At the time of his arrest, Ramírez Olvera was reportedly not shown any official documentation indicating that the Mexican police had the legal authority to arrest him; the CNDH suspects that Reynosa customs agents may have been involved in the scheme as well, and that Rodríguez Mata and Cárdenas Gutiérrez were likely paid by the FBI agents to capture and illegally transport Ramírez Olvera to the U.S. without proper legal authorization.
