Over the past dozen years, organized crime groups such as the Sinaloa Cartel and the Cartel Jalisco Nueva Generación have vied for control of Tijuana, making alliances with remaining factions of the once-dominant Arellano-Félix Cartel, and then fragmenting, re-forming and battling each other, according to police and criminal justice experts.
ituated on the border with the United States, Tijuana has always been a prize for smugglers. But in the past decade or so, a new market has emerged.
In distressed neighborhoods like Sánchez Taboada, drug dealers can make a fortune selling crystal meth on street corners, out of mom-and-pop convenience stores, and the parking lots behind local bars, he said.
The violence got worse in the power vacuum left after Sinaloa crime boss Joaquin “El Chapo” Guzman was extradited to stand trial in the U.S. in January 2017, said Professor David Shirk, an expert on criminal justice in Mexico at the University of San Diego. The strategy of the Mexican and U.S. government to target the top leaders of criminal organizations has led to a breakdown in cartel hierarchy and discipline, he said.
