Robertson was first able to appear at Widnes Police Court on 12th September, when he was committed to the Assizes for trial. On 28th October at the Liverpool Assizes his defence pleaded insanity but this was rejected and Robertson was found guilty of murder and sentenced to death. He was hanged by Thomas Pierrepoint on the morning of 6th December, walking firmly and unassisted to the scaffold.
