A man who knifed a dad-of-four through the heart after he complained about a noisy house party has been jailed for life.

Adam Lundy, 28, murdered John Kiltie outside a house in Girvan, South Ayrshire, on May 28, 2016.

Bus driver Mr Kiltie, who was stabbed four times, collapsed and died in his mother Georgina Kiltie's arms after saying: "Help me, mum."

This is the second time that Lundy has stood trial for the 44-year-old's murder.

He was convicted in December 2016, given a life sentence and ordered to serve at least 19 years in prison.

But the conviction was quashed by the appeal court and a re-trial was ordered.

At the High Court in Glasgow, judge Lady Stacey told Lundy: "You took the life of a man who was a well-loved son, partner, brother and father.

"You did so in the course of a violent attack which a knife, following a disturbance started and caused by you and your friends.

"In doing so you have left his family broken-hearted, life will never be the same again for them."

The judge said Mr Kiltie's youngest child is "too young to remember him".

Prosecutor Iain McSporran previously read out parts of impact statements provided by Mr Kiltie's family for the judge to consider.

He said: "Mr Kiltie's father John senior said his son's murder 'destroyed everyone in the family'.

"He said he is sad that his son's youngest child will never know his father.

"He says his son was a good father and that his family meant the world to him and he to them."

The court was told that Mr Kiltie's mother is 'broken hearted and unable to cope' and describes herself as 'a broken woman'.

Mr Kiltie's partner Sharon Tweedie said in a letter to the judge: "He was my best friend and partner for 23 years who was always there for me and the children. I don't think the pain will ever go away."

The court heard Mr Kiltie was targeted after phoning the police about a noisy party in Park Road, Girvan.

He had lived in the street with his partner, 39-year-old Ms Tweedie, for 20 years.

The couple were concerned there was a four-year old child in the party flat and called the police who left after finding no child in the property.

A woman who lived at the house then began shouting and swearing at Mr Kiltie and accused him of being a "police grass".

She also shouted "go and do him in".

Minutes later Mr Kiltie was stabbed in the rear garden of the house.

In evidence, Lundy revealed that before going out into the garden he put a kitchen knife down the back of his trousers.

Mr McSporran asked: "Why did you take a knife from the kitchen?"

Lundy replied: "I just panicked. It was the worst thing I've even done. I just wanted to scare him."

At the time of the murder, Lundy was out on bail for possession of a knife and carrying out racially aggravated assaults on two people. He has previous convictions for violence and carrying a knife.
