Both men identified, with one found dead with stab injuries and the other hit by a car soon after alarm was raised
Gardaí are following a "strong line of enquiry" that the two deaths that happened in Co Monaghan this morning may be connected.
One man in his 60s is believed to have suffered a violent death in a house in Broomfield.
His body has been taken to Our Lady of Lourdes Hospital in Drogheda for a post mortem examination.
His body was discovered by a family member who called to the property at about 6.30am.
A short distance away, a second man was pronounced dead after he was struck by a car on the Ballynacarry Bridge, the N53 Dundalk Road - also this morning.
The crash occurred at about 7am, about 3km from the house where the other body was found.
The man who died after being hit by the car was in his late 30s and has had an address in south Armagh.
The two men have been identified and officers are working to establish the nature of their relationship.
Local Fine Gael councillor Aidan Campbell is calling on any locals who have information to pass that on to Gardaí:
