Puerto Vallarta, Jalisco, Aug. 31, 2026 — Threatening banners and two bodies hanging from a Tepic bridge this month have raised concern over a possible territorial conflict in Nayarit.
The banners appeared Aug. 12 in San Cayetano and at the Los Lobos bridge. Two bodies were found at Los Lobos three days later, according to reporting from Tepic.
The messages were attributed to the Cártel Jalisco Nueva Generación, or CJNG, and a network associated with La Mayiza. Nayarit authorities have not authenticated the banners or confirmed an open conflict between the groups.
No direct incident reported in the Puerto Vallarta area
The documented incidents occurred in Tepic, not Puerto Vallarta or Bahía de Banderas.
Our review found no incident in Bucerías, Nuevo Nayarit, La Cruz de Huanacaxtle or other communities around the bay connected to the Tepic cases. The Nayarit government’s public response did not announce road closures or travel restrictions.
The local connection is geographic. Highway 200 connects Puerto Vallarta and Bahía de Banderas with Compostela and Tepic. Residents and businesses use that corridor for travel, freight and government services.
Neither banner location was along Highway 200 in Bahía de Banderas. One appeared near Federal Highway 15 in San Cayetano. The second was reported at Los Lobos, near the junction of the free road and the Tepic-Mazatlán toll highway.
The distinction is necessary because developments in Nayarit are sometimes reported as affecting the entire state, including Riviera Nayarit. The August cases described in the reviewed reports were concentrated around Tepic.
Bodies found after rival-attributed banners
The first banner appeared during the early hours of Aug. 12 near San Cayetano, according to contemporaneous reporting on the locations. It contained language associated with La Mayiza, a faction of the Sinaloa cartel.
Another banner appeared later at Los Lobos and carried the initials CJNG. Videos circulated online showing people placing the messages, but the identities of those people were not established.
On Aug. 15, authorities found two bodies hanging from the Los Lobos bridge. A separate message at the scene was directed at state officials, police sources said.
Security personnel closed the area while the state Medical Examiner’s Office removed the bodies. The closure caused traffic delays near the Tepic-Mazatlán interchange.
Public reporting reviewed by PVDN did not identify the victims. It also did not provide an official determination connecting their deaths to either organization named on the earlier banners.
Authorities reject unverified cartel claims
The Nayarit government said security agencies from all three levels of government responded to the banner reports. Officials also increased operations in parts of Tepic.
“Security institutions neither validate nor distribute messages attributed to criminal groups,” the government said in a Spanish-language public statement, translated by PVDN. “The institutional response is and will continue to be operational work, prevention and enforcement of the law.”
Gov. Miguel Ángel Navarro Quintero questioned whether the online images were authentic. He said authorities had no confirmation that another criminal organization had entered Nayarit to establish territorial control.
That official position differs from some national coverage describing the incidents as proof of a cartel war. The evidence confirms the banners, the bodies and the security response. It does not establish who ordered either action.
Analysts see wider instability in western Mexico
Francisco Jiménez Reynoso, an academic at the University of Guadalajara, said in an Aug. 31 regional assessment that a period of reduced conflict between criminal factions had ended.
He said leadership losses and federal operations could produce further violence between rival networks. Rubén Ortega Montes, another University of Guadalajara academic, described western Mexico as entering a period of uncertainty.
Those assessments concern the wider region. They do not document a new cartel confrontation in Puerto Vallarta.
The 2026 Mexico Peace Index identifies cartel fragmentation as a continuing security risk. Its analysis links recent changes to the division of the Sinaloa cartel between La Mayiza and Los Chapitos, along with shifting relationships involving CJNG.
Nayarit experienced an earlier security disruption following the April arrest of Audias Flores Silva, an alleged senior CJNG operator. Blockades and fires followed in several Nayarit municipalities, while PVDN’s reporting found that Puerto Vallarta remained calm.
The current U.S. State Department advisory places Nayarit at Level 2, advising increased caution because of crime and terrorism concerns. It lists no specific travel restrictions for U.S. government employees in Nayarit and no restrictions for Puerto Vallarta or neighboring Riviera Nayarit.
