When Netflix released Griselda in early 2024, audiences worldwide became captivated not just by Sofia Vergara’s stunning transformation into one of history’s most feared drug lords, but by the explosive and ultimately fatal relationship at the heart of the story — the marriage between Griselda Blanco and her third husband, Dario Sepulveda. For millions of viewers searching “Dario Griselda” online, the question was the same: how much of this was real, and how did it actually end?
The answer is more disturbing than the show suggests.

| Died | 1983, Medellín, Colombia |
| Cause of Death | Assassination (gunshot) |
| Married | Griselda Blanco (1978–1983) |
| Son | Michael Corleone Blanco |
| Portrayed by | Alberto Guerra (Netflix’s Griselda) |
| Occupation | Drug dealer, hitman |
A Hitman Who Fell for His Target
Dario Sepulveda was a hitman — a hired assassin known in cartel circles for his ability to get the job done quietly and without hesitation. That reputation was precisely why he was contracted in 1978 to kill Griselda Blanco. He did not complete the job. Instead, he fell in love with her, and the two were married that same year.
It was, from the beginning, a relationship built on violence — two people from the darkest corners of the Colombian drug trade who somehow found something in each other that neither had found anywhere else. Their son, Michael Corleone Blanco, was born on August 5, 1978, in Medellín, Colombia — named after the fictional Godfather character in a choice that, given his mother’s reputation, felt less like a cinematic tribute and more like a statement of intent.
The Marriage That Could Not Survive Griselda Blanco
For a few years, Dario Sepulveda occupied a unique position in the world of Griselda Blanco — not just a husband, but a man who understood exactly what she was capable of and stayed anyway. But as Blanco’s cocaine empire expanded through Miami in the late 1970s and early 1980s, the relationship began to fracture under the weight of her escalating paranoia, erratic behavior, and total obsession with power.
Dario grew increasingly concerned that Griselda had become an unfit mother, too consumed by the dangerous cocaine business to properly care for their son. After a heated argument, he made the decision that would ultimately cost him his life — he took Michael and returned to Colombia, away from the violence and instability of Miami.
Dario Sepulveda and Griselda married in 1978 and split in 1983, the same year he was killed. He returned to Medellín taking their five-year-old son, Michael, with him — wanting to shield the child from a life of crime. It was an act driven by fatherly instinct. Griselda Blanco interpreted it as something else entirely — a direct challenge to her authority.
The Assassination — And the Witness Who Could Never Forget It
What happened next is one of the most harrowing chapters in the entire Griselda Blanco story — and one that the Netflix series, for all its unflinching brutality, could only partially convey.
According to the Miami New Times, Dario was killed by men pretending to be police officers in Medellín in 1983. Two of Griselda’s associates — former smuggler Max Mermelstein and ex-hitman Jorge “Rivi” Ayala — subsequently told law enforcement that she was the one who ordered the hit.
The execution was carried out with their son Michael present. The assassins dressed as police, handcuffed Dario, and when he attempted to run, opened fire. Little Michael was screaming and ran over to embrace his father, but by the time he reached him, Dario was already dead. The child was five years old.
It was the act that, more than any other in Griselda Blanco’s long and violent career, cemented her nickname — the Black Widow. All three of her husbands — Carlos Trujillo, Alberto Bravo, and Dario Sepulveda — were allegedly killed on her orders, earning her the nickname that followed her for the rest of her life.
How Alberto Guerra Brought Dario to Life on Screen
In the Netflix series, actor Alberto Guerra plays Dario Griselda with a complexity that goes beyond the simple “victim husband” narrative. In an interview with Men’s Health, Guerra described his interpretation of the character’s arc as a kind of inverted soap opera: “Dario lost her to power. He didn’t lose her to another man.” That framing captures something essential about the real Dario Sepulveda — a man who was not innocent, who was himself a product of the same violent world that ultimately destroyed him, but who, in his final act, was simply trying to save his son.
The Son Left Behind
After his father’s death, Michael Corleone Blanco returned to the United States to live with Griselda in Irvine, California. He later founded the hip-hop label Xtorxion Records and the streetwear and lifestyle company Pure Blanco. He married Marie Ramirez De Arellano in 2021, and the couple has a daughter, Faith.
Michael has spoken publicly about his father’s death on multiple occasions — always with the weight of a man who watched it happen as a five-year-old child and never fully left that moment behind.
