Griselda Blanco didn't just leave behind a trail of bodies and a mountain of cocaine; she left a target on the backs of her own children. It’s the part of the story that makes people uncomfortable. Most folks know her as "The Black Widow" or the "Queen of Cocaine," but the tragedy of her family is where the glitter of the Netflix-style glamorization completely falls apart. If you're asking who killed Griselda Blanco sons, you’re digging into a cycle of revenge that spanned decades and crossed multiple continents. It wasn't just one person or one hitman. It was a whole ecosystem of enemies.
The reality is grim. Three of her four sons—Dixon, Uber, and Osvaldo—are dead. Only Michael Corleone Blanco, the youngest, survived to tell the story, and even his life has been shadowed by the constant threat of a bullet. The street has a long memory.
The Violent End of the Trujillo-Blanco Trio
Griselda’s first three sons were born to her first husband, Carlos Trujillo. They were raised in the heart of the trade. They weren't just bystanders; they were active participants in the business their mother built. This meant that when the law finally caught up to Griselda, and more importantly, when her rivals felt it was safe to strike, her sons were the easiest targets.
Uber Trujillo was the first to go. He was murdered in Colombia while his mother was still serving time in a United States federal prison. The hit was professional. It was calculated. Most experts on the Medellin era, including journalists like Guy Gugliotta, suggest that Uber’s death was a direct message to Griselda. It was about "accountability" in the underworld. When you live by the sword, your family often pays the interest on your debts.
Osvaldo "Ozzie" Trujillo came next. His death was even more public. He was gunned down in a nightclub in Colombia. Imagine the scene: loud music, expensive bottles, and then the sudden, rhythmic pop of gunfire that silences everything. Ozzie was flashy, much like his mother, and that flash made him an easy mark. The assassins were reportedly linked to the very cartels Griselda had once dominated or feuded with—likely remnants of the Medellin power structure that had shifted in her absence.
Dixon Trujillo and the Mystery of the Eldest
Dixon’s fate is often debated, but the consensus among law enforcement and those who followed the Blanco saga is that he, too, met a violent end shortly after being released from prison. Some accounts suggest he was murdered in a business dispute, while others believe it was simply the same "cleansing" process that took his brothers.

It’s important to understand the climate of 1990s Colombia. This wasn't just about Griselda. It was about the transition of power. When the big bosses went to jail or died, their heirs became liabilities. The rivals didn't want a second generation of Blancos rising up to reclaim the throne. By eliminating the sons, the enemies of the Godmother were effectively cauterizing the wound. They were making sure the Blanco dynasty ended with her.
Why the Question of Who Killed Griselda Blanco Sons is Complicated
You can't point to a single name like you're solving a Clue board game. It wasn't "Colonel Mustard in the Library." It was the Medellín Cartel. It was the PEPES (People Persecuted by Pablo Escobar). It was disgruntled former associates who had been burned by Griselda’s notorious paranoia.
Griselda was famous for killing her husbands and killing anyone who owed her money—or anyone she owed money to. That creates a massive list of people with a motive. When she was deported back to Colombia in 2004, she was a woman without a country and without protection. Her sons were her only legacy, and in the world of narco-trafficking, killing a rival's children is the ultimate act of "settling the score."
The Survival of Michael Corleone Blanco
Michael Corleone Blanco is the outlier. Named after the Godfather himself, he grew up while his mother was behind bars. He has been incredibly candid about the fact that he survived multiple assassination attempts. He lost his father, Dario Sepulveda, to his mother’s own orders. Talk about a complicated family dynamic.
Michael eventually pivoted. He realized that staying in the "family business" was a death sentence. He moved into the public eye, appearing on reality TV shows like Cartel Crew and launching his own lifestyle brand. By becoming a public figure, he created a different kind of protection for himself. It’s harder to disappear someone when they’re on camera every week. But even he would tell you that the shadow of who killed Griselda Blanco sons looms over every move he makes.

The Role of the Ochoa Clan and the Medellin Shift
While Griselda was a pioneer, she was also a loose cannon. The Ochoa brothers and other high-level Medellin figures found her unpredictability bad for business. While there is no smoking gun linking a specific Ochoa order to the Trujillo-Blanco deaths, the environment they controlled was one where such hits were common and often sanctioned by the ruling council of the time.
The "Motosicarios" (motorcycle assassins), a tactic Griselda ironically claimed to have invented, were the ones who ultimately took out most of her family. It’s a haunting bit of poetic justice that the very method of execution she popularized was the one used to dismantle her bloodline.
The Geography of Revenge
The hits didn't happen in Miami. They happened in Medellin and surrounding areas. This is significant. It shows that even though Griselda built her empire in the States, her sins followed her back to the soil of Colombia. The "Cold War" of the cartels never really ended; it just changed shapes. When the sons returned to Colombia, they were walking into a graveyard they didn't know was already dug for them.
- Uber: Killed in Medellin during a drug deal gone wrong, or so the official report says.
- Osvaldo: Executed in a crowded space to maximize the message.
- Dixon: Perished shortly after his return to the streets.
The Godmother's Final Chapter
Griselda herself was killed in 2012. She was 69. She was leaving a butcher shop in Medellin when a man on a motorcycle—there it is again—shot her twice in the head. It was a mirror image of the hits she had ordered hundreds of times. By the time she died, she had already outlived three of her four children.
The tragedy isn't just in the deaths; it's in the inevitability. If you look at the court documents from the 1980s, federal prosecutors practically predicted this. They saw a woman who was burning every bridge she crossed. You can't be the "Queen" of a blood-soaked industry and expect your princes to inherit a peaceful kingdom.

Moving Beyond the Netflix Version
If you’ve watched the glossy TV specials, you might think there’s some grand conspiracy or a single villain. Honestly, that’s just not how the underworld worked back then. It was a chaotic, fractured mess of vendettas. The killers were likely low-level "sicarios" (hitmen) working for any number of mid-level bosses who wanted to settle an old debt or make a name for themselves by "killing a Blanco."
The names of the actual shooters are lost to the archives of Colombian police stations that were often underfunded or compromised. But the why is clear. The sons died because their mother’s name was a currency that eventually lost all its value and became a liability.
What You Should Do Next
To truly grasp the scale of the violence that claimed Griselda Blanco's sons, you should look into the history of the Medellin Cartel's internal purges of the early 1990s. Reading The Kings of Cocaine by Gerard de Groot or the investigative work of Colombian journalists from El Espectador provides the necessary context that TV shows skip.
If you're researching this for a project or out of genuine interest in true crime, focus your energy on the transition of power between 1989 and 1993. That four-year window is when the old guard, including the Blanco family, was systematically dismantled. You can find declassified DEA intelligence reports through the Freedom of Information Act (FOIA) that detail the "cleansing" of the Blanco organization. Understanding the specific mechanics of the Medellin "office" (La Oficina de Envigado) will give you the clearest picture of how these hits were coordinated and why no one was ever truly brought to justice for them.
