The Lorenzanas are one of Guatemala's most long running drug trafficking groups, who have a relationship with Mexico's Sinaloa Cartel that stretches back at least two decades. Their reach once extended from Guatemala's poorest communities, whose support was bought with largesse, to the upper echelons of the country's political elite. However, in recent years they have become debilitated and their influence has declined.
Waldemar Lorenzana was arrested in December 2008 for alleged weapons possession but was soon released for reasons that illustrated their reach into the government justice system. In April 2010, the U.S. Treasury froze the assets of Waldemar and his three sons, citing connections with the Sinaloa cartel. Then, after a change of government in 2011, their empire came crashing down and Lorenzana and his sons, Eliu and Waldemar, were all arrested. After a lengthy legal process, Lorenzana was extradited to the United States in March 2014. His sons remain in prison in Guatemala and are themselves fighting extradition.
