GARDAI believe that dismembered gangland murder victim Christopher Gaffney's body was cut up in the bath of a suburban home.
Detectives are satisfied they have identified the house where the drug dealer was carved up after examining at least half a dozen bath tubs.
Gaffney was stabbed to death almost two months ago.
The head and one of the feet of the murdered man remain missing as officers continue to build a case against the 37-year-old's killers.
Gardai have examined at least half a dozen bathtubs and associated plumbing at various properties.
A senior source explained: “Reliable information has come in that this unfortunate individual's body was cut apart in a bath after he was killed during the course of a brutal row.
“Why they wanted to cut him up - everyone is at a loss to know. It is possible they were trying to send out some sick message.”
In recent weeks, garda forensic experts spent hours combing a property at the Ashmount estate in Blakestown, west Dublin, where they believe that Gaffney was killed.
Gardai have been working in the theory that the criminal whose mutilated body parts were found in a field in Clonee, Co Meath, was murdered because he was selling heroin to the sister of two west Dublin drug dealers.
It is understood that he was murdered around a month before his arm was found by pheasant hunters.
Detectives investigating the shocking murder are now satisfied that he was murdered in a property in the Blakestown area.
Two brothers from the area are being investigated for the murder - both are mid level drug dealers.
Detectives think it “is highly unlikely” that Gaffney was murdered for his role in the 2010 murder of a young man.
Gaffney was previously arrested by detectives probing the murder of a young man whose body was dumped in a field - but he was not charged in relation to the crime.
Gardai believe that while Gaffney did not kill the young man, he played a major part in disposing of his body.
