In January 2023, a United States federal grand jury returned a superseding indictment against Joaquín Guzmán López and Ovidio Guzmán López, sons of the imprisoned cartel leader Joaquín “El Chapo” Guzmán, along with other alleged associates of the faction known as Los Chapitos. The charges included drug trafficking, murder conspiracy, kidnapping, and torture. Buried within that filing were allegations that would separate this prosecution from nearly every other cartel case in recent memory: accounts of physical abuse, electrical torture, simulated drowning, forced drug administration, the use of exotic animals against captives, and the deliberate public display of mutilated bodies. Federal prosecutors did not present these acts as random brutality.
They described them as a deliberately constructed system of control built to protect one of the most profitable criminal enterprises in human history. The organization at the center of these allegations did not emerge overnight. Its roots reach back to the mountainous region of northwestern Mexico known as the Golden Triangle, where the states of Sinaloa, Durango, and Chihuahua meet, a geography that produced drug traffickers from at least the 1970s. The original architect of the modern Mexican drug trade was Miguel Ángel Félix Gallardo, who built the infrastructure that successors would inherit and expand.
When he was arrested in 1989, the organization fragmented, and over the following decade, El Chapo Guzmán rose to dominate what became the Sinaloa Cartel. By the mid-2000s, the DEA described it as the most powerful drug trafficking organization in the Western Hemisphere, moving cocaine, heroin, and methamphetamine across the border at a scale that dwarfed its rivals. El Chapo’s own history was marked by escapes and recaptures. Arrested in 1993, he escaped from prison in 2001, was recaptured in 2014, escaped again in 2015 through a tunnel beneath his cell, and was finally extradited to the United States in January 2017.
His 2019 conviction in a Brooklyn courtroom resulted in a life sentence plus thirty years. But his removal did not end the cartel. It created a succession problem. His sons did not inherit the organization intact; they emerged as a faction known as Los Chapitos, navigating internal power disputes with long-time Sinaloa leadership, managing relationships with rivals, and facing accelerating pressure from US and Mexican law enforcement.
Federal prosecutors would later argue that this faction adopted an approach significantly more aggressive and more willing to deploy violence internally than previous Sinaloa leadership had been. To understand why an organization like Los Chapitos allegedly used torture as an operational tool, one must understand what a criminal enterprise of this scale is protecting. By the time federal indictments began describing it in detail, the cartel’s fentanyl operation alone was generating revenue in the billions of dollars annually. Protecting that revenue from law enforcement, rivals, and internal defection required mechanisms of control that made disloyalty feel catastrophically dangerous.
Investigators who have studied cartel structures describe internal violence as serving four distinct functions: interrogation to extract intelligence about who has cooperated with authorities; punishment to make an example of individuals who endangered the cartel; identification to determine which network members have been cooperating with law enforcement; and deterrence to create a culture in which the consequences of betrayal are so well understood that potential defectors never take the first step. Federal indictments allege that all four functions were built into the faction’s operations as deliberate objectives, not incidental outcomes of individual rage. The first method documented in federal materials was physical and chemical coercion during interrogation. This was the most frequently alleged method, the baseline tool operatives reached for first when they needed someone to break.
According to federal materials, captives were subjected to sustained physical abuse using common tools, and chemical irritants were applied directly to them during sessions. The purpose was information extraction, getting captives to identify which cartel network members had been talking to law enforcement and how badly operational security had been compromised. The occasion was almost always suspected disloyalty: a shipment seized at a time suggesting a tip-off, a rival faction moving on a location only insiders knew about, or law enforcement showing up where it should not have known to look. Jose Antonio Munoz Parra, Mario Nungaray Bobadilla, and Giovanni Hurtado Vicente are named in federal materials in connection with internal cartel disputes.
According to the indictment, they were detained, interrogated, and subsequently killed. The second method, electrical torture, drew particular prosecutorial attention because of what it suggested about the deliberateness of the cartel’s approach. Federal materials document accounts of electrical devices used on captives at Los Chapitos controlled facilities. Electrical methods serve a specific function: the pain is intense and immediate, but also precise.
It can be applied, stopped, and reapplied in a controlled sequence that pure physical coercion cannot replicate. The psychological dimension compounds the physical one, inducing a sustained state of anticipatory terror that degrades a captive’s ability to think strategically. What made the electrical allegations particularly significant to prosecutors was the detail that individuals subjected to these methods were in at least some cases subsequently killed after the interrogation concluded, elevating the allegation from evidence of torture into evidence of a system. The third method was simulated drowning, forcing water over a restrained captive’s face and airways to trigger the body’s involuntary suffocation response.
Unlike physical beating or electrical methods, it leaves no visible marks. It operates almost entirely in the psychological dimension, exploiting the most primal fear the human body carries and inducing absolute panic that most people cannot sustain for more than a few seconds before their resistance collapses. Investigators note that psychological methods like this are typically deployed alongside physical ones because the combination is significantly more effective than either approach alone. Federal materials describe its use at the same private ranch facilities that appear repeatedly throughout witness accounts.
The fourth method separated this indictment from virtually every other cartel prosecution. Federal documents allege that captives were forcibly administered fentanyl to test the potency of drug batches before distribution. Fentanyl is roughly one hundred times more potent than morphine by weight, and the DEA has documented that as little as two milligrams can be lethal in a person without opioid tolerance. The Los Chapitos fentanyl operation was producing at industrial scale, generating billions annually, and according to the indictment, captives were being used as the final quality control step in that supply chain.
An unnamed female captive is referenced specifically in connection with this allegation, described as an individual subjected to forced fentanyl administration at a location under cartel control. Prosecutors cited her case as direct evidence of the operational link between the torture practices and the drug production infrastructure. It placed the violence not alongside the trafficking operation, but inside it. The fifth method involved the use of exotic animals, specifically tigers and other large predators, kept at cartel ranches.
Federal materials and investigative reporting both reference the presence of these animals at secured rural compounds. Allegations connect their presence to violence against individuals held at the same properties. Maintaining large predatory animals at remote facilities requires resources, staffing, and institutional impunity that tells investigators something about the organization’s operational confidence. The sixth and final method was postmortem mutilation and the deliberate public display of victims, designed not for the person it was done to, but for everyone else.
Human rights organizations have recorded cases in Sinaloa in which bodies were left in public locations, on roadsides, in front of municipal buildings, in conditions intended to communicate a message. The case of Hugo Hernández became one of the most widely cited examples, involving staged public violence calculated to reach the widest possible audience. These displays sent territorial messages to rival factions, warned municipal officials and law enforcement against cooperation, and deterred journalists. Journalists have documented the behavioral changes that follow: the drop in tips, the withdrawal of witnesses, the sudden silence from local media.
One unnamed Mexican law enforcement officer is also referenced in federal materials, demonstrating that the cartel’s alleged practices were not confined to rival members or suspected informants. Connecting all six methods is the infrastructure that made them possible: the private ranches. These remote properties offered the cartel time and silence. In a city, moving a detained individual attracts attention; sounds carry through walls; law enforcement response times are measured in minutes.
At a remote ranch, none of those constraints apply. A captive who understands they are hours from the nearest town is already in a profoundly compromised state. The isolation is a method in its own right. Federal investigators described these properties not as incidental locations, but as maintained, staffed, operational infrastructure built and sustained specifically to make the alleged crimes possible.
The timeline of when these practices intensified matters. In the period following El Chapo’s extradition in 2017, Los Chapitos moved to consolidate operational control against a backdrop of intensifying conflict with the Jalisco New Generation Cartel, which was expanding into territories the Sinaloa Cartel had previously controlled. The combination of internal succession pressure and external territorial threat created conditions in which internal coercion served the faction’s interests directly. According to witness accounts, the use of coercive interrogation at ranch facilities increased during this period, and the fentanyl operation expanded during the same time frame, with the DEA documenting a dramatic increase in fentanyl seizures at the border.
Federal prosecutors presented this convergence as evidence of a coherent organizational response, not chaos, but strategy. The ability to conduct operations of this alleged scope also required institutional corruption. The alleged ability to operate ranch facilities, maintain exotic animals, and conduct public violence with limited law enforcement response required the cooperation or willful inaction of institutional actors. Federal prosecutors and journalists have documented allegations of cartel payments to municipal police and local officials.
Mexico’s own statistics show that less than 2% of crimes result in a conviction, and in Sinaloa specifically, years of impunity have been documented. That impunity is not simply a failure of capacity; it is a manufactured condition produced by cartel money and threats over decades. The difficulty victims and witnesses face in coming forward is part of why the full scope of these allegations took years to build into a federal indictment. Witnesses typically cooperate under conditions of anonymity, and in multiple cartel-related cases, witnesses have been killed after their identities became known.
Human rights organizations operate under the same constraints. The documentary record reflects not simply what happened, but who survived, who was willing to speak, and whose account could be corroborated sufficiently to appear in a federal filing. The indictment is, in legal terms, a formal accusation and not a finding of guilt. Every individual named faces a legal presumption of innocence.
But the allegations assembled across years of investigative work and connected to specific victims whose names federal prosecutors placed in an indictment deserve serious examination. The victims at the center of these allegations were real people whose families have lived with incomplete information about what happened to them and why. The violence documented did not end when it happened to its immediate victims; its effects continued in communities that modified their behavior, in families left without answers, and in witnesses who cannot safely share what they saw.
According to federal prosecutors, the organization’s durability was built in significant part on a system of violence that made defection feel fatal, resistance feel futile, and accountability feel impossible.
