The family of Alan Eric Jeal have paid tribute to his “mild-mannered” and “gentle” character.
The body of 64 year-old Mr Jeal from Wadebridge was found naked apart from a pair of socks and a walking shoe on Perranporth beach more than a week ago.
After days of mystery his body was identified by family members from an artist’s impression yesterday.
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.”
CCTV footage from Wadebridge town centre shows Mr Jeal using a Barclays cash machine just before 12pm on February 24, the day before his corpse was found.
Police are treating the death as suspicious and the investigation is now focusing on the 64 year-olds last movements.
Detective Chief Inspector Dave Thorne, senior investigating officer, said: “Firstly, our thoughts are with Alan’s family and friends at this upsetting time and we will do everything we can to support them.
“Now that we know his identity, we can progress with the investigation and try to find out exactly what happened to him.
“He was last seen on Monday 24 February, the day before his body was discovered, and I would welcome information from anyone who knew Alan, or who saw him in the days leading up to his death.”
Items found on Perranporth beach including a Regatta jacket, wallet and photograph, are understood to have been Mr Jeal’s.
The photograph found in the wallet shows Mr Jeal when he was two years old in his family home.
It is not known whether the rucksack and woolly hat, found nearby on the same day that the body was found, are linked to him.
Mr Jeal lived alone and was not reported missing to police.
It is not known how he died, but police are not ruling out the possibility of murder.
Detective Chief Inspector Thorne said: “Murder is one possibility of many and we are certainly not ruling it out, but it is only one of many lines of enquiry.”
Anyone with information that could assist with the investigation should call police on 101, quoting log 381 of 1 March.
