79 provided by competent professionals who are trustworthy for the victims, including the provision of medications as well as costs of transportation and interpreters, as required. 250. During the public hearing, the State indicated that it would consider “the provision of specialized health services for the victim and [her] children.” Nevertheless, in its final written arguments, the State did not offer more specificity in this regard. 251. The Court finds, as it has in other cases,254 that a measure of reparation must be ordered that provides appropriate care for the physical and psychological effects suffered by the victims, which attend to their gender and ethnicity. Consequently, having verified the violations and the harm suffered by the victims in the present case, the Court decides that the State is obliged to provide them, free of charge and immediately, with the medical and psychological care they require. Prior, clear, and sufficient information should be offered to the victims so as to obtain their consent. The treatments should be provided for the time that is necessary, and should include the provision of medication, and where applicable, transportation, interpreters, and other costs that are directly related and strictly necessary. 252. In particular, the psychological or psychiatric treatment must be provided by State personnel and institutions specialized in attending to victims of acts of violence such as those that occurred in this case. If the State does not have this type of service available, it must have recourse to specialized private or civil society institutions. When providing this treatment, the specific circumstances and needs of each victim must be considered, so that they are offered individual and family treatment, as agreed upon by each of them, and following an individual evaluation.255 Lastly, this treatment must be provided, insofar as possible, in the institutions nearest to their place of residence. In the same way, those who requested this measure of reparation, or their legal representatives, have six months as of the notification of this Judgment to inform the State of their specific requests for psychological or psychiatric treatment. The Court highlights the need for the State and the representatives to offer their best collaborative efforts and to provide the victims with all the information necessary for said victims to receive the psychological treatment in order to advance the implementation of this measure in an agreed upon manner. vi) Protocol for the diligent investigation of acts of violence 253. The Commission asked the Court to order the State to design protocols to facilitate and promote the effective, standardized, and transparent investigation of acts of physical, sexual, and psychological violence. They should include a description of the complex nature of the evidence, and details of the minimum evidence that must be collected in order to provide adequate probative grounds, according to the provisions of the Istanbul Protocol. 254. The State reported on the adoption of distinct protocols related to the investigation of violence against women in the state of Guerrero such as the protocols of care to women in situations of violence and of the investigation of crimes of homicide with a focus on feminicides. Moreover, it reported on the 254 Cf.
