Police are still appealing for any information about Julie's whereabouts and is urging anyone who has seen her in recent weeks to get in touch.
Cambridgeshire Police also confirmed it had carried out a search on Grounds Avenue in the nearby town of March in connection with the investigation.
"We know she has links to places in the surrounding area including March, Manea, and Chatteris so I would urge people who live in those areas to consider if they have information that could be of use to our inquiry.
A "no-body" murder investigation was launched on Friday and now Karl Hutchings, 47, from the same village, has been charged with her murder.
