Serial Killer Autopsy: Charles Cullen, America's Deadliest NurseThe Most Prolific Serial Killer in American History Wore Scrubs and Worked the Night ShiftBetween 1987 and 2003, registered nurse Charles Cullen moved quietly through hospitals and nursing homes across New Jersey and Pennsylvania, murdering patients with lethal injections of medications like digoxin, insulin, and epinephrine. While officially convicted of killing 29 patients, forensic experts estimate he may have murdered as many as 400, making him potentially the most prolific serial killer in recorded history.But Charles Cullen's sixteen-year killing spree raises questions far more disturbing than the psychology of one damaged man: How did he get away with it for so long? Why did seven different healthcare facilities allow him to resign quietly when suspicions arose, rather than reporting him to authorities? What systemic failures enabled him to move from hospital to hospital, leaving a trail of bodies at each, while background checks and regulatory systems failed to detect the danger?This book goes beyond true crime sensationalism to explore profound questions about trust, vulnerability, and institutional accountability. It examines the "Angel of Death" phenomenon, healthcare workers who kill their patients through historical comparison with other cases worldwide. It evaluates the legal and medical reforms enacted after Cullen's conviction, asking whether patients are truly safer today or whether another predator could still exploit the same vulnerabilities.Drawing on court documents, psychiatric evaluations, investigative records, victim impact statements, and interviews with those who knew Charles, Serial Killer Autopsy: Charles Cullen presents a complete portrait of a killer who looked like anyone, who seemed like an ordinary colleague, and who exploited the most fundamental trust in society, the trust we place in those who care for us when we are most vulnerable.Charles Cullen's crimes demand examination not just for their horror but for what they reveal about the systems meant to protect us. When those systems fail, when hospitals pass dangerous employees from one facility to another, when regulatory agencies move too slowly to stop harm, when professional courtesy protects killers more than patients, the result is body counts that approach the scale of mass disasters.This is not just the story of one killer. It is an autopsy of the institutional, regulatory, and cultural failures that enabled one of America's worst serial murderers to operate for sixteen years while countless opportunities to stop him were squandered.For readers of true crime, medical thrillers, and institutional accountability, a chilling examination of how evil hides behind ordinary faces and how systems designed to protect us can fail so completely that monsters work among us, unseen and unstopped, for years.
