Police have made a fresh appeal for CCTV and dashcam footage that could help in the search for a missing mother-of-five.
Sarah Wellgreen was last seen on October 9 in Bazes Shaw, New Ash Green, Kent, and has not been in touch with her family since. She was reported missing on October 11.
The 46-year-old’s disappearance is being treated as a potential murder by police.
Detectives from the Kent and Essex Serious Crime Directorate want to identify anyone driving or walking in the New Ash Green area between 8pm on October 9 and 7am on October 10.
Detective chief inspector Ivan Beasley said: “While we have recovered more than 2,000 hours of CCTV, I would urge anyone with cameras within a five-mile radius of New Ash Green who has not yet contacted us, to get in touch.
“It is entirely possible they have not called because they believe it will contain nothing of relevance. My message would be, please send it to us and let my investigators decide.”
He also urged motorists who may have captured dashcam footage from the area at the relevant times to get in touch.
Since Ms Wellgreen’s disappearance, police have twice searched her home for clues to her whereabouts.
Divers have entered the River Darent in Dartford town centre, police and council workers have searched drains and the fire service provided a drone.
Hundreds of members of the public have also volunteered to help.
Ms Wellgreen’s disappearance has previously been described as “entirely out of character”, with her black iPhone 4 being the only item missing from her home.
Police say her car was left at her home address and there have been no new transactions on her bank or credit cards.
Ms Wellgreen is white, around 5ft 7in tall, of medium build, with green eyes and straight brown shoulder-length hair.
A man in his 30s was arrested on October 16 and released on bail until November 16. Police have said they will not yet disclose what he has been arrested on suspicion of.
