Ernesto Fonseca Carrillo

Ernesto Fonseca Carrillo (born August 1, 1942) also known by his alias Don Neto, is a former Mexican narcotics trafficker, and leader of the Guadalajara Cartel alongside Miguel Ángel Félix Gallardo and Rafael Caro Quintero. Fonseca had been involved with smuggling since the early 1970s, primarily in Ecuador, later moving his operations to Mexico.

Fonseca is the uncle of former Juarez Cartel leader, Amado Carrillo Fuentes.

The United States Drug Enforcement Administration (DEA) in 1982 indicted Fonseca in a money laundering operation in San Diego. Prior to the DEA receiving permission to wiretap the phones where Fonseca was thought to be hiding, Fonseca fled back to Mexico. On April 7, 1985, Fonseca was located in Puerto Vallarta by the Mexican Army, his villa was surrounded and he eventually surrendered.

Fonseca was later linked to, and admitted taking part in the 1985 murder of DEA agent Enrique Camarena, who was kidnapped and tortured by the Guadalajara cartel. Fonseca did not admit to killing Camarena and stated he was outraged that the agent was beaten. Fonseca would eventually be found guilty of the murder by the Mexico judicial system. He was ultimately convicted and sentenced to 40 years in prison. However, Fonseca was never extradited to the United States to stand trial.

Fonseca was transferred from prison to house arrest in July 2016 because of his health. As of July 2016, he is aged 73 and has nine more years to serve of his 40-year sentence.
