17 She added that subsequently the National Police Force arrived to collect the body of Anstraum Aman Villagrán Morales and they asked her if she knew or had seen anything; however, she refused to answer because she was afraid. Several days after the death of Villagrán Morales, the man who had accompanied him on the night he was murdered came to the kiosk again. He arrived in the uniform of the Fifth National Police Corps, in a blue pick-up truck, identified as belonging to the same police corps, and accompanied by other policemen, who were conducting a “raid”. This man was looking for her mother who also worked in the kiosk. She told her mother that police agents were looking for her. It was then that her mother, who feared for her own life, advised her to make a statement about what she had seen. She said that she went to make a statement to the National Police Force and then her mother went to the United States “for fear that something [might happen to her]”. She stated that she also made a statement before the “courts” and that the State did not take any measure to protect her safety or that of her mother. On March 26, 1991, she made a statement before a judge. On October 9, 1990, she had done the same to National Police Force investigators. She identified a policeman named Néstor Fonseca López as a participant in the murder, from a “kardex”, that is cards with identification photographs. With regard to the personal identification procedure, she stated that “[she] was taken to several places, but [Néstor Fonseca López] was not there” and she was never called to personally identify Samuel Rocael Valdez Zúñiga.

It was his responsibility to “collect the physical evidence and interview the persons who were present”. He was in charge of the preliminary investigation in the case of Anstraum Aman Villagrán Morales. He arrived at the scene of the crime in civilian clothes at approximately one in the morning. There, he found a “Police Force vehicle […], the Identification Section vehicle [both of the national Police Force] and a vehicle with the judge”. He stated that he was able to observe when a person from the Identification Section of the National Police Force found a bullet head “of unknown caliber” about a meter from the body. He did not have access to the results of the ballistic tests because it was not part of his work, but according to the characteristics of the hole where the bullet entered, he calculated that it could have been a .30 or .38 caliber.
