Authorities are searching for a convicted drug lord who was released from prison after killing a DEA agent following a recent decision by a Mexican court, the Associated Press reports.
The Mexican Supreme Court pressured a lower court to reverse the decision to release Rafael Caro Quintero in August 2013 after serving just 28 years in prison.
Quintero has been missing since.
The U.S. expressed outrage after Quintero, who was convicted in the 1985 kidnapping, torture and murder of DEA Agent Enrique “Kiki” Camarena, was released early.
Quintero is considered the grandfather of Mexican drug trafficking.
