March 23, 1994. Tijuana. A dusty neighborhood called Lomas Taurinas.
Everything changed in a few seconds.
Luis Donaldo Colosio Murrieta was moving through a sea of people. He was the man everyone expected to be the next President of Mexico. Then, the music—a popular tune called "La Culebra"—was drowned out by a gunshot. Two, actually. One in the head, one in the abdomen.
Mexico stopped breathing. Honestly, for many, the country hasn't quite caught its breath since.
The Reformer Who Scared the System
You have to understand who Luis Donaldo Colosio Murrieta actually was to get why his death still stings. He wasn't just another suit from the PRI, the party that had gripped Mexico for decades. Sure, he was a product of that machine, but he was trying to fix it from the inside.
Basically, he was a bridge.
He grew up in Magdalena de Kino, Sonora. His dad was a meatpacker. He wasn't born into the elite. He studied at UPenn and in Vienna. He had this academic brain but a populist heart. By the time 1994 rolled around, the PRI was looking old and corrupt. Colosio was supposed to be the "new" face.

But he went off-script.
On March 6, 1994, standing in front of the Monument to the Mexican Revolution, he gave the speech. It’s the one every Mexican student knows. He said, "I see a Mexico hungry and thirsty for justice."
He wasn't just attacking the opposition. He was calling out his own party. The "system" didn't like that. Not one bit. Rumors started flying that President Carlos Salinas de Gortari was regretting his choice. People thought Manuel Camacho Solís might replace him. The tension was thick enough to cut with a knife.
Lomas Taurinas: The Day the Hope Died
Lomas Taurinas wasn't even on the original schedule for that day.
Why was he there? Some say it was a setup. Others say it was just bad planning. The security was light. Too light. As Colosio walked down those stairs into the crowd, he was vulnerable.
Mario Aburto Martínez was the guy they caught. A 23-year-old factory worker. He looked... normal. But the "lone wolf" theory started crumbling almost immediately.

How could one guy, in a crushing crowd, fire two shots from such different angles? The first hit the right side of his head. The second hit his left side, in the stomach. For years, people have argued that Aburto would have had to be a gymnast or a magician to pull that off alone.
The Second Shooter Theory Returns
In 2024 and 2025, the case took a wild turn. The Federal Attorney General's Office (FGR) started pointing fingers at someone else: Jorge Antonio Sánchez Ortega.
Sánchez Ortega wasn't a factory worker. He was an agent for CISEN, Mexico's old intelligence agency.
Guess what? He was at the scene. He had Colosio's blood on his jacket. He tested positive for gunpowder residue. Back in 1994, he was let go. Now, prosecutors are saying he was the second shooter. They’re even alleging that Genaro García Luna—who later became the security chief and is currently in a U.S. prison—helped him escape Tijuana that night.
It’s like a spy novel, but people actually died.
Why We Still Care About Luis Donaldo Colosio Murrieta
You might wonder why a 30-year-old murder case still makes the front page in 2026.

It’s because Mexico is still dealing with the same ghosts. Corruption. Impunity. The feeling that the "real" truth is always hidden behind a curtain. Colosio represented a version of Mexico that never happened. A "what if" that haunts the national psyche.
His son, Luis Donaldo Colosio Riojas, is a major political figure now. He’s been the Mayor of Monterrey and a Senator. People look at him and see his father. In early 2024, he actually asked for a pardon for Mario Aburto. He said he wanted "compassion" and for the country to heal.
But the government didn't listen. They reopened the case instead.
Some see this as a genuine search for justice. Others think it’s just politics—using a dead hero to attack old rivals. Honestly, it’s probably a bit of both.
The Facts We Can't Ignore
- The Weapon: A .38 Special revolver.
- The Sentence: Mario Aburto was sentenced to 45 years, later reduced to 30. He was supposed to be out by now, but legal battles kept him in.
- The Mystery: The "Aburto Replacement" theory. Many Mexicans believe the man arrested in the park wasn't the man who showed up in court. They say he looked different, walked different.
- The Legacy: The PRI never recovered. They lost the presidency in 2000 for the first time in 71 years.
How to Understand the Colosio Case Today
If you want to understand the modern Mexican state, you have to look at this case. It's the "JFK moment" for Mexico.
To dig deeper into the actual evidence, look for the 2000 Special Prosecutor's report—it's thousands of pages long and tries to debunk the conspiracy theories. Then, compare it to the FGR's 2024 statements. The contradictions are where the truth usually hides.
Actionable Steps for History Buffs and Analysts:
- Watch the footage: The video of the shooting is public. Watch the movement of the crowd. Notice the lack of a security perimeter.
- Read the "March 6 Speech": It’s the blueprint for what Colosio wanted for Mexico. It explains why he became a target.
- Follow the Aburto legal updates: The Supreme Court of Justice in Mexico is still debating his release. His status is a barometer for how the current administration views the "historical truth."
Luis Donaldo Colosio Murrieta didn't just leave a family behind; he left a void. Whether it was a lone madman or a state-sponsored hit, the result was the same: a path not taken.
