Sons of former Sinaloa cartel leader Joaquín “El Chapo” Guzmán have denied accusations made by U.S. prosecutors last month, saying in a letter that they have no involvement in the production and trafficking of the potent synthetic opioid fentanyl.
The letter was provided to The Associated Press by José Refugio Rodríguez, a lawyer for the Guzmán family. Despite not being signed, Rodríguez said he could confirm that the letter was from Guzmán’s sons.
