Angel of Death

For 15 years, Charles Cullen slipped fatal doses of drugs into his patients' IVs — earning him the nickname the "Angel of Death." Throughout his 16-year medical career, Charles Cullen bounced back and forth between various hospitals and nursing homes throughout New Jersey and Pennsylvania. However, the nurse’s frequent relocation was not born out of a desire to help as many people as possible. He was actually killing his patients and then fleeing before anyone caught on.
