CCTV footage has been released by Suffolk Police showing Ms Murton on a footpath on the edge of Nacton and walking behind Amberfield Drive in the direction of Decoy Wood on the afternoon she went missing.
She is about 5ft 7in with short dark hair and glasses and was said to be wearing a purple jacket with blue trousers and carrying a large shoulder bag when she went missing.
Det Supt Pearse added Ms Murton’s family was still “very concerned”, but grateful to those that had given them space.
“They did want me to pass on their personal thanks to all those people that have been out there in the cold, in the rain, this week and last week looking for Christine,” he continued.
“They are eternally grateful”.
