Carterton murder inquiry: Melvin Hillier killed 'by blunt impact'
A man who was found dead in Oxfordshire was killed by a "blunt impact to the head", a post-mortem test has revealed.
The body of Melvin Hillier, 52, from Witney, was found at The Tower Centre in Alvescot Road, Carterton, on Thursday morning.
Two men, aged 48 and 59, and a woman, 27, were arrested on suspicion of murder and remain in custody.
Thames Valley Police said the post-mortem examination found the cause of death to be a bleed on the brain.
The bleeding was caused by blunt impact to the head, it found, but further tests are to be carried out.
Det Ch Insp Ian Hunter said: "This is quite a complex investigation and we are continuing to speak with a number of people including those in custody about the circumstances leading up to Mr Hillier's death.
"We are keeping an open mind as the investigation progresses.
"Our thoughts are with his family and we have appointed a family liaison officer to support them at this time."
Supt Colin Paine, local police area commander, said: "I would like to assure the residents of Carterton and West Oxfordshire that incidents of this nature are rare.
"Our neighbourhood patrols will be in the area to address concerns from local residents and to provide additional reassurance while there are active police investigations in the area."
Two crime scenes have been cordoned off by police for forensic work to be carried out.
