A police investigation has concluded that Josh Clayton's death was not suspicious.
The 23-year-old's body was found on rocks off Tean on September 23, 2015, ten days after he went missing following a party on Tresco.
An inquest into his death was halted in January 2017 after new evidence emerged that he had been involved in an altercation.
Josh's family have been critical of the original police investigation and previously insisted that his death was "definitely not an accident".
However, a new police investigation has now concluded that "no suspicious activity was found and no suspects were identified".
Detective Superintendent Steve Parker of Devon and Cornwall Police said in a statement: "We have now concluded our investigation on behalf of the coroner.
"We have kept an open mind throughout the investigation. No suspicious activity was found and no suspects were identified.
"We have kept the family informed throughout this process and they are aware of the outcome of the report.
"The file has now been submitted to the coroner."
