The dirt is dry in Colinas de Santa Fe, a stretch of land near the port of Veracruz. For years, it looked like just another vacant lot, the kind of place you’d drive past without a second thought. But under the surface, it held a secret that redefined how we talk about mass graves in mexico. Between 2016 and 2019, search parties led by mothers—not the police—uncovered nearly 300 bodies there. It was a massive, horrific discovery that shifted the national conversation from "isolated incidents" to a systemic crisis.
When people talk about Mexico, they usually think of beaches or food. Honestly, they don't want to think about the fosas clandestinas. But you can't understand modern Mexico without looking at the ground beneath your feet. Since 2006, when the government launched its official "War on Drugs," the number of hidden burial sites has exploded. We aren't just talking about a few dozen locations. Data from the National Search Commission (CNB) suggests there are thousands of these sites scattered across almost every state.
It’s heavy. It’s dark. But it’s the reality of a country where over 115,000 people are currently listed as disappeared.
The map of the missing
Where do you find mass graves in mexico? Everywhere. Seriously. While some regions like Tamaulipas, Jalisco, and Veracruz are notorious, the geography of clandestine burials follows the shifting lines of cartel influence and territorial disputes. It's not just the cartels, though. Human rights organizations like Prodh (Centro de Derechos Humanos Miguel Agustín Pro Juárez) have documented cases where state actors were either complicit or directly involved.
Take the case of Tetelcingo in Morelos. This wasn't a cartel site. It was a pit used by the state prosecutor's office to dump unidentified bodies, many of which were buried with their clothes on, hands tied, and without proper forensic records. It exposed a terrifying truth: the line between "criminal" graves and "official" mismanagement is often blurry.
In Jalisco, the numbers are staggering. The state has become a flashpoint for the Jalisco New Generation Cartel (CJNG). In places like Tlajomulco de Zúñiga, authorities frequently find "multiburials" in suburban backyards. You've got families living next door to houses where dozens of bodies are being pulled from the patio. It’s surreal and heartbreaking.

Why the government can't keep up
The forensic crisis is the part nobody likes to talk about. Even when a grave is found, that’s just the start of a nightmare. There’s a massive backlog. We’re talking about over 50,000 unidentified remains sitting in morgues, containers, and temporary graves.
The system is broken.
Basically, the rate at which bodies are found far outpaces the capacity of labs to process DNA. Forensic experts are overworked, underfunded, and sometimes, they're just scared. If you’re a technician in a high-conflict zone, identifying a body might make you a target. That’s the reality.
- Forensic SEMEFO (Servicio Médico Forense) facilities in states like Guerrero have literally overflowed in the past.
- DNA databases are fragmented; a mother in Michoacán might have her DNA on file there, but if her son is found in a mass grave in Sonora, the systems might not "talk" to each other.
- The National Forensic Oversight Institution was created to fix this, but progress is slow. Kinda like trying to empty the ocean with a spoon.
The Colectivos: Mothers with shovels
If it weren't for the colectivos, most mass graves in mexico would stay hidden. These are groups of families—mostly mothers—who have lost children. They don’t wait for the police anymore. They bought their own probes, shovels, and GPS trackers.
They go into the bush. They stick a metal rod into the earth, pull it out, and smell the tip. If it smells like decay, they start digging.

Ceci Flores, the founder of Madres Buscadoras de Sonora, is a name you should know. She’s been searching for her sons for years. She’s faced death threats, she’s been forced into displacement, and yet she keeps digging. These women have become amateur forensic experts by necessity. They know the soil types, they know how to identify a femur versus a piece of wood, and they know how to navigate the complex social codes of cartel-controlled territories.
It’s a bizarre kind of bravery. They aren't looking for "justice" in the way we usually think about it. Most of them have given up on seeing the killers behind bars. They just want a body to bury. They want a place to pray.
The technology of the hunt
While the shovels do the heavy lifting, technology is starting to play a bigger role. Researchers are using LiDAR (Light Detection and Ranging) to spot depressions in the ground that might indicate a grave. It’s the same tech used to find Mayan ruins, but now it’s being used to find the victims of the 21st century.
There's also the "Grave Registry" project. This is an effort by NGOs to map every single mention of a clandestine grave in local news reports. Why? Because the official government numbers often lag behind or "miss" smaller sites. By cross-referencing news reports with official data, researchers get a much clearer—and much grimmer—picture of the scale.
Misconceptions about who is in the graves
People often assume everyone in a mass grave was "involved" in something. That's a dangerous lie. It’s a way for society to look away.

The truth is much more complicated.
- Migrants from Central and South America are frequently targeted. They are kidnapped for ransom, and if they can't pay, they end up in a pit. The San Fernando massacre in Tamaulipas, where 72 migrants were murdered, is the most famous example, but it’s not the only one.
- Innocent bystanders caught in crossfire or "mistaken identity" cases.
- Low-level lookouts or "halcones," often teenagers coerced into service.
- Activists and journalists who poked the wrong nest.
When you find a grave with 50 people, you aren't looking at 50 criminals. You're looking at 50 families whose lives have been permanently dismantled.
What needs to happen next
Fixing the crisis of mass graves in mexico isn't just about digging. It’s about the entire pipeline of justice. The "crisis of disappearances" is a direct result of near-total impunity. If you can kill someone and hide the body with a 98% chance of never being caught, why would you stop?
The Mexican government has made some strides. The creation of the Extraordinary Mechanism for Forensic Identification (MEIF) was a big deal. It’s supposed to bring in international experts to help clear the backlog. But it needs teeth. It needs money. And it needs the political will to admit that the problem is as bad as the mothers say it is.
Actionable Steps for Awareness and Support
If you want to move beyond just reading about this, there are concrete ways to support the efforts on the ground. This isn't just a "Mexico problem"—the arms and money fueling this violence often cross borders.
- Support the Colectivos: Groups like Madres Buscadoras de Sonora or Hasta Encontrarte often rely on private donations for gas, shovels, and basic supplies. Following them on social media helps amplify their discoveries, which provides a layer of protection through visibility.
- Follow Independent Journalism: Outlets like Pie de Página and Quinto Elemento Lab do the deep forensic reporting that mainstream media often skips. Their "A Donde Van Los Desaparecidos" project is the gold standard for tracking this issue.
- Pressure for Forensic Aid: International cooperation is vital. Support policies that provide technical forensic training and equipment to Mexican laboratories through international aid programs.
- Acknowledge the Scale: Avoid the "they must have been involved" narrative. Recognizing the victims as humans is the first step toward demanding the systemic changes needed to stop the creation of new graves.
The reality of mass graves in mexico is a wound that won't heal until the last person is brought home. It's a long road, but the families aren't stopping. Neither should the world's attention.
