One of the most prolific serial killers in history, Charlie Cullen, killed an estimated 40 people in sixteen years while working as a nurse in seven different hospitals. He was tried, convicted and is currently in prison.
He broke a long-standing silence for an interview on CBS Sixty Minutes last night. To try to understand why he committed these crimes, the show featured, Charles Graeber, author of The Good Nurse: A True Story of Medicine, Madness, and Murder (Hachette/Twelve, $26.99, 9780446505291. 4/15/13). The chilling answer was, “Because he could.”
