Police are digging up the garden of a house where double killer Christopher Halliwell once lived.
The ex-taxi driver is serving a life sentence for murdering 20-year-old Becky Godden in 2003 and 22-year-old Sian O’Callaghan in 2011.
Wiltshire Police said specialist officers are “carrying out excavation works within gardens of two properties within Broad Street, Swindon” as part of an ongoing investigation.
The force added: “This relates to intelligence that the force has received.”
Sky News understands that the garden and garage of one house is being searched.
Teams of forensics officers, as well as diggers, are expected to be at the addresses for about a week.
