A post-mortem examination has been carried out on the body of 32-year-old Ian Quinn who was found dead in an apartment in Ongar, West Dublin yesterday.
Mr Quinn was found dead at an apartment at Annaly Grove in Ongar at around 4am.
Two women in their early 30s, who were arrested in connection with Mr Quinn's death, remain in custody at Blanchardstown Garda Station.
Gardaí say they are not releasing the results for operational reasons.
However, it is understood that Mr Quinn, who was originally from Tallaght, may have suffocated and was found with a plastic bag over his head.
As reported in today's Sunday World, Mr Quinn,a homeless ex-prisoner was well-known to gardai and had served a number of prison sentences for minor drug related crimes and public order offences.
Just days before his death, he was arrested for an alleged assault on A&E staff while attending Blanchardstown Hospital.
It is believed that he was currently staying in a hostel run by homeless champion Fr Peter McVerry.
Although he had a lengthy criminal record, Quinn was not regarded as a serious or gangland criminal.
