Louth gardaí investigating the murder of Dublin man Mr Lee Conkey (30) last weekend have not had a single response to their appeal for information.The investigation is being led by Supt Fergus Doggett, who said it was possibly "sinister" that the appeal had fallen on deaf ears.
"We have not had a single phone call; it may be the weekend that was in it, and I am now renewing that appeal.
"Someone, somewhere knew where he was going and who he was going to meet, and the Garda still want to talk to those people. They can contact gardaí in Drogheda or the Garda confidential telephone line on 1800 666 111."
Gardaí are also mystified as to the motive for the murder as the method of death - strangulation - means that his links to the INLA may not be directly related to his death.
"In the past people who have been murdered by the INLA have been shot or been the victim of a particularly violent assault using weapons such as machetes; that makes this crime more of a mystery," said one Garda source.
Supt Doggett confirmed gardaí had not ruled out "that it could have been related to something that has nothing to do with groups such as the INLA or loyalists".
Mr Conkey was last seen alive at 10 a.m on Friday, when he left his home in Dublin's St Teresa's Gardens to meet somebody.
He was a keen motorcyclist and left his home on a Yamaha bike worth around €14,000, registration number 03 D 56939. Neither it nor his helmet have been found.
Gardaí do not know where he was murdered, but given the dead man's physique believe a number of men would have to have been involved in the death and also transporting the body to Togher.
He was 5ft 10ins and weighed close to 14st. When his body was found lying face-down in a dyke or ditch just off the Togher to Annagassan road it was dressed only in biker-style leather trousers.
His body would have to have been taken there in a large vehicle, possibly a van, and they believe this was done sometime late on Friday night or in the early hours of Saturday morning.
On Saturday evening Supt Doggett made his first appeal to the public to come forward with any information on the crime or if people had seen anything suspicious. Yesterday he renewed the appeal.
It's understood Mr Conkey was claiming social welfare benefit, but had in the past worked as a bouncer in Dublin. He and his family had to flee Northern Ireland in 1997 after being petrol-bombed by loyalist paramilitaries and he was known to gardaí because of his alleged associations with the INLA.
