Police have today revealed that a man who might have been murdered had a sock shoved into the mouth when he was found dead on Perranporth beach last month.
Investigators have also said that CCTV footage shows Alan Eric Jeal, from Wadebridge, was in Truro the night before his body was spotted by a dog walker.
Police remained baffled as to why or how Mr Jeal, 64, ended up with the sock in his mouth. He was also naked apart from a walking shoe and a pair socks.
DCI Dave Thorne, senior investigating officer, said: “We can’t think of an explanation as to why it would be there and this is one of the reasons we are treating Alan’s death as suspicious.
“It would be quite difficult to have got in there by accident, so it would seem that either he or someone else put it there.
“Officers are keeping an open mind as to the cause of his death.
“Murder is one possibility we are considering, however his death may have been caused by accident or suicide.
“We would also to hear from anyone who may have witnessed the discovery of his body on the beach on Tuesday 25 February and may have recorded the incident on their camera or mobile phone.”
The CCTV footage places Mr Jeal in Truro city centre on the night of February 24.
It was believed he got the number 594 bus from Wadebridge to Lemon Quay in Truro, arriving at the bus station at 6.14pm.
He was seen walking towards the public toilets at The Leats, and last seen at 6.36pm in Boscawen Street.
Officers are trying to find out where Mr Jeal went after that and how he got to Perranporth.
DCI Dave Thorne, said: “We are keen to speak to anyone who saw Alan on Monday 24 February, whether walking, on public transport or in a car.
“We have traced his movements up until 6.36pm in Truro city centre but we need the public’s help in establishing where he went after that.”
Police are still looking at CCTV footage in Truro, Perranporth and several towns and villages in the area.
They are also taking to tide experts to try and establish where Mr Jeal went in to the water.
“We know he was found just before high tide which tends to flow west to east, so he could have gone in to the water further west towards St Agnes, or potentially he could have come from further up the beach and just got washed around in the surf,” added DCI Thorne.
Mr Jeal lived alone and was not reported missing to police.
He is described as having lived a solitary life, but was well known in the surfing community.
A spokesman from the family said: “Alan was a mild-mannered, gentle man who was very interested in minerals, mining and surfing.
"We are shocked and deeply saddened that Alan's life has been cut short and are desperate for answers as to what happened.
“We appeal for anyone with information about Alan’s life and last movements to contact police.”
Police are still unsure how Mr Jeal died, but the multiple injuries found on his body are inconsistent with drowning and cannot be easily explained.
They are waiting for post mortem results to confirm a time of death and whether he died before or after he entered the water.
Anyone with any information should call the police on 101, quoting log 381 of 1 March.
