 Two others were also charged and found guilty of Brett's murder, Thomas Maguire and Edward O'Meagher Condon, but their death sentences were overturned: O 'Meagher Condon through the intercession of the United States government – he was an American citizen – and Maguire because the evidence given against him was considered unsatisfactory. Allen, Larkin, and O'Brien were publicly hanged on a temporary structure built on the wall of Salford Gaol, on 23 November 1867, in front of a crowd of 8,000 – 10,000.
