Authorities detailed that police, prosecutors and forensic examiners in northern Mexico seemingly conspired to cover up the killing of Héctor Cuén, a Sinaloa politician and opponent of Gov. Rubén Rocha Moya.
Days after his arrest, Zambada claimed in a hand-written letter that he was forced aboard an airplane on July 25 by Joaquín Guzmán López and his gunmen, who then flew them both to the United States where they were turned in to authorities. In the letter, Zambada also made mention of the murder of Cuén, who died on the same day, at the same time, and at the same ranch were Zambada claimed to be kidnapped.
