Gardaí, investigating the murder of Andrew Burns, are making a renewed appeal ahead of the 15th anniversary of his death.
He was 27 years old when he was shot and left for dead on a roadway close to Donnyloop Church near Castlefin on the Donegal/Tyrone border.
Gardaí are particularly interested in speaking to the occupants of a red car, which is believed to have been in the church carpark on the evening of his murder.
Anyone with any information - regardless of how insignificant it may seem - is urged to come forward.
