NEW YORK (Reuters) - Sons of accused Mexican drug lord Joaquin "El Chapo" Guzman murdered a journalist well known for his coverage of drug cartels, a former associate testified at Guzman's U.S. trial on Wednesday.

Damaso Lopez Nunez, a former top lieutenant to Guzman, made the accusation in Brooklyn federal court under cross examination by one of Guzman's lawyers. The lawyer, Eduardo Balarezo, had asked Lopez whether his own son, Damaso Lopez Serrano, might have been involved in the May 2017 murder of Javier Valdez.
