Career
Williams, who worked as an artificial flower-maker, claimed to have witness-confirmed alibis for the major Monster attacks, but he was firmly identified by several victims (although not all of them) as the attacker. His main alibi was heavily questioned in court, although some have nevertheless viewed it as a fairly good alibi. Amidst an atmosphere of great public hostility towards Williams, he was ultimately convicted and sentenced to six years in prison.
He was released in December 1796.
Mass hysteria appears to have played a considerable role in the events surrounding the London Monster, and it is uncertain to what extent, if any, Rhynwick Williams was responsible for the various attacks.
