This man was born in West Orange, New Jersey to a working-class Irish Catholic family, the last of eight children. Did he turn out to be a scientist or a serial killer?

The man in this photo is Charles Edmund Cullen, a convicted serial killer and former nurse who confessed to murdering up to 40 patients. Sadly, the number of victims could be up to 400, which would make him the most prolific serial killer in recorded history.
