"Stephan Letter (born 17 September 1978 in Herdecke, North Rhine-Westphalia) is a German former nurse and serial killer known to be responsible for the killings of at least 29 patients while he worked at a hospital in Sonthofen, Bavaria between January 2003 and July 2004. The acts have been described as Germany's largest number of killings since World War II...
...Stephan Letter was a nurse at a hospital that treated a large elderly population.During his employment from January 2003 to July 2004, a pattern of more than 80 deaths occurred on his shifts. Officials exhumed the bodies of more than 40 patients, but another 38 had already been cremated. Lesser became a suspect after officials learned that large quantitites of drugs, including the muscle relaxant lysthenon, had gone missing from the hospital.
...He confessed to some of the killings, but insisted that he acted out of sympathy and a desire to end the suffering of sick patients. However, the prosecution indicated that Letter was not the assigned nurse for some of the patients and that some of the patients were in stable condition and due to be released from the hospital."
