In October 1972, the Wests hired 17-year-old Caroline Owens as their children's nanny. They had picked her up one night on a secluded country road as she hitchhiked from Tewkesbury to her Cinderford home, having visited her boyfriend. Learning that Owens disliked her stepfather and was looking for a job, the Wests offered her part-time employment as a nanny to the three children then in their household, with a promise she would be driven home each Tuesday. Several days later, Owens moved into 25 Cromwell Street, sharing a room with Anna Marie, whom Owens noted was "very withdrawn".
