Toward the end of 1725, two men named Thomas Wood and Thomas Billings (the latter the couple's biological son, adopted out) lodged with the couple. Having been
promiscuous since her mid-teens, Hayes began conducting affairs with both men, and the trio soon decided to kill John Hayes. On 1 March 1726, they persuaded him to partake in a
drinking contest, then killed him once he was intoxicated. The trio then
dismembered Hayes' body, subsequently discarding many of his body parts in a pond at
Marylebone. The head was cast into the
River Thames and was found the next day. It was displayed in the churchyard of
St Margaret's, Westminster, for several days, which resulted in John Hayes being identified. On 24 March, the trunk and limbs were discovered. Catherine Hayes and Billings had meanwhile been arrested on a warrant. Wood was captured shortly afterwards and confessed. Billings then admitted his complicity, but Hayes denied all knowledge of the murder. At the trial, Hayes pleaded 'not guilty', but was convicted of
petty treason, and sentenced to be
burned at the stake. Wood and Billings were sentenced to be
hanged, though Wood died in prison before the sentence could be carried out. The case excited much popular attention, and many noblemen and gentlemen attended the trial. ==Execution==
