The book, Bedfordshire Casebook, A reinvestigation into murders and other Crimes by Paul Heslop, 2004 The Book Castle, Dunstable ISBN 1 903747 57 0 includes this trial in the dozen cases covered.
Welch and Worsley were charged with murder, and a further charge of robbery was added, but the murder charge against Welch was dropped, which meant he could give evidence against Worsley. Worsley was found guilty, sentenced to death and hanged at Bedford on 31 March 1868.
Welch then changed his plea to guilty of robbery with violence, after Worsley had been found guilty of murder, and was given 14 years and having served 3 months was given a free pardon.
Welch was described as '"a man whose career for the last 16 years has been one of violence and crime'.
Interesting that Welch and Worsley had been drinking before the murder at the Royal Oak, Round Green, Luton, where the landlord and his wife were John and Mary Ann Gazeley.
