GARDAI have confirmed that a search for a murder suspect at a house in Donegal has ended without finding him.
Armed Garda officers, who are providing assistance to detectives from the Police Service of Northern Ireland (PSNI) investigating the shooting of 35-year-old Barry McCrory, had been conducting intensive search operations in the Burnfoot area overnight.
Yesterday the PSNI had warned the public about a suspect they want to interview - 58-year-old Kieran McLaughlin.
A property near the village of Burnfoot was surrounded for much of the night, and subsequently searched.
However, nobody was found inside the house and no arrests were made.
Garda roadblocks in the area have now been lifted.
But the search will continue.
Burnfoot is only a short distance from Derry, around five miles (8 km) across the Irish border.
Mr McCrory was gunned down in a flat in Derry city centre on Thursday morning.
His partner, who was in the Shipquay Street property at the time, was bundled into another room by the killer before the fatal shots were fired.
It is understood the incident related to a fallout over alleged criminality.
Mr McCrory had been known to police for previous offending.
The murder took place less than 24 hours after the body of a father-of-four was found in a lake in north Belfast.
It is understood Kevin Kearney, 46, was shot dead by dissident republicans. A 39-year-old man has been arrested in connection with the shooting.
Officers are not linking the two murders at this stage.
