Prosecutors in Uruguay have filed murder charges against two nurses for at least 16 mercy killings, and jailed the suspects, the judge in charge of the case said. The male nurses, 39 and 46, were charged with homicides of patients both at a private Neurological Intensive Care Center and a public hospital’s intermediate-level care unit. A girlfriend of one of the men was charged with covering up information related to the case. Judge Rolando Vomero, in charge of the investigation, has not said exactly how many deaths are being probed. But he said that one of the suspects has admitted to 11 killings and the other to five. According to the judge, the accused used various methods to administer euthanasia. “In one of the cases,” he explained,” the suspect introduced morphine directly into the blood stream while in another, they pumped air into the blood stream, which resulted in deaths in just a few minutes.” The suspects have admitted they had been driven by a desire “not to see human suffering.” But they also acknowledged that their patients had not been afflicted by terminal diseases, Vomero pointed out. Uruguayan Interior Minister Eduardo Bonomi told a news conference that an investigation into the alleged killings had been launched in January following a criminal complaint that came from one of the medical facilities. “A death that occurred soon after gave investigators specific evidence,” Bonomy added, pointing out that he could not rule out that more people could have been involved in the killings. Defense attorney Ines Mazziotti said these were “mercy” killings. “After 20 years in intensive care, or constant stress on the edge of life and death, he could not take it anymore,” she said of one of the suspects, who were not immediately identified.
