MARLBOROUGH woman Rachel Smith has launched a campaign to prove her boyfriend Glyn Razzell is innocent of the murder of his estranged wife.

The 24-year-old, who lives with her parents at Gales Ground, has offered £5,000 to anyone who can prove that missing Highworth mother-of-four Linda Razzell is still alive.

Razzell, 43, was sentenced to life imprisonment in November at Bristol Crown Court after being convicted of murder, although Mrs Razzell's body has never been found.

Throughout the trial he protested his innocence, and he and Miss Smith have launched a website asking for any information about the whereabouts of Mrs Razzell, who disappeared on March 19, 2002.

Miss Smith, a former pupil of St John's School, Marlborough, who now works at Nationwide, said: "There is absolutely no doubt in my mind that he did not kill Linda.

"I have been by his side through the whole 18 months of the police investigation and the trial and I have seen all the evidence and there are just too many unanswered questions."
