Gardaí investigating the murder of Philip Finnegan, whose body was discovered in Rahin Wood in Co Kildare on Friday night, suspect those involved in the killing may have been disturbed during the crime.
The 24-year-old from Dublin was known to gardaí for his involvement in organised crime.
The officer leading the investigation said this does not excuse the manner or the motive for his murder.
Mr Finnegan was reported missing from his home at Mary Aikenhead House, Dublin 8, on 10 August.
It is thought he was abducted and killed by criminals.
His body was found partially buried in a shallow hole in the ground covered by undergrowth by people out walking at around 8.45pm on Friday.
An attempt had also been made to set the remains on fire and his clothes were charred.
Mr Finnegan was aware his life was in danger and wore a bullet-proof vest, which was found on his remains.
He was involved in serious crime and had been attacked and shot at a number of times before.
He was charged - but acquitted - of firearms offences after a gun had been found in his home.
Mr Finnegan appears to have been stabbed to death. Gardaí believe he was killed at the scene but have yet to establish if he was abducted or lured there.
They believe his death is linked to organised crime and one line of inquiry is that he was killed in a row over money.
