In October of 2014, Italian authorities arrested a woman for the murder of as many as 38 victims. Most shocking was the revelation that she was the victims’ nurse. Police first charged the woman with the murder of a 78-year-old hospital patient. Later, however, they suspected her involvement in a string of suspicious deaths. News outlets posted a disturbing pic seized by police: a selfie the nurse took of herself (in her hospital scrubs) standing near the body of a recently deceased patient while smiling and making a thumbs-up gesture.
