Crimes
During the summer and autumn of 1981, a series of suspicious deaths were uncovered at the Orkdal nursing home that Nesset managed. When questioned by police, Nesset initially confessed to the murders of 27 patients, whom he claimed to have killed by injecting them with suxamethonium chloride, a drug to paralyze muscles. He was charged with 25 counts of homicide but later retracted his confession and denied all charges for the rest of his five-month trial.
