Susan Rushworth, a mother-of-three and grandmother, vanished in June, 2009.

She was the first of Stephen Griffiths’s victims but no trace of her has yet been found.

Miss Rushworth, a heroin addict who was 43 at the time of her disappearance, had spent the evening of Sunday, June 21, last year with her family in Thornton. The following morning she caught a bus to her home address, a flat in Oak Villas, Manningham.

Last Christmas, her son James, then 24, and daughter Kirsty, then 21, made an emotional public plea for help to find her – six months after her disappearance.

They wept as they pleaded through the Telegraph & Argus: “Someone knows what has happened to our mum. We miss her so much. We have not had a Christmas without her before and it is her birthday on New Year’s Eve. We ask anyone who can put an end to our misery to come forward.”
