It is understood that the Garda detective shot dead tonight in Ireland during a botched hold-up detective was married with three children.
He lived in the Lordship area near the credit union where he was killed.
Local councillor Jim Loughran knew the detective and described him as a quiet, decent family man.
"I just spoke to him last week on the street in town. I can't believe this has happened," Mr Loughran said.
The Sinn Fein councillor condemned those responsible for the shooting, saying they had devastated a small tight-knit community.
"This was not just an attack on a Garda detective, it was an attack on the whole community," he said.
