Despite Fred's insistence that his wife held no knowledge of any of the murders, investigators suspected otherwise. Rose was arrested on 20 April 1994, initially on offences relating to the rape of an 11-year-old girl, and the physical assault of an eight-year-old boy—both charges dating from the mid-1970s. The following day, she was refused bail, and transferred to Pucklechurch Prison to be held in the maximum security wing. Here, she was questioned more closely about the murders, in particular those of her daughter Heather and Lynda Gough, and on 25 April she was formally charged with Gough's murder.
