12 Bone-Chilling Serial Killer Documentaries on Netflix Now

This hour-and-a-half-long documentary recounts how police proved a New Jersey ICU nurse, Charles Cullen murdered his patients. While investigators believe Cullen may have killed up to 400 patients over the course of his killing spree throughout the 2000s, he was only ever convicted for 29 murders because of his very under-the-radar method of killing: administering standard drugs like digoxin, insulin, and epinephrine to make his patients overdose. "Capturing the Killer Nurse" breaks down the events that led to Cullen's eventual capture after 16 years of undetected killing.

If this story sounds familiar, it's probably because Netflix produced a dramatization of Cullen's murders called "The Good Nurse," starring Eddie Redmayne and Jessica Chastain.
