Mexico has begun proceedings to extradite an alleged gang member accused of killing U.S. federal agent Jaime Zapata in February.
Julian Zapata Espinoza, alias "El Piolin," is wanted by the U.S. on charges of homicide, reports The Houston Chronicle.
The alleged Zetas gang member is a suspect in the killing of U.S. Immigration and Customs Enforcement agent Jaime Zapata on a Mexican highway. Another agent, Victor Avila, was also wounded in the attack.
Mexican authorities captured Zapata a week later in San Luis Potosi. He said he had shoot the agents after mistaking them for members of a rival criminal group.
The suspect has now entered an extradition process that officials said could take a long time to be completed.
