than just a tube of toothpaste. To successfully bomb an international flight, an operative needs funding, logistical support, intelligence on flight manifests, and a guaranteed exit strategy. Yet, the record we have is a local police deposition conducted by a Deputy Commissioner in Port of Spain.

There is a profound irony in the geography of this file. The bombing was an act of international terrorism targeting a sovereign state's airline, yet the primary evidence is processed through the Trinidad and Tobago Ministry of National Security. By funneling the investigation through a local police department, the architects of the bombing created a buffer of plausible deniability.

If the investigation is treated as a local criminal matter involving a rogue individual like Lozano and a witness like Lugo, it never becomes a diplomatic crisis involving intelligence agencies. The focus remains on the police station in Trinidad rather than the command centers in Langley or elsewhere. The desk's reading is that this entire investigation was a performance of local jurisdiction intended to mask the involvement of a foreign intelligence agency.

The Peripheral Record

This deposition does not exist in a vacuum. It is held within a wider collection of Top Secret CIA and NSA strategic documents, sitting alongside memos on Soviet missile sites and SIGINT histories. The presence of a local police statement in a high-level intelligence archive is a tell. It is not there because it is the core of the case; it is there because it is the authorized version of the case.

Lozano and Lugo are not the protagonists of this story; they are the insulation. They are low-level assets used to protect the actual architects of the operation from the legal record. By placing the blame on a man with a toothpaste tube, the agency responsible for the massacre ensures that the operational directives—the orders, the payments, the coordination—remain classified.

If the shape of this file is what it appears to be, we are looking at a peripheral record curated to provide a plausible narrative for the archive. The real story is in the gaps: the missing chemical analysis, the source of Lozano's funding, and the identity of the handler who told Lugo when to stop denying and start talking.

The pattern is clear. The 73 passengers of Flight 455 were not killed by a lone actor with a hobbyist's interest in chemistry. They were killed by a professional operation that used a Caribbean police department as its cleaning service. A full release of the associated files would show that Lozano was not the architect, but the expendable edge of a blade held by a much larger hand. Those who paid for the toothpaste tubes are the ones the redactions are still protecting.
