A US jury found the former face of Mexico's war on drugs guilty of drug trafficking.
Former Mexican Security Minister Genaro Garcia Luna was convicted of stealing millions of dollars from the Sinaloa drug cartel, the country's largest organized crime organization.
Garcia Luna had entered a not-guilty plea after being detained in the state of Texas in 2019.
Up to 10 years in prison are possible for the 54-year-old.
After a four-week trial and three days of jury deliberation in the US District Court in Brooklyn, New York, the verdict was rendered.
The former director of the Mexican equivalent of the US Federal Bureau of Investigations allegedly accepted millions of dollars delivered by cartel members in briefcases.
He is the most senior Mexican official to have ever been tried in the US.
From 2006 to 2012, Garcia Luna oversaw public security during the rule of President Felipe Calderon. He had previously served as the Federal Investigation Agency's director from 2001 to 2006.
