Investigation into threats, forced displacement, and destruction of residence of Miryam Eugenia Rúa Figueroa and her next of kin 355. According to information produced by the State, the 18th Special Prosecutor, under the Human Rights Unit of the Office of the Attorney General, is pursuing as file No. 4016 an investigation into the alleged crime of forced displacement of which Ms. Rúa was a victim.517 That investigation, in the preliminary stage, is under seal, and no one has been identified as one of the persons responsible for that conduct.518 When Ms. Rúa reported the facts to the authorities on July 8, 2002, she noted as the persons responsible the autodefensas operating in her neighborhood.519 The IACHR has no information indicating that investigations have been carried out by the disciplinary jurisdiction; or that any measures have been taken to remedy the context of insecurity that makes it impossible for Ms. Rúa to return to Comuna 13. 356. In view of the foregoing, the Commission notes that with more than ten years having elapsed since the incidents that are the subject of this claim took place, the threats and forced displacement of Mrs. Rua and her family members have remained in impunity. Pursuant to the abovecited international standards, the IACHR reiterates that as a general rule an investigation must be conducted promptly and without delay in order to protect the interests of the victims, preserve the evidence, and even safeguard the rights of everyone who, in the context of the investigation, may be considered a suspect. Both the Inter-American Commission and the United Nations High Commissioner for Human Rights have consistently issued statements on the high level of impunity in human rights violations committed by members of the public security forces and paramilitary groups in Colombia, and the significant number of criminal proceedings and of open disciplinary investigations against these officers, which do not result in establishing guilt, much less the appropriate punishment of those responsible.520 357. By virtue of these considerations, the Commission finds that the State failed in its duty to act with due diligence to investigate and punish promptly and adequately those responsible for the facts pertaining to the threats, forced displacement, and occupation and destruction of the property of Ms. Rúa, in breach of Articles 8.1 and 25 of the same instrument, in connection with Article 1.1 thereof, and Article 7 of the Convention of Belém do Pará. It further finds that the State violated Articles 8.1 and 25 of the American Convention, in connection with Article 1.1, to the detriment of the next of kin of Ms. Rúa, identified as Gustavo de Jesús Tobón (permanent companion), Bárbara del Sol (daughter), Úrsula Manuela (daughter) and Valentina (daughter). 4.
