THE mother of murdered fitness fanatic Dawn Walker has called on the police to reopen its investigation to catch her killer's accomplice.

Salesman Kevin Nunn, 48, was jailed for 22 years for the murder of 37-year-old Miss Walker and setting her body alight next to the River Lark near Bury St Edmunds in February 2005.

Miss Walker, of Fornham St Martin, had recently ended her two-year relationship with Nunn prior to her murder.

Throughout the trial it was claimed Nunn, formerly of Woolpit, had an accomplice, though a man accused of helping dispose of Miss Walker's body was acquitted during the case.

Suffolk police said it had no current lines of inquiry relating to the case.

But Miss Walker's mother Jean, who lives in Bury St Edmunds, is now urging the police to hunt down Nunn's accomplice with renewed vigour.

“I would call for the investigation to be reopened to find the person who helped him. We do wonder who the second person was and we do speak to them (the police) about it.

“I think given time they will catch the person who helped him.”

She said the family had not yet been able to come to terms with Miss Walker's death - particularly as no accomplice had been caught. And Mrs Walker told how her family was still struggling with legal issues in the aftermath of her murder, such as the settling of her daughter's estate.

She said whoever was responsible for helping dispose of her daughter's body was still at large and needed to be brought to justice.

A spokeswoman for Suffolk police said: “Kevin Nunn was convicted of the murder of Dawn Walker at Ipswich Crown Court in November 2006.

“There are no current lines of inquiry in this case.”

Earlier this week, the EADT revealed how Nunn's family had hired a London-based legal team as part of a campaign to clear his name.

The Nunn family, which is offering a £50,000 reward for information which leads to the quashing of his conviction, insists he is the victim of a miscarriage of justice and has pledged to fight for an appeal.

But, last year judges at London's Court of Appeal rejected Nunn's application to appeal the conviction, claiming there was “ample evidence” against him.
