DC Dale Purcell, from the Major Crime Unit, who is investigating the case, said: "The combination of where the body was discovered and the circumstances, i.e. that the body was dumped in plastic bags, suggests third party involvement."
However pathologist Dr Robert Chapman was unsure whether the blows had been inflicted while Mr Danilevicius was alive or after he had died.
There was no evidence of 'defensive action', to suggest the victim had tried to block the 'assailant'.
Recording a verdict of unlawful killing, Mr Bedford said: "Why would someone go to the trouble of wrapping the body up and depositing it in a remote, rural location? Mr Chapman is being cautious, which we can't be critical of.
"But because of all the injurives that have come to light, this is being treated as an unlawful killing by police and from the remit of my inquiry, I have no doubt he was unlawfully killed.
"The report is not able to confirm if he was dead before he received the blows to the head or after.
"That doesn't explain why explain how he came to be wrapped in plastic bags and a blanket and then dumped."
He added: "I hope this inquest is at least some small solace to his family.
"It is a tragedy his mother died without having any closure about what happened to her son."
