Llywelyn Thomas murder: 'At least two' were at scene
Police investigating the murder of a widower in Cambridgeshire believe at least two people were in his home at the time of the killing.
The body of Llywelyn Thomas, 76, originally from south Wales, was found by police in his house in Ely Road, Chittering, on 18 December.
Cambridgeshire police believe Mr Thomas may have been killed in a burglary that went wrong.
Forensic tests are expected to continue for at least another three weeks.
Post-mortem tests found Mr Thomas died from face and head injuries. He was a widower with one adult son.
Det Supt Jeff Hill said: "We have been carrying out forensic examinations at the house since the discovery of Mr Thomas' body.
"We believe at least two people were in the house when he died, if there is a trace of them in the property we will find it."
His silver Rover 75 estate was stolen from his home and later found in Church Lane, Milton, north east of Cambridge.
A man, 22, arrested on suspicion of murder and a 21-year-old woman arrested on suspicion of assisting an offender were bailed until 15 February.
Police are appealing for witnesses who saw Mr Thomas' silver Rover between Chittering and Milton.
It had mechanical problems and would have made a lot of noise when being driven and could only manage low speeds, a police spokesman said.
