By Katie Mccabe, BBC News – They were in a keg in a garden in their suburban home when they were discovered on Wednesday, with a small piece of meat in their mouths and the front of their stomach.
A coroner has ruled out foul play, but the couple’s death remains under investigation.
The bodies of two other men were found in their home in Manchester, and a fourth man, aged 35, was also taken to hospital.
The family had recently moved into the house and had no idea of the couple had been there.
Detective Constable Ian Jones, of Greater Manchester Police, said: “We have been in touch with the local coroner and are still awaiting the results of that examination.”
At this stage we have no information to suggest the body of the other two men was the body found by the police.
“However, it is our belief that the man was killed by the killer.”
It is a very sad and sad situation and we would ask anyone who may have been at the house to come forward and speak to us.
“We have spoken to a number of witnesses who have come forward but we do not believe there is any link to this particular case.”
Our priority is to find the real suspect and bring them to justice.
