After his arrest in February 1994, Fred confided to his appropriate adult, Janet Leach, that Rose murdered Shirley Robinson and had assisted in her dismemberment, personally removing Robinson's foetus from the womb in the process. Another body found at Cromwell Street was that of the Wests' daughter, Heather, who was murdered in June 1987 at the age of 16, after being abused by her parents all her life. Her dismembered body was placed under their family's patio. It is said that Heather began to tell her friends about the abuse occurring in her home. Barry, her younger brother, would later describe watching, as a seven-year-old, his mother kick Heather repeatedly in the head until she was no longer moving. The Wests told friends and concerned parties that she had left home to work at a Devonshire holiday village and on one occasion, fabricated a phone call, supposedly from Heather, to allay her siblings' suspicions regarding their sister's disappearance. Fred would even taunt his children when they misbehaved by jokingly stating, "If you don't behave, you'll end up under the patio like Heather." This was the last known murder that the pair committed.
