The fatal shooting of a man at a house in Co Down has been described by police as a "senseless and callous murder".
Wayne Boylan, 37, was killed on Friday evening when two masked men burst into his friend's home on the Lower Dromore Road, Warrenpoint and opened fire.
Pellets from the blasts also struck a 21-year-old woman in the face and neck.
She remains in a critical condition in hospital after undergoing emergency surgery.
Detective Chief Inspector Geoff Boyce said there remains"no clear motive" for the attack on the father-of-two.
Mr Boylan had been at his friend’s house when the men entered the property at around 7.30pm.
"The pair, who were masked, fired at Wayne with what police believe to be a shotgun, striking him in the head and fatally injuring him," he said.
Mr Boylan died at the scene.
Mr Boyce said it was a "senseless and callous murder perpetrated on a completely unsuspecting man".
"Wayne was a father and his two young children have been left without their father," he said.
"He was a son, a brother and a friend.
"His murder has caused his family and friends immeasurable pain and their lives will be forever changed by his loss."
Police made a direct appeal to anyone who has any information about the murder.
"We want to be able to give answers to a grieving family. To give them justice by putting his murderers behind bars."
