The remains were later confirmed to be a piece of Esther's skull, however extensive subsequent searches have so far not revealed any further clues as to what happened to her. Esther Dingley is pictured here on the "open" Esther & Dan Facebook page. Missing British hiker Esther Dingley may have been murdered - 10 Aug 2021 Police investigating her death have now said publicly for the first time that she may have been murdered. French prosecutor Christophe Amunzateguy, who is leading the investigation, said they are not ruling out that her death may not have been accidental. Esther, from Durham, was travelling with boyfriend Dan Colegate but was on a solo trek when she vanished. The experienced hiker had numerous items of kit with her, including a rucksack and brightly coloured survival gear, but extensive searches using drones and on foot have not found any other remains or any of her clothes or equipment. Search teams believed a wolf or wild bear may have moved the bone fragment close to a well-used trail after Esther died in a fall. But that theory should have led to the discovery of clothes or equipment scattered somewhere nearby.
