Friends of missing mother-of-two Nicola Bulley say they hope the help of a specialist underwater rescue team will give her family answers.
Private diving team Specialist Group International, led by forensic expert Peter Faulding, will help police search for Ms Bulley, who vanished while walking her dog near the River Wyre in Lancashire more than a week ago.
Police have been working on the theory the 45-year-old fell in the river but her family and friends have questioned that, saying there is still no evidence.
Speaking to broadcasters on Monday, Ms Bulley’s friend Emma White said the family asked Mr Faulding and his company for help.
She told BBC Breakfast: “Following the hypothesis of the police that Nicola was in the river, we need some evidence to back that up either way and I feel Peter and his amazing bit of kit … is going to come and sweep the river bed and give us answers.”
Speaking to ITV’s Good Morning Britain, Ms White added: “We hope they uncover nothing, like the police have done for the last 10 days, and we hope Nicola is not in that river.”
Mr Faulding said his team will use high-tech sonar, which can see “every stick and stone lying on the riverbed”.
He told Sky News: “Let’s get this water searched so it can be either confirmed or denied if Nicola is actually in this river.”
He added: “This is a particularly long stretch of river for them (police) to do because they’re doubling up as a dive team as well, so this is a huge task for the police.”
Lancashire Police believe Ms Bulley went missing in “a 10-minute window” on January 27 while walking her dog, Willow, in the village of St Michael’s on Wyre after dropping off her daughters – aged six and nine – at school.
She logged in to a Microsoft Teams call at 9.01am. The remote meeting ended at 9.30am with her phone still connected.
She was seen by another dog walker at 9.10am – the last known sighting – and police traced telephony records of her mobile phone as it remained on a bench overlooking the river at 9.20am.
The device was found by a dog walker at around 9.35am, with Willow nearby.
New images, taken from her home’s doorbell camera on the day she disappeared and released by her family, show Ms Bulley loading her car before driving her children to school.
She was wearing a long black coat and her blonde hair was in a ponytail.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
