A source close to the investigation told this newspaper that no date is in sight for release of the dogs to their owners.
“We won’t be releasing the dogs until the specialist forensic work is complete,” the source said.
“It’s a really complex case, it’s pretty much unprecedented and there have been a lot of challenges with it if I’m honest, it’s just one of those really unusual ones.”
Detective Inspector Josephine Horner said: “This is a tragic incident in which a young woman lost her life. I know it has caused real concern locally and I thank the community for bearing with us whilst we conducted our enquiries.
“The criminal investigation has now concluded and the information we have gathered will be passed to the Surrey Coroner to assist in the coronial process.
“The dogs continue to be cared for at private kennels to ensure their welfare and their owners are being kept informed.
“We appreciate this is a difficult and uncertain process for them as the forensic work continues.”
