He was present during the autopsy on the boy's body, and gave evidence at the murder trial of the four gang members, stating that the boy's injuries seemed consistent with a blow to the back of the neck. Witnesses had identified the victim as an Italian beggar, Carlo Ferriere, who exhibited white mice in a cage. Three of the gang were found guilty of the murder; before they were hanged, John Bishop and Thomas Williams confessed to drowning the boy in a well after drugging him with laudanum, stating, however, that the victim was actually from Lincolnshire. The third gang member, James May, had his sentence respited to transportation, but died on the way to Australia. The bodies of Bishop and Williams were dissected, the former at King's College London and their remains displayed.
