DETECTIVES investigating the murder of Becky Godden-Edwards have revealed more than 600 items have been recovered from a pond in Ramsbury where the boots of murdered Sian O'Callaghan were found. 

Earlier this year, around 60 items of female clothing were uncovered following the grim discovery.

Today, police revealed a further 600 items have now been found, ranging from a shot gun to beer bottles.

They have also released information on a car they believe was used in her abduction.

The last sighting of Becky was by a police officer on 27 December 2002 in Manchester Road, and there still remains a period where her movements are unaccounted for.

The news of her murder only broke in April 2011, on what would have been her 29th birthday.

After the case was revisited under the leadership of cold-case specialist, DCI Sean Memory, the car that is thought to have been used in her murder has now been identified.

The silver Volvo, registration T661 LGP, was used in the Swindon area around the time of her disappearance and strong evidence has emerged to place her inside the car following the last sighting of her.

The vehicle drops off the grid after being sold at ASM auctions in Oxfordshire in 2004, and may have been scrapped, sold on, or shipped out of the country.

DCI Memory said: “I think that Becky has been in this car in and around the time that she was murdered so I am very keen to find out where it is now.

“I have done a review of the case and have been able to narrow down that Becky was last seen alive by a police officer in December 2002.

“There have then been no sightings of her throughout 2003. I believe this car may well have been used in the commission of this crime towards the end of 2002 and beginning of 2003.”

Detectives have spoken to the previous owner of the car but are not able to confirm their identity.

“I cannot comment on who may have owned that car at the time, but we know the car was sold at auction in 2004, possibly bought by an Irish male who may have bought some other cars,” added DCI Memory.

“It was not registered after it was sold, and the last person who registered it was the one who sold it at auction. I have been to the DVLA and it simply drops off the grid at that point.

"The auction house have not retained the details of the person who bought it. It has not come onto our records previously, and was sold for £5,000 in 2004 so it certainly was not sold for parts. It must have been driven somewhere since, either in this country or in Ireland.

“It may well have been scrapped or taken overseas. I want to determine what has happened to it, as it may be sitting in a family’s field somewhere not being used.

“Until we have more information I am very open-minded. I am really appealing for the person who bought it because they can start the chain to trace where it went. They have no involvement other than as a potential witness.”

Since the case was reviewed last year a number of new developments have been uncovered, including the find of one of Becky’s bones in April at the field in Eastleach where her body was hidden.

“We did a significant search of the pond near Ramsbury over a 10 day period,” said DCI Memory.

“While there we recovered 660 different items and we are currently sifting through them to identify those deemed significant. Those items range as far and wide as a shotgun to cans and bottles. These may or may not have some connection and we are waiting for forensics to come back on all of them. We are going through a system to determine when that property arrived in that area.

“That is quite painstaking work and a significant amount for the team to go through.

“We have spoken to some people in the area and there is some indication of one area being used for flytipping, but these items were buried which makes it quite unusual. It is an isolated location and only those with local knowledge would have used it.”

A spokesman for Wiltshire Police said: “Wiltshire Police continue to appeal to the public to contact us with any information relating to Becky’s disappearance in early 2003. All information will be treated in the strictest confidence. If you have information please call 101 or alternatively if you wish to remain anonymous please call Crimestoppers on 0800 555 111.

“Wiltshire Police continue to offer support to Becky’s family. The Major Investigation Team intend to do everything possible to ensure Becky’s family get the closure they deserve by bringing her killer to justice.”
