Police are understood to be searching the former garden of double murderer Christopher Halliwell.

Halliwell is serving life in prison for stabbing and strangling Becky Godden in 2003 and killing Sian O’Callaghan after abducting her as she left a nightclub in 2011.

During the last trial, the detective leading the investigation, DS Steve Fulcher, told a jury that Halliwell led him to believe he had killed more people.

He told Bristol Crown Court that Halliwell couldn’t remember the year he had killed Becky, saying it ‘led me to conclude that there were other victims’.

Now it is understood police are excavating two gardens outside his former home in Swindon, Wiltshire.

Sian, of Swindon, Wilts., was abducted and stabbed in the neck by Halliwell as she walked home from a nightclub, a court heard.

The force said the investigations are based on new information and they are not sure if they’ll find anything.

It is understood police have never searched the exterior of the property before and say the search is unrelated to the current owners.

Detective Chief Inspector Jeremy Carter, who is leading the investigation, said: ‘Searches are being conducted in the gardens and garages of two properties in Broad Street over this coming week.

“Whilst we do not have plans, at this stage, to search inside the properties there will be some disruption to the occupants.

‘I would like to make it clear that those living at the addresses have no involvement in the investigation and we thank them for their understanding and patience.

‘Although we are unable to comment on the nature of our enquiries, we can say that we acting on intelligence received.’
