Detectives have made an renewed appeal for information, a week on from the murder of Co Down father of two Wayne Boylan.
Mr Boylan (37) died after being shot in the head by two masked men who burst into his home on the Lower Dromore Road of Warrenpoint on Friday, January 18.
He died at the scene of the attack which is believed to have been drug-related.
A 21-year-old woman, Alice Louise Burns, was critically injured.
She remains in the intensive care unit of the Royal Victoria Hospital where her condition has stabilised but remains serious.
She suffered life changing injuries to her face and neck in the attack.
Police have dismissed speculation that a third man, who was in the property at the time, was the intended target.
Mr Boylan was known to police.
The getaway car used by the killers was later recovered in Dublin, detectives say they have contacted An Garda Síochána who are assisting with the murder investigation.
The PSNI's Major Investigation Team made a fresh appeal for information yesterday, a week on from the murder.
Detective Chief Inspector Eamonn Corrigan said: "We are now one week into the investigation of Wayne's murder and I am keen to hear from anyone who was in the Lower Dromore Road area between 6pm and 8pm last Friday.
"Even if you think you have no information, you may have witnessed something important without realising.
"I am aware of at least one person jogging in the area at the time and I am particularly interested in speaking with this person.
"Wayne was a father to two young children who have now been left without their Dad.
"He was a son, a brother and a friend. On Wednesday Wayne was buried by his family who have been left completely devastated by his murder. They deserve to have answers, they deserve to see his killers put behind bars.
"Were you driving in that area at that time and have dash-cam footage which could be of use to our investigation?
"Did you see two men acting suspiciously or notice any vehicles driving erratically in the area of Lower Dromore Road or the dual carriageway between Newry and Warrenpoint around 7.30pm?
"Please tell us what you saw.
"I would appeal to anyone with information to contact detectives in the Major Investigation Team detectives by calling 101, quoting reference 1115 18/01/19.
"Alternatively, information can also be provided to the independent charity Crimestoppers on 0800 555 111 which is 100% anonymous and gives people the power to speak up and stop crime".
