Just a day after Joaquín Guzmán Loera, the drug kingpin known as El Chapo, was convicted of all 10 counts in a drug conspiracy case in Brooklyn, the Department of Justice unsealed another indictment — against two of his younger sons.

That brief four-page indictment, announced by the department on Thursday more than a week after it was unsealed on Feb. 13, charges Joaquín Guzmán López and Ovidio Guzmán López with one count of conspiracy to “knowingly, intentionally, and willfully” distribute cocaine, methamphetamine and marijuana for importation into the United States. The indictment entails a period from April 2008 — when their father was running the Sinaloa cartel with his partner, Ismael Zambada — to April 2018.

The two brothers have yet to be arrested and authorities believe that they are in Mexico. If they are arrested there, the United States would have to extradite them to bring them to trial, which would be held under Judge Rudolph Contreras of the United States District Court for the District of Columbia.

A. Eduardo Balarezo, one of El Chapo’s lawyers, questioned the timing of the indictment. “The recent indictment against Joaquín’s two sons smacks of a concerted attempt by the government to paint the entire family as being involved in criminal activity when the only evidence they have of it is based on cooperator testimony,” he said.
