A man found dead in his Aberdeen home died quickly with no obvious signs of struggle, police said.
The body of Wieslaw Koziolek, 49, was discovered at a property in Balnagask Avenue, Torry, by a housemate on September 29.
Detective Chief Inspector Iain Smith said Mr Koziolek, 49, a Polish national and skilled joiner, died after being injured.
But nobody heard any disturbance around the time, the police officer confirmed.
Mr Smith said: “He was found in a room within the flat by someone he shares with.
“There were no reports of any disturbance prior to this incident.
“The death is still being treated as suspicious and the investigation is trying to establish whether any criminality caused the death.”
He said results of full forensic tests would rule out whether Mr Koziolek had been involved in a struggle before he died. (**please keep this in).
Suicide has not been ruled out at this stage, the officer said.
Mr Smith said all of the victim’s flatmates had been interviewed but none of them had been arrested in connection with the death.
The senior officer said he was keen to establish why Mr Koziolek had made two trips into the city centre on the morning before he died.
It is thought he returned home to Balnagask Avenue up to one hour before his body was found, at 1.30pm.
Mr Smith said: “We think he was either going for some shopping or to meet some friends but we are not clear whether he was successful in doing this.”
Mr Koziolek is known to have moved to Aberdeen several years ago and worked as a joiner. He also spent some time in Dundee.
The Pole was forced to give up work due to ill health and had been living in the homeless accommodation at Balnagask Avenue for several months.
Mr Smith added: “He led a quiet lifestyle but he did have friends. We are still keen to speak to people who may have known him to see what his life was like before he died.”
Mr Koziolek’s relatives in Edinburgh and Poland have been informed of his death.
The officer described the man’s death as a “tragic set of circumstances.”
