Enrique "Kiki" Camarena Salazar (July 26, 1947 – February 9, 1985) was an American intelligence officer for the United States Drug Enforcement Administration (DEA). In February 1985 Camarena was kidnapped by drug traffickers in Guadalajara, Mexico. He was interrogated under torture and murdered. Three leaders of the Guadalajara drug cartel were eventually convicted in Mexico for Camarena's murder. The U.S. investigation into Camarena's murder led to three more trials in Los Angeles for other Mexican nationals involved in the crime. The case continues to trouble U.S.–Mexican relations, most recently when one of the three convicted traffickers, Rafael Caro Quintero, was released from Mexican prison in 2013.
