Rescuers Fear Missing TV Doctor Lost in Dangerous Cave on Greek Island

The search for British TV doctor Michael Mosley, who went missing Wednesday on the Greek Island of Symi, has reportedly been narrowed down to a cave ominously known by locals as “The Abyss.”

Mosley’s wife, Clare Bailey, began ringing the alarm bells Wednesday evening after Mosley didn’t return at 7:30 p.m. from a walk he had departed on six hours prior.

Authorities began searching for Mosley that evening, believing he may have fallen on his walk. “Nothing at this stage can be ruled out,” a police source told The Daily Mail, Thursday. Mosley was last seen on a Saint Nikolas Beach at 1:30 p.m., according to a user in a Symi Facebook group who posted a photo of him. Authorities and search parties scoured the coast but found no sign of him.
