An elderly married couple found dead in their home may have been victims of a bungled robbery, police have said.
A murder inquiry has been launched into the suspicious deaths
The pair, who were in their early 70s were discovered by a female relative at their Kent home in Abbey Street, Faversham, on Wednesday morning.
Det Ch Insp Dean Barnes said: "It could have been a burglary gone wrong. It could have been a number of things."
He said there were no signs of forced entry but the house appeared to have been searched.
"What the individuals concerned were searching for or what they may or may not have got we will not speculate on," he said.
He added that he was unable to confirm when the couple were murdered or how they died.
Their purple Daihatsu Sirion car was found burned out just over a mile away from their home in the Bysing Wood Road area of the town on Monday evening.
Mr Barnes said: "It appears that the vehicle may have been abandoned as a consequence of what went on at the house earlier on."
He said police called at the "well-liked" couple's home later that evening but there was no reply."
He added: "Police then attended again the following morning and left a note. I believe there were several more calls to the address throughout Tuesday.
"There was nothing that would draw their attention to anything untoward.
"It could well have been that the couple were on holiday and their car had been stolen."
He confirmed a double murder investigation had been launched into the "extremely distasteful crime"
Mr Barnes appealed to anyone who saw the couple after 1245 GMT on Saturday, when they were last seen, or who saw anything suspicious in the area over the weekend.
Kent Police are yet to formally identify the pair.
