Cartel Jalisco Nueva Generación, Mexico’s fastest-growing and most violent cartel, appears to be moving into Sinaloa cartel territory in Tijuana, just across the border from San Diego.

CJNG is reportedly teaming up with former members of the Arellano Félix Organization (AFO) and recruiting current members of the Sinaloa cartel in the city in order to take control of drug-trafficking routes to the US, according to a February 13 report by Sandra Dibble of The San Diego Union-Tribune.

“Nueva Generacion does not have a significant physical presence in [Baja California, where Tijuana is located], but has focused on forging alliances with members of the Tijuana underworld in a challenge to the Sinaloa cartel,” Daniel de la Rosa, the public safety secretary in Baja California, told Dibble.

Bodies found in the city recently have borne narcomensajes, messages from the person’s killer, so named because they usually indicate a drug-related killing.

“The cleaning continues in Baja [California] on the part of El Mencho. Sincerely, CJNG CTNG,” read one message, referring to both CJNG and its local affiliate, Cartel Tijuana Nueva Generacion.

“El Mencho” is believed to be CJNG’s current leader, Nemesio Osegura Ramos.

Another group that has left messages on dead bodies, known as La Barredora, is purportedly made up of state and local police officers working on behalf of the Sinaloa cartel.

Rising homicides

This spike in homicides comes amid a longer-term increase in killings in the border city.

Tijuana is just across the border from San Diego, and the two cities' border crossings are heavily trafficked.

Tijuana’s homicide rate has jumped from 28 per 100,000 residents in 2012 to 39 per 100,000 in 2015, which made it the 35th-most-violent city in the world that year, according to a Mexican think tank.

Drug-related homicides were more than 536 of the city’s 670 homicides last year. Moreover, Dibble reports, 71 homicides in January were the most the city has seen in the first month of the year since 2010.

State officials are confident that the rise in killings (which has occurred alongside a drop in other common crimes) is the result of organized criminal activity — and of CJNG’s ambitions.

Violence has gone "up because a third group" that had not previously been in the city "is in the process of becoming established," the state’s deputy attorney general for organized crime, José María Gonzalez, told Dibble.
