Mexican authorities have found 20 bodies in Sinaloa, including four decapitated victims hanging from a bridge near Culiacán and 16 more bodies inside a van parked underneath it, in the latest sign of the state’s deepening cartel war.
The Guardian reported that the state prosecutor’s office confirmed the grisly discovery on Monday. One of the 16 victims found in the van had also been decapitated, and the severed heads were found in a bag at the site. That level of brutality makes the incident stand out even in a conflict already marked by extreme violence.
The bodies were found in a region where the war between factions of the Sinaloa cartel has been intensifying since September 2024. The split, described by The Guardian, pits a faction led by El Mayo’s son against the group led by El Chapo’s sons. The report says the conflict began after the arrest in Texas of two major cartel figures and has since left nearly 3,000 people dead or missing.
A message found alongside the bodies indicated the perpetrators belonged to La Mayiza, the faction linked to El Mayo’s son. That detail matters because it suggests the killings were not random but part of a communication war as well as a shooting war. In cartel conflicts, the scene itself often doubles as a threat and a claim of territory.
The report also notes growing evidence that the Jalisco New Generation cartel may have joined the fight on the side of Los Chapitos, potentially broadening the conflict and changing the balance of power. The United States Drug Enforcement Administration has warned about that possible alliance.
The Mexican government has sent thousands of soldiers to Sinaloa, but the violence has continued. The Guardian described the last two months as the most violent so far and said the war has reached a level that even heavy security deployments have not contained. That is the deeper significance of the Culiacán discovery: it shows the state has not regained control despite a military presence.
The attack also sits inside a wider fentanyl and trafficking struggle. US authorities have identified the Chapitos as key drivers of fentanyl trafficking, and the Trump administration has increased pressure on Mexico to act. But the bodies in Sinaloa show that the conflict is still driven as much by internal cartel rivalry as by outside pressure.
For residents near Culiacán, the immediate reality is the image of a bridge turned into a killing site. For the authorities, the challenge is that each gruesome killing appears to be followed by another. The discovery of 20 bodies is therefore not only a crime scene; it is a snapshot of a war that has now become one of the deadliest organised-crime conflicts in Mexico.
