Police are searching a field close to where murdered mother Linda Razzell went missing 17 years ago. She was last seen on March 19, 2002, in Swindon, Wiltshire after driving to work at a college and her mobile phone was found dumped in a nearby alleyway. In 2003, her estranged husband Glyn Razzell was jailed for life for the murder of Linda, 41. The search is taking place less than half-a-mile from Mrs Razzell's former home in Pentylands Close after police were given a tip-off by members of the public.

Today a blue forensic tent was erected in a field near Pentylands Lane, in Highworth, Swindon, Wiltshire. The search is taking place less than half-a-mile from Mrs Razzell's former home in Pentylands Close. Wiltshire Police say detectives are keeping 'an open mind' as to whether the search is connected with the college worker's murder. A police spokeswoman said: 'We are conducting some local enquiries in the Highworth area following information from a member of the public. 'As part of these enquiries, we have cordoned off an area in a field off Pentylands Lane. 'People in the local area are, therefore, likely to see an increased police presence in this area over the weekend. Our enquiries also include the use of police dogs. 'As these enquiries are at an early stage, it would be inappropriate to comment at further at this time.' In 2003, former insurance investment manager Glyn Razzell was jailed for life for the murder of his estranged wife Linda, 41 Last year a BBC documentary raised doubts over Mr Razzell's guilt. Despite Mr Razzell's conviction, his wife's murder is one of several unsolved cases in the area linked with killer taxi driver Christopher Halliwell. Halliwell, 55, was convicted of stabbing and strangling Becky Godden, 20, in 2003 and abducting and killing Sian O'Callaghan, 22, in Swindon, in 2011. The whereabouts of Vietnamese immigrant Thi Hai Nguyen, 20, have also been unknown since she went missing from her temporary home in Swindon in June 2005.

In April 2002, police release CCTV images and an emotional witness appeal is made by Mr Razzell and her boyfriend, Gregory Worrall. On May 17, 2002 Mr Razzell was charged with his wife's murder. Razzell was convicted of his wife's murder in November 2003, following a month-long trial at Bristol Crown Court. All rights reserved for this news site dailymail and under his responsibility
