The family of a councillor murdered 35 years ago have withdrawn their co-operation from an investigation into the death.
Relatives of Patrick Kelly, 33, from Trillick, Co Tyrone, whose body was found in a lough after he was abducted and shot, said they no longer had any confidence in the Historical Enquiries team.
"The approach has been one of window-dressing, using fine sounding words and carefully crafted statements which when examined, are all but meaningless," a statement said.
The body of Mr Kelly, a Catholic father-of-three, and a nationalist member of Omagh District Council, was found tied to two 56lb weights in Lough Eyes, near Tempo about 10 miles from his home in August 1974.
He went missing just over a fortnight earlier on his way home from a pub in Trillick which he managed.
Even though loyalist paramilitaries claimed they were responsible, it is widely believed that members of the Ulster Defence Regiment who had been operating a roadblock near the house at the time may have been involved.
David Jordan, a former UDR man who died in suspicious circumstances in October 1999 claimed he had detailed knowledge of the murder. He was never questioned and no-one ever charged.
The Historical Enquiries team began their probe in early 2007, but the Kelly family confirmed on Monday they had lost all trust in the investigation and called for a full independent inquiry into the death, including allegations of collusion by the security forces.
