A killer stabbed his neighbour to death after a row about their homes descended into murder.
Jorgo Pano had a long-running disagreement over "planning permission, driveways and car parking" with Dave Newton and his family.
Violence was sparked when the 44 year-old hurled paint over his fence onto the Newtons' car late at night.
A fight then broke out on the afternoon of March 7 last year in the normally quiet McAllister Avenue in Airdrie, Lanarkshire where the families lived.
Crazed Pano went on to knife Dave, 48, in the neck after rushing into his home to grab a blade.
The dad died three days later in hospital.
Pano - a first offender - insisted what happened had been an "accident".
But, jurors today found him guilty of murder as he was jailed for life and ordered to serve a minimum 16 years behind bars.
A judge at the High Court in Glasgow stated the killing had been a "disaster" for everyone concerned.
Pano moved to the street with his wife Fiona and family around eight years ago.
The trial heard how there had been "disputes" between himself and the Newtons, who lived next door.
His QC Iain McSporran asked Pano: "The falling out over planning permission and car parking and the driveway never got as serious as this, did it?"
He replied: "No, it did not. I am devastated."
In the hours before the tragedy, Pano was clocked lobbing paint at the Newton's motor damaging the vehicle.
Later on the Sunday afternoon, Pano was out doing gardening work when he was confronted by Dave's son-in-law Lee Harris about what happened.
The men started fighting and Pano smacked Lee with a spade. Gravel was also chucked.
Dave and his wife Angela came out to the street. Others neighbours joined to try and calm matters.
Pano went on to spit in Angela's face.
The row seemed to end and Lee headed back to the Newtons.
But, he then spotted Pano racing out his front door brandishing a knife.
Jurors watched the horror which was captured on CCTV.
Lee recalled: "He then ran into the middle of the road in the direction of Dave and the other neighbour Billy McDonald.
"He then swung the knife in a downward motion in an attempt to inflict damage on Dave.
"He missed and Billy was trying to pull him away. The neighbour's wife was out screaming: 'no, stop'.
"The neighbour (Pano) then put the knife in his left hand, swung over the top of Billy's head and hit Dave stabbing him in the neck.
"Dave immediately put his hands there. He got help back to the house.
"I was shouting on neighbours to phone an ambulance."
Prosecutor David Dickson asked the witness: "How did he (Pano) appear when he came out?"
Lee: "In a blind rage. He came out running."
The Newtons' other neighbour Stephen Trainor rushed to Dave's aid.
He told the jury: "I seen Dave on his knees next to the front door. He was in shock, panting for breath, chalk white.
"He seemed traumatised by the whole episode. I was saying: 'It's alright, big man."
Advocate depute Mr Dickson: "Did he speak back to you?"
The witness: "Not a word."
Dave sadly passed away on March 10 at Glasgow's Queen Elizabeth University Hospital.
Pano - who worked as an air condition engineer - accepted at trial he had fatally struck his neighbour.
But, he claimed to have only got a knife as he feared for himself and his then pregnant wife.
This was despite one witness stating Dave was "not a violent man".
Pano said he had fallen forward with the knife in his hand and hit the dad.
His QC Mr McSporran: "Are you saying it happened by accident?"
Pano: "Yes."
As well as murder, Pano was also guilty of assaulting Lee and had previously admitted spitting at Angela.
Members of Dave's family sobbed and hugged each other as the verdicts were announced.
It emerged Angela had penned an emotional victim impact statement to the court on the impact of the death.
No details were read in open court.
But, Mr McSporran said: "I do not think I have read a more moving and eloquent account."
Sentencing, Lord Beckett also praised the "brave and selfless efforts" of other neighbours to try and protect Dave.
The judge told Pano: "The bad relations with your neighbours over many years presents no justification.
"You contributed significantly to the difficulties between the two families.
"You selected the largest knife from your home and charged at him determinedly."
After Pano was lead to the cells, the judge spoke to jurors.
He said: "It is a tragedy that reaches wide in this case. It is just a disaster for all concerned.
"But, that was a situation brought by Mr Pano when he brought out a knife for what had been a pretty low-level incident."
