There is a small possibility that the pair may have been involved in an earlier homicide that resulted in another woman being executed. In 1899, Louise Masset was tried for the murder of her young son Manfred, whose body was found in the ladies' lavatory at Dalston Junction railway station. Circumstantial evidence suggested that Louise was the murderer, and the killing was to be rid of a supposed encumbrance due to her wanting to marry a man named Lucas. However, in her claims of innocence, Louise said she had taken Manfred out of the care of one woman to give him to two ladies she met who had an establishment for the care of growing children. The police claimed they made some effort in looking for the two women, but the extent of their investigation is unknown. In any event, Louise Masset was tried and convicted of the murder and, despite a petition for mercy, was executed on 9 January 1900.
