12 the application (supra, paras. 49 and 56) and already formed part of the probative material in this case, so that a second incorporation would be redundant. B) TESTIMONIAL EVIDENCE 65. During the public hearing, the Court received the following testimonies: a. Testimony of Ana María Contreras, mother of Henry Giovanni Contreras She declared that, during 1989 and 1990, her son sometimes lived on the streets of Guatemala City, specifically on 18th, 9th and 17th streets. In June 1990, when he was abducted, he was spending some periods of time with her in her house and others in Casa Alianza. Moreover, during this time her son worked in a printing workshop. On June 15, 1990, between nine and ten in the morning, Henry Giovanni Contreras left his home to obtain an identity card as he had recently had his 18th birthday. When about 15 days had elapsed and he had not returned, the witness went to look for him “on the streets”. She asked in a café located in front of a place called “the Zocalo”, on 18th Street, showing a photograph of her son. The woman who worked in the café told her that “he had been taken away in a pickup truck with some other boys”. The following day, she went to the Guatemalan National Police Force (hereinafter “National Police Force”) where the death of Henry Giovanni Contreras was confirmed and she was shown a half-length photograph of “the body [of her son] with a bullet wound”. Furthermore, she was told that she should go to Mixco, where she could find out more details of what had happened. In Mixco, they explained to her that Henry Giovanni Contreras had been found dead in the San Nicolás Woods and she was questioned about this. She declared that she was also summoned by a court or tribunal, which she only referred to as a “court”, where “they questioned” her about her son, although she does not remember the exact nature of the questions. She stated that she could not bury her son, because numerous bureaucratic measures were required in order to obtain his body and she “was already suffering from health problems in her head that later began to get worse”. She declared that, as a consequence of what happened to her son, she developed a facial paralysis that “resulted in a year in hospital”. She added that, following her statements to the courts, she received an anonymous threatening letter. This frightened her and she said that she was also afraid to be making a statement on the events to the Inter-American Court. She indicated that she did not know who was responsible for the death of her son or what were the motives for his assassination. She only learned though the media that the alleged perpetrators had been arrested and then freed. She has not been summoned again to make statements to the courts.
