46 victim was in a situation of permanent overcrowding; he was in a reduced cell, inhabited by numerous inmates; he had to sleep on the floor for a long period of time; he did not receive an adequate diet or drinkable water, nor did he have essential hygiene conditions (supra para. 54(48)). 109. In the public hearing held on June 28, 2005 before the Court, the State not only acknowledged that Mr. Alfredo López Álvarez suffered “real hardships” during his detention, but it also stated that “the truth is that the conditions in the criminal centers of practically all the Republic are not the best.” 110. From that previously stated we can conclude that the alleged victim was not treated with the due respect to his human dignity, and that the State did not comply with the duties that correspond to it in its condition of guarantor of the rights of the detainees. d) Lack of separation between the accused and the convicted in the criminal centers 111. Article 5(4) of the American Convention states that “save in exceptional circumstances”, the accused persons must be segregated from convicted persons, and be subject to a treatment appropriate to their status.96 112. It has been proven that in the penitentiary centers where Mr. Alfredo López Álvarez was incarcerated there was no classification system for the detainees. For more than six years and four months during which he was deprived of his liberty, he remained in company of convicted inmates, without the State having invoked and proved the existence of exceptional circumstances (supra para. 54(47)). * * * 113. The previous consideration lead the Court to conclude that the State is responsible for the violation of the right to personal integrity, enshrined in Articles 5(1), 5(2), and 5(4) of the American Convention, with relation to Article 1(1) of said instrument, in detriment of Mr. Alfredo López Álvarez. * * * 114. The representatives argued the violation of Article 5(1) of the Convention due to the breach of the mental and moral integrity of the closest family members of Mr. Alfredo López Álvarez (supra para. 101(c)). 115. Although the Inter-American Commission did not argue said violation, the Court has established that the alleged victims, their next of kin, or their representatives may invoke rights different to those included in the Commission’s application, based on the facts presented by the latter (supra para. 82). 96 Cf.
