A murder inquiry is under way after a man and woman were shot dead at a flat in Craigavon, Co Armagh.
The victims' bodies were discovered at an address in the Legahory Court area of the town just after 6pm yesterday.
Police sources played down fears of a dissident republican link to the murder of the couple - initial theories suggest gang criminals may be to blame.
Police have described the killings as 'brutal and callous'.
The couple have been named locally as Hugh McGeough and his partner, Jackie McCartney.
They sustained gunshot wounds to the head.
Police have appealed for anyone who witnessed anything suspicious in the area to come forward.
Mr McGeough was known to police and had been acquitted of the murder of a 19-year-old man in Craigavon in 2001.
Officers from the PSNI's serious crime branch, who are leading the probe, said their inquiries were at an early stage.
Police last night cordoned off a wide area around the flat where the fatal shootings took place.
Local sources said the area had been blighted by drug-related crime.
Sinn Féin representative for the Craigavon area John O'Dowd said the community was stunned by news of the shooting.
‘I share the concern of the local community and the shock of the community at how this couple has met their death,’ said the Assembly member.
Chairman of the area's local district policing partnership Michael McGoldrick said he was shocked by the murders.
‘The discovery of two dead bodies in a house in Legahory in Craigavon has stunned everyone in the local community,’ said the SDLP councillor.
‘News that the police are treating the deaths as murder will compound the sense of shock and disbelief felt by residents in the area.
‘My immediate thoughts and prayers are with the friends and family of the man and woman who have lost their lives.
‘I would appeal to anyone with any information to contact the PSNI immediately.’
