MEXICO CITY – Defense attorneys believe freedom is imminent for a second member of the trio of Mexican drug kingpins responsible for the 1985 slaying of a Drug Enforcement Administration agent, one of the capo’s attorneys said Saturday. In the U.S., outrage grew over this week’s surprise decision to overturn Mexican drug lord Rafael Caro Quintero’s conviction in the notorious killing.

Caro Quintero walked free Friday after a federal court overturned his 40-year sentence in agent Enrique “Kiki” Camarena’s kidnapping, torture and murder. The three-judge appeals court in the western state of Jalisco ordered Caro Quintero’s immediate release on procedural grounds after 28 years behind bars, saying he should have originally been prosecuted in state instead of federal court.

Also imprisoned in the Camarena case are Ernesto Fonseca Carrillo and Miguel Angel Felix Gallardo, two of the founding fathers of modern Mexican drug trafficking, whose cartel based in the northwestern state of Sinaloa later split into some of Mexico’s largest drug organizations.

Fonseca Carrillo’s attorney, Jose Luis Guizar, said his team had filed an appeal based on the same procedural grounds used by Caro Quintero, and expected him to be freed within 15 days by a different court in Jalisco.

“The appeal is about to be resolved. We believe that the judges will stick to the law,” Guizar said. “Fonseca Carrillo should already be on the street. He should be at home. At its base, the issue is the same as Rafael’s. “

He said he had not spoken to Felix Gallardo’s attorneys about their expectations for that case.

The U.S. Department of Justice said Friday that it found the decision to free Caro Quintero “deeply troubling.”
