MEXICO CITY (AP) — A new era is coming for Mexico’s powerful Sinaloa cartel in the wake of the capture by U.S. authorities of Ismael “El Mayo” Zambada, the last of the grand old Mexican drug traffickers.

Experts believe his arrest will usher in a new wave of violence in Mexico even as Zambada could potentially provide loads of information for U.S. prosecutors.

Zambada, who had eluded authorities for decades and had never set foot in prison, was known for being an astute operator, skilled at corrupting officials and having an ability to negotiate with everyone, including rivals.

Removing him from the criminal landscape could set off an internal war for control of the cartel that has a global reach — as has occurred with the arrest or killings of other kingpins — and open the door to the more violent inclinations of a younger generation of Sinaloa traffickers, experts say.

With that in mind, the Mexican government deployed 200 members of its special forces Friday to Culiacan, Sinaloa state’s capital.

There is “significant potential for high escalation of violence across Mexico,” said Vanda Felbab-Brown, a senior fellow in the Strobe Talbott Center for Security, Strategy and Technology at the Brookings Institution. That “is bad for Mexico, it’s bad for the United States, as well as the possibility that the even more vicious (Jalisco New Generation cartel) will rise to even greater importance.”
