The father of two brothers killed by loyalists almost 30 years ago has claimed that police have failed to act on new information about the murders.
Gerard Cairns (22) and his brother Rory (18) were shot dead in the living room of their home near Bleary, Co Armagh, in October 1993.
Three suspected agents have been linked to the case, which was featured in a BBC investigation last year.
The programme included an interview with loyalist Laurence Maguire, who was given five life sentences in 1994 after admitting 41 offences including murder and attempted murder.
The men's father, Eamon Cairns, last night said that since the show was aired the PSNI has failed to speak to Maguire, the programme's makers or make contact with the Cairns family.

Maguire claimed he had been involved in a previous attempt to target the Cairns family but the attack, which was planned by former UVF leader and suspected agent Robin Jackson, was aborted.
He also claimed that all targeting information came from ex-UVF commander Billy Wright, also a suspected agent, and was supplied to him by RUC members.
Jackson and Wright, who are both dead, were among nine loyalists arrested after the murders but released without charge.
The family believe another man, Alan Oliver, was one of the killers.
Oliver is now a born-again Christian and has previously been named in court papers as being involved in the murder of three Catholics in Craigavon in 1991.
Mr Cairns last night said: “This new information should have immediately warranted the reopening of a fresh independent investigation by the authorities, yet there has been absolutely no action.
“Shockingly the PSNI has yet to contact the Cairns family, or sought to interview Laurence Maguire, or the programme makers.”
Mr Cairns believes RUC failures to bring those responsible to account “was to protect agents and their handlers”.
He also believes that his family has been “failed by three investigations” involving the RUC, Historical Enquiries Team and the Police Ombudsman.
A spokesman for the PSNI last night said: “PSNI Legacy Investigation Branch has been making enquiries with BBC since earlier this year to obtain the unedited footage to establish the context of the broadcast material and whether there is any other evidence which would enable police to progress investigations.
“This process is ongoing and as such it would not be appropriate to comment further.”
Earlier this year secretary of state Barndon Lewis turned down a request by the Cairns family for a public inquiry into the murders.
They have since launched a judicial review.
Solicitor Fearghál Shiels, of Madden and Finucane Solicitors, said: “Such an inquiry would investigate not only the compelling evidence of state collusion with the mid-Ulster UVF in their murders, but also why his family, including his two murdered sons, have been failed miserably by every single organ of the state which has purported to have properly investigated their murders over a period of almost three decades, yet inexplicably found no evidence of collusion.”
Mark Thompson from Relatives for Justice said issues around collusion need to be scruinised.
