Police have issued a new image of the bag thought to have been used by the man whose body was found on Perranporth beach.
The body of Alan Jeal was discovered with a sock in his mouth on the beach near the Watering Hole bar on February 25.
Mr Jeal, from Wadebridge, was captured on camera in Truro on the day before his body was found and police are trying to piece together his last movements.
It is believed that Mr Jeal got the number 594 bus from Wadebridge to the Lemon Quay area of Truro, arriving at the bus station at 6.14pm. He was seen walking towards the public toilets at The Leats, and was last seen at 6.36pm in Boscawen Street.
Officers are trying to find out where the 64-year-old went after that, and how he got to Perranporth.
Detective Chief Inspector Dave Thorne, senior investigating officer, 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 said multiple injuries were found on the body which were inconsistent with drowning and cannot be easily explained.
