The dental records of missing British hiker Esther Dingley are being sent to French authorities following the discovery of possible human remains in the Pyrenees.
Ms Dingley, 37, was last seen walking alone in the mountains near the French-Spanish border on 22 November last year.
She was due to return from a three-day solo trek and travel home to the UK with her partner Dan Colegate but never returned.
Her mother Ria Byrant, 74, told The Sunday Times that French police have requested her daughter’s dental records after local police announced on Friday that they may have discovered human remains near her last known location.
“The dentist is sending a scan of Esther’s teeth. We have to send it to the consulate in Bordeaux,” she told the newspaper.
Ms Bryant moved to the Pyrenees in June to help look for her daughter.
She was planning to return to Britain this month, but told the paper she has changed her plans following the developments.
Charity LBT Global, which supports the families of missing people, previously said it was “aware of the discovery of what may be human remains close to the last known location of Esther Dingley”.
“The family have been informed of the discovery and we are supporting them now,” it wrote in a statement.
French police chief Jean Marc Bordinaro was quoted as saying: “We cannot say anything at the moment because the discovery of the bones is too recent and they must be properly analysed.”
Earlier this year Ms Dingley’s partner revealed authorities were “looking at options beyond a mountain accident“.
They had been travelling around Europe in a campervan together since 2014.
