A POST Mortem is expected to be conducted today to determine if the foul play was involved in the death of an Armidale man at the weekend.
The body of 48-year-old Adolfo Marquez was found on the kitchen floor of a unit complex on Barney St on Sunday morning.
Police were called to the scene about 10am after residents reported a foul odour at Mr Marquez's flat.
Officers say Mr Marquez sustained no visible injuries and there were no signs of forced entry to the unit, but they are treating his death as suspicious until proven otherwise.
New England Local Area Command crime manager Detective Inspector Greig Sister said officers have since established a crime scene at the unit complex which was examined by forensics officers.
"We treat all deaths as suspicious until proven otherwise but this is one in particular we have some concerns about," Inspector Stier said,
"He (Mr Marquez) was seen by police last week in the company of a number of other people who are known to police.
"It appears he hasn't been seen after Tuesday until his body was located yesterday.
"We're looking at a number of avenues which may have contributed to his death and are interviewing a number of people today."
The investigation is being headed up by Armidale detectives who are currently preparing a report for the coroner.
Inspector Stier urged anyone with information about Mr Marquez's death or his movements in the days before his body was discovered, to contact Armidale Police Station on 6771 0699.
