THE killer or killers of a takeaway delivery driver acted as judge, jury and executioner, a priest at his Belfast funeral said.
Last Monday night's shooting of Dan Murray (55) was the fourth gun attack in the city in four days.
The victim was lured to his death by a bogus fast food order, detectives said.
Mr Murray, who was known to police and had survived a previous murder bid, had been dispatched in his black Ford Focus to deliver food to a house in the Lady Street area of West Belfast.
Fr Brendan Smyth told mourners at the Holy Trinity Parish Church on Monday: "Danny's death was a horrific one, where his life was snuffed out in the blink of an eye, from behind him his killer set themselves up as judge, jury and executioner."
The father-of-six was shot in the head when he drove into Lady Street.
Fr Smyth said the gunman had no concern for the victim's children or the impact this murder would have upon them.
"They have been added to the very long list of those who suffer at the hands of those who have no care for justice, those who seek to settle things by the barrel of a gun.
"And they say we live in a more civilised and peaceful time in our city's, our country's history, I think not."
He said the murderer or murderers believed life was "worthless".
"This is the second time in as many months that I have had to stand at the door of this church and received the remains of someone who was murdered.
He feared for the impact on worshippers.
"They too must be affected by how violent this city has become. The consequences of Danny's death will therefore ripple out for a long time to come.
"How long must we wait before the lessons are learnt, that whatsoever you do to the least of these my brothers and sisters you do to me?"
He said they faced eternal punishment.
"Those who took Danny's life, and all who are involved in leading others down the path of self-destruction, may well have no care or thought that what they do, they do to Jesus. Well they would do well to listen to the end of the Gospel."
He added: "The words of the Gospel are clear and concise, without confusion, 'and these will go off to eternal punishment'."
