Gardaí are treating the death of a man whose body was discovered in Churchill, Co Donegal at the weekend as suspicious.

Kieran Callaghan's body was found in a house at a rural location on Sunday.

The scene was being preserved today and technical examinations were carried out at the house.

For operational reasons gardaí said the results of a post mortem carried out on the body will not be made public.

Mr O’Callaghan was initially thought to have died of natural causes, but further examinations led gardaí to believe the 50-year-old’s death was suspicious.

Mr O’Callaghan lived about a kilometre outside the village of Churchill.

He was last seen alive in the Churchill area at 6pm on Friday.

Speaking at Letterkenny Garda Station, Inspector Michael Harrison appealed for anyone who saw Mr Callaghan between last Thursday and Sunday afternoon at 1.30pm to come forward to Milford Garda Station.
