Within a year, Pearce escaped a second time, joined by a young convict named Thomas Cox. Pearce was captured within ten days and taken to the Supreme Court of Van Diemen's Land in Hobart, where he was tried and convicted of murdering and cannibalising Thomas Cox. Observers noted Pearce did not look like a cannibal. He was only in height, which was under average for that time, but had a strong wiry frame. He did not seem to be someone who was "laden with the weight of human blood, and believed to have banqueted on human flesh" as the "Hobart Town Gazette" wrote on 25 June 1824. His captors had found parts of Cox's body in Pearce's pockets, even though he still had food left, and his guilt was beyond doubt this time. Pearce confessed he had killed Cox because when they reached King's River, he discovered that Cox could not swim. Pearce was the first felon to be executed by the new Supreme Court and the first confessed cannibal to pass through the Tasmanian court system.
