Heather Pressdee, 41, was already facing charges after Pennsylvania’s Attorney General Michelle Henry said the registered nurse from Natrona Heights confessed to intentionally administering a lethal dose of medication to three patients at the Quality Life Services nursing facility in Chicora, a borough in western Pennsylvania. She was charged in May with homicide and attempted murder after two men, ages 55 and 83, died and a third was hospitalized, Henry said in a news release.
