The family of a Co Tyrone man whose murder involved “collusive behaviour” has marked the 50th anniversary of his sectarian killing.
Omagh District councillor Patsy Kelly is thought to have been killed as he returned home from work at a bar in Trillick, Co Tyrone, on July 24, 1974.
His remains were weighed down before being dumped in Lough Eyes in Co Fermanagh and were recovered three weeks later when they floated to the surface.
He had been shot six times.
The Kelly family and others have long suspected the involvement of UDR members in the murder
While no-one has been convicted, several former members of the UDR have been arrested and questioned.
Ex-DUP assembly member and UDR member Oliver Gibson, who died in 2018, aged 83, was under suspicion of involvement within hours of the killing a but was never charged.
A series of events were held in Co Tyrone over recent days to mark the 50th anniversary.
On Saturday a special Mass was held while hundreds of local people attended the site where the father-of-five was abducted.
They later took part in a memorial walk to nearby Brougher Mountain.
Players from Trillick and Dromore GAA clubs also held a minute’s silence in memory of Mr Kelly before a recent league match.
Mr Kelly’s son, also Patsy, said the community from which his father came “have always demanded justice”.
“They came together to demand an end to the lies, the deceit, the delays and the injustice they have witnessed for five decades,” he said.
“Fifty years on, Patsy Kelly’s community demand truth and justice.
Last year the Police Ombudsman found there was a series of “significant” investigative failings in the case and revealed that RUC Special Branch and a senior officer in the area were aware of “significant intelligence” that a UVF unit was active in Fermanagh at the time of the murder.
A number of this unit’s members were “either directly linked to Mr Kelly’s murder and other terrorist attacks”.
The ombudsman also revealed that a number of security force members, including police officers, “were also linked to this unit and its activities”.
