Police have released a “chilling last sighting” of a missing mum who vanished 11 days ago whilst on a walk.

Christine Stenson, 66, of the Wheatley area in Doncaster, was last spotted walking along Cantley Lane in the direction of Rose Cemetery on August 12 at 5.57pm.

She had been dropped off at an address in Hawke Road at around 5.05pm, and South Yorkshire Police believe she only spent five minutes at the property before leaving.

The 66-year-old was then spotted seven minutes later on Thorne Road, before a fourth sighting caught her at Racecourse Roundabout at 5.40pm.

They said they had “deployed numerous resources” in trying to locate the missing 66-year-old.

A force statement said: “We have deployed numerous resources in our work to find Christine, including specialist search teams, off-road bike teams, mounted officers, drones, and specialist search dogs, and have had support from a National Police Air Service helicopter utilising thermal imaging technology.

“Unfortunately, despite our best efforts, we are yet to locate Christine, and the search continues this week with our specialist teams.

“Enquiries are ongoing all day every day, with officers carrying out CCTV trawls and house to house calls.”

South Yorkshire Police are appealing for footage taken between 5.45pm and 8.00pm that day to see which way she may have travelled

She has been described as being white, 5ft 5ins (1.7m) tall, with very long, grey hair.

Stenson was last seen wearing a black vest top with a floral pattern and orange shorts, officers added.

Officers had previously said they were “particularly interested” in footage between 5.45pm to 8.00pm on August 12 that could indicate which direction she may have travelled.
