The founder of the now-defunct Guadalajara Cartel, Rafael Caro Quintero, was arrested after years of being a fugitive of the law.
The infamous drug trafficker had two arrest warrants issued by the Attorney General's Office, as well as an extradition order to the United States.
His alleged violent crimes included kidnapping and felony murder of a federal agent, aiding and abetting, racketeering and more.
In 1985, the FBI alleged he helped interrogate, torture, and murder DEA special agent Enrique "Kiki" Camarena in Mexico.
