That evening, having been formally charged with his daughter's murder and questioned as to why police had also discovered a third thigh bone, Fred confessed there were two further sets of human remains in his garden, and agreed to return to Cromwell Street to reveal the locations of both graves; one of whom he named as Shirley Robinson, whom he described as being a former tenant and a lesbian who had been heavily pregnant with his child at the time of her 1978 murder; the other victim he described (incorrectly) as being "Shirley's mate", but either could not or would not elaborate as to her identity. Both sets of remains were discovered on 28 February, and Fred was charged with both murders two days later.
