full_context: Document 1: Charles Cullen: Charles Edmund Cullen (born February 22, 1960) is a former nurse who is the most prolific serial killer in New Jersey history and is suspected to be the most prolific serial killer in American history. He confessed to authorities that he killed up to 40 patients during the course of his 16-year nursing career.

Experts have estimated that Charles Cullen may ultimately be responsible for 400 deaths, which would make him the most prolific serial killer in American history.

The trial was featured in headlines around the world and was described at the time as "one of the greatest murder trials of all time" and "murder trial of the century". It was also described at the time as "unique" because, in the words of the judge, "the act of murder" had "to be proved by expert evidence."
