Albert Donoghue into confessing to killing Mitchell led to him becoming a crown witness and testifying against them. Ron, Reg and Charlie Kray and Freddie Foreman were all acquitted of Mitchell's murder, due to lack of evidence and the perceived unreliability of Donoghue's testimony. Reg Kray was found guilty of conspiring to effect Mitchell's escape from Dartmoor, for which he received a five-year sentence to run concurrently with his other sentences. Donoghue and another Firm member, John Dickson, pleaded guilty to harbouring Mitchell and respectively received 18-month and nine-month sentences. In his 1996 autobiography Respect, Foreman admitted to shooting Mitchell as a favour to the Krays; Donoghue said Foreman was paid £1,000 for it. Foreman was arrested and questioned by police after repeating his confession in a 2000 television documentary, but the Crown Prosecution Service announced that it would not be re-opening the case, due to the then extant double jeopardy law. Mitchell's escape, confinement and subsequent murder were the subject of the 2019 film The Krays' Mad Axeman, in which Mitchell was portrayed by Diarmaid Murtagh.
