CCTV footage appears to show TV presenter Dr Michael Mosley disappearing from view as he walks down a hillside near where the body was found, the BBC has been told.
Dr Mosley’s body was found four days after he went missing on the Greek island of Symi and an autopsy is due to be carried out on Monday.
It is understood that the coroner was unable from the outset to determine whether Dr Mosley had collapsed due to the condition of the body.
The coroner has arrived in neighboring Rhode Island to conduct an autopsy and is believed to have ruled out foul play.
Dr Mosley’s body was found on a hillside near Agia Marina beach bar on Sunday.
The BBC has been informed of, but has not seen, video filmed nearby which is said to show Dr Mosley’s final moments as he walked down a ramp before disappearing behind a wall.
The 67-year-old father of four went missing on Wednesday after taking a walk from Agios Nikolaos beach.
His wife Dr Claire Bailey Mosley has paid tribute to her “wonderful, funny, kind and brilliant” husband after the “devastating” news that his body was found.
Dr Bailey Mosley said: “We had a very lucky life together.
“We are very much in love and very happy together.”
CCTV footage showed Dr Mosley walking through rocky terrain to the other side of the bay in sweltering heat.
“We are relieved that he almost made it,” his wife said in a statement.
“He made an incredible climb, took the wrong route and collapsed in a place where an extensive search team could not easily find him.”
Dr Mosley studied medicine and qualified as a doctor in London and has spent the past two decades working as a presenter, documentary maker, journalist and author.
He is known for TV shows including Trust Me, I’m a Doctor and BBC Radio 4’s Just One Thing podcast. He also writes a column for the Daily Mail.
Mr. Mosley has been an advocate of intermittent fasting diets, including the 5:2 diet and the Fast 800 diet.
Dr Saleha Ahsan, who co-hosts Trust Me I’m a Doctor with Dr Mosley, told BBC Breakfast she was initially “scared” to accept the role but he “put me at ease almost immediately” ”.
She added: “That very personable, approachable character [that] What you see on TV is what he looks like in real life.
“He did incredible things for medicine and public health that I think very few people have done.”
