Later on during a press conference in Acapulco, he added that it was the "Director of Public Security of Iguala Francisco Salgado Valladares who gave the order to detain the student teachers from Ayotzinapa; and an individual known as 'El Chuky' from the criminal group Guerreros Unidos would have ordered the kidnap and murder of the young students."
