The 12 victims of Fred and Rosemary West

Heather West was the first child of Fred and Rosemary West, born in Gloucester on 17 October 1970. Her murder demonstrated the depths of evil the couple were prepared to plummet to.

She was 16 when she was murdered in 1987. She was the first victim whose body was found at 25 Cromwell Street and is believed to have been the last victim of the Wests' killing spree.

She had lived with her family in Midland Road until 1972, when they moved to Cromwell Street.

She was "rebellious, difficult, and refused to collaborate with her father's plans", Mr Wansall said.

She and her sister would try to protect each other from their father, and Mr Wansall said he believed she had threatened to go to the police about her father, which in his view is why she was killed.

She had just finished her GCSE examinations when she went missing. Her parents never reported her "disappearance", although they told various people they had.

In reality, Heather West had been murdered and was buried under the garden patio.
