Nesset is infamous for one of the worst criminal cases in Norwegian history. He was convicted against his will in 1983 of killing 22 patients at a nursing home in Orkdal, where he worked as a nurse.
According to the verdict, Nesset used a muscle relaxant to kill his victims. The murders took place over a four-year period.
A total of 60 suspicious deaths were investigated at the Orkdal nursing home. Nesset was released in 2004 and "passed away peacefully" in a nursing home on Tuesday, his lawyer told VG.
