Charles Cullen

Charles Edmund Cullen (born February 22, 1960) is an American serial killer. Cullen, a nurse, murdered dozens—possibly hundreds—of patients during a 16-year career spanning several New Jersey and Pennsylvania medical centers until being arrested in 2003. He confessed to committing as many as 40 murders at least 29 of which have been confirmed; though interviews with police, psychiatrists and journalists suggest he committed many more. Researchers who are intimately involved in the case believe Cullen may have murdered as many as 400 people. However, most murders cannot be confirmed due to lack of records. Provided by Wikipedia
