The family of a man killed on the border 30 years ago are to ask police in the Republic to re-open an investigation into his murder.
Relatives of Paddy Cunningham (32), whose body was discovered buried at a derelict house at Errybane near Castleblayney in 1987, have announced they are seeking a "full probe" into the murder.
It was initially claimed that Cunningham, who was abducted from a house at Ballybay in Co Monaghan, was a victim of the INLA. However, an INLA spokesman later denied the group had any involvement.
A spokesman for the family, which extends between Castleblayney in Co Monaghan and Keady in south Armagh, said: "We are anxious to see the perpetrator, or perpetrators, of Paddy's murder brought to justice. There is grave dissatisfaction over the fact that there appears to have been little or no follow-up to vital forensic evidence, and other factors, which emerged at the time.
"It appeared he was murdered in May 1987, but his body wasn't discovered until six months later, in December of that year.
"We believe crucial forensic evidence, which was found at the house where he was covertly buried, could have led to a successful conclusion of the murder investigation and a conviction, but it seems this was missed by the authorities at the time."
The spokesman said that having discussed the case with legal representatives for the family, they are still hopeful of a renewed probe by the garda.
He added: "Thirty years on, we are saddened to say that, up to now, we have felt let down by An Garda Siochana."
A garda spokesman has declined to make any comment on the case.
