The Babes in the Wood Murders were the murders of two nine-year-old girls, Nicola Fellows and Karen Hadaway, on 9 October 1986, by a 20-year-old local roofer, Russell Bishop in Wild Park, Moulsecoomb, Brighton, Sussex, England. Bishop was tried and acquitted in 1987. The case remained open until 10 December 2018, when Bishop was found guilty of the murders in a second trial. The investigation into the two girls' murders is the largest and longest-running inquiry ever conducted by Sussex Police.
