Charlie Cullen

Charlie Cullen was a nurse who would randomly, sometimes intentionally, kill patients on his floor. Charlie had mental problems that stemmed from a difficult childhood filled with abuse. Charlie would often attempt suicide, though he always sought help in plenty of time.

Charlie used a combination of drugs to kill patients. Sometimes he would use high doses of insulin to make a patient have convulsions. Other times he would use digoxin to watch the patients go into cardiac arrest. Charlie also used a cocktail of drugs, sometimes injecting them randomly into IV bags. Charlie liked to watch on medical records how each patient responded to his random medications.

Charlie thought he was invincible because he was caught practically red-handed on several occasions, but no charges were ever filed. Charlie left a trail intentionally at some of the hospitals where he worked, but nothing came of it...
