41 year old Niels Hoegel, who was convicted and sentenced to life for two murders in 2015 has now been blamed for the deaths of at least 100 according to investigators. Hoegel used lethal drugs to kill the patients “out of boredom” and to impress his colleagues. He wanted to be seen as the “hero” who resuscitated patients, but many of the patients he distressed had died. Investigators confirmed that Hoegel has killed 16, and expect higher numbers after further investigation. If he is found guilty of all of the murders, Hoegel will be one of Germany’s worst post-war serial killers.
