Sigifredo Nájera Talamantes

Sigifredo Nájera Talamantes (died 7 September 2015), commonly referred to by his alias El Canicón, was a Mexican drug lord and high-ranking leader of Los Zetas.

Kingpin Act sanction
On 24 March 2010, the United States Department of the Treasury sanctioned Nájera Talamantes under the Foreign Narcotics Kingpin Designation Act (sometimes referred to simply as the "Kingpin Act"), for his involvement in drug trafficking along with fifty-three other international criminals and ten foreign entities. The act prohibited U.S. citizens and companies from doing any kind of business activity with him, and virtually froze all his assets in the U.S.

Arrest
He was captured on 23 March 2009. The government of Mexico had listed Nájera Talamantes as one of its 37 most-wanted drug lords and offered the equivalent of over $1 million USD for information leading to his capture.

Death
He died of a heart attack inside his prison cell at the Federal Social Readaptation Center No. 1 on 8 September 2015.
