Uruguayan police say an investigation into dozens of possibly induced deaths at two hospitals, including Asociacion Espanola, has led to the detention of at least two people. Police inspector Jose Luis Roldan said Sunday that officials suspect that hospital workers brought a sort of poison from Brazil and gave it to patients who were in critical condition.

The judge overseeing the case said there was no indication the two male nurses were acting together. 10 Most Depressing Careers 10 jobs that may hurt your heart Judge Rolando Vomero said after a court hearing that the accused admitted to causing a total of 16 deaths of patients, but added that the investigation continued and the number was not final. He said most of the apparent victims "were not terminally ill." He said they were injected with overdoses of morphine or aid to "cause death within minutes." Vomero said one male nurse who worked at both hospitals admitted being involved in five induced deaths, and the other to 11 deaths in one hospital. The judge said that from the evidence gathered so far, it "does not appear that there were any connections" between the two nurses "even though they both worked at the same place." Lawyer Ines Massioti, representing one of the nurses charged with "especially aggravated murder," told reporters that the judge had ruled the suspects could be held in jail while the investigation proceeds. Massioti said her client acted "out of pity." "After 20 years of working in intensive care, with stress and in contact with death, he could not stand it anymore," the lawyer said. Earlier in the day, police inspector Jose Luis Roldan said officials were investigating suspicions that some hospital workers had given poison to patients who were in critical condition at the two hospitals.
