As the world mourns the loss of television presenter and healthy living advocate Michael Mosley, officials have revealed that he likely died of natural causes on the day he went missing on a Greek island.

The four-day search for the missing television presenter ended in tragedy when his body was discovered in a rocky area of the Greek island of Symi on Sunday, June 9. State television channel ERT reported that Mosley was found lying face up, with his head on a rock.

Following an initial post-mortem examination, it has now been confirmed that there were no injuries on his body, Greek police spokeswoman Konstantia Dimoglidou told the BBC.

His estimated time of death was around 4 pm local time on Wednesday, June 5th. Mosley had left his friends at Agios Nikolaos beach around 1:30 pm for a walk.

The position his body was found in also indicated that he likely died of natural causes, Dimoglidou said, adding that toxicology and histology reports will be carried out.

Following the discovery of Mosley’s body, members of the Symi crisis rescue volunteer team offered their “deepest condolences” to the wife, children and friends of the beloved television presenter.

“Our team was called in by island authorities to assist in the search investigation on the very first night of his disappearance and we immediately began with a first night search,” a statement said.

“We continued all the coming days to participate in the investigations together with firefighters, police officers and other volunteers, as always directed by the head of the investigation.

“High temperatures and rough spots made this mission particularly difficult, and unfortunately, the outcome was one we all know.”

As news of the tragic discovery broke, fans and those close to Mosley rushed to social media to pay tribute and offer their condolences, including Mosley’s wife, Clare, who expressed her devastation over the loss of her husband in a statement issued on her behalf.

“It’s devastating to have lost Michael, my wonderful, funny, kind and brilliant husband. We had an incredibly lucky life together. We loved each other very much,” the statement read.

Mosley was a familiar face on television in the United Kingdom for two decades, appearing on programs such as the BBC series Trust Me, I’m a Doctor, the BBC’s The One Show and ITV’s This Morning.

Mosley is survived by his wife, along with their three sons—Alex, Jack, and Daniel—and their daughter, Kate.
