Mors immigrated to New York City from his native Austria-Hungary in June 1914. The German-speaking Mors gained employment as a porter for the German Odd Fellows' Home in Unionport, New York through the Immigrant Free Employment Bureau. The home housed 250 orphans and 100 elderly men and women. Inexplicably, though he terrified the older residents, both the younger residents and visitors seemed to like him and enjoy his company. Mors exhibited signs of megalomania soon after beginning to work at the nursing home: he would wear a white lab coat with a stethoscope around his neck, and insisted that the elderly residents address him as "Herr Doktor."
Murders
In the four-month period from September 1914 to January 1915, 17 residents—an unusually high number—died at the Home. Fearing foul play, the administration called the police in to investigate. Mors had used arsenic and chloroform to murder at least eight of the elderly residents. He later claimed he was "putting them out of their misery". He committed his first murder using arsenic, purchased from a local druggist. Encountering some difficulties with this method, he later switched to the use of chloroform.
Investigation
Early in the investigation, police learned of the fear the elderly patients and staff had of Mors. On these grounds he soon became the primary suspect of the investigation. When questioned, Mors readily and calmly admitted to killing eight of the seventeen patients who had recently died. He claimed that these were mercy killings and that they had been nuisances. In detail, he described his method as:
First I would pour a drop or two of chloroform on a piece of absorbent cotton and hold it to the nostrils of the old person. Soon my man would swoon. Then I would close the orifices of the body with cotton, stuffing it in the ears, nostrils and so on. Next I would pour a little chloroform down the throat and prevent the fumes escaping the same way.
Mors also claimed that the home's superintendent had encouraged him to kill the more ill and more elderly patients. The district attorney declined to prosecute Mors, finding him to be criminally insane, and committed him to the Hudson River State Hospital, pending deportation to Austria. Mors escaped from the institution in May 1916. His later fate is unknown.
