93. In that same statement, Agent Sotomayor indicated that, at 10:00 p.m. that same day, December 30, 2009, three persons dressed in civilian clothes appeared at the facilities of the agency of the Public Federal Ministry, bearing AR15 arms, who did not identify themselves, except one of them, who said he was Commander Meza and who requested Agent Sotomayor to lend him the detained persons José Ángel Alvarado Herrera, Nitza Paola Alvarado Espinoza, and Rocío Irene Alvarado Reyes whom he held in his custody, to which he replied that he did not have any detained persons or persons remanded into his custody as a result of which he could not help them, in response to which he asked if he could talk to the military garrison to ask the soldiers when they were going to remand them, indicating that he could do nothing until they were remanded into his custody.84 94. Also matching what had been stated by Damaris Baglietto Hernández and Ramón Iván Sotomayor Siller, Argene Blázquez Morales indicated that she had received a phone call from someone who identified himself as a Federal Police Force Commander, who told her that he was aware of the detention of three persons by the Federal Police Force and that the detained persons were connected with the disappearance of agents of his institution, and she indicated that he should go to the Public Ministry and speak to the Deputy Delegate of said area. He specified that he had called Damaris Bagliette by cell phone or radio and he told her that she was on vacation, and that is why did not want to bother her with something so trivial, which was why he contacted the Public Ministry of Nuevo Casas Grandes and told her the content of the call, but he did not indicate how they were supposed to act.85 95. From the time of disappearance up to the day of that the present report was adopted, the whereabouts of Nitza Paola Alvarado Espinoza, Rocío Irene Alvarado Reyes, and José Ángel Alvarado Herrera are unknown. The only information in the case file is connected with the alleged phone call made by Nitza Paola Alvarado Espinoza on February 3, 2010. 96. Regarding this, on February 12, 2010, María de Jesús Alvarado stated that “[...] on the third of February of the present year, the house of Mrs. Ramona, who lives in Benito Juárez, received a phone call, the call was made at five thirty in the afternoon to phone number 636-69-80-101 which was received and answered by Juana Bustamante, who when she answered heard the voice a female person who identified herself as Nitza Paola Alvarado Espinoza, my sister told her to get her out of there, I don't know where I am, Juanita also remarked that she heard another voice, that of a male persons with a Chilango tone who said: "Dammit the bitch has already spoken" and at that moment they hung up.”86 97. As will be described in the following section, in the framework of the internal investigations, there is no information indicating that the authorities carried out a diligent and timely investigation on this call, and therefore the call did not shed any light on the whereabouts of neither Nitza Paola Alvarado Espinoza nor José Ángel Alvarado Herrera and Rocío Irene Alvarado Reyes. 84 Annex I.
