Four teenagers and a 45-year-old man murdered two boys with machetes in a case of mistaken identity.
Mason Rist, 15, and Max Dixon, 16, died from stab wounds after being chased by four armed teenagers on January 27 this year in the Knowle West area of Bristol.
Riley Tolliver, 18, a 16-year-old boy, a 17-year-old boy and getaway driver Antony Snook, 45, were found guilty of murder.
A 15-year-old boy was also found guilty of the murder of Max after previously pleading guilty to the murder of Mason.
Tolliver, and the three boys, who cannot be named for legal reasons, had been driven to and from Knowle West by Antony Snook, 45, as part of a revenge mission.
The two boys had been wrongly identified as being responsible for bricks being thrown at a house in the rival Hartcliffe district earlier that evening.
Around an hour after that attack, Snook left the property with two of the boys and picked up the other two in a nearby street before heading to Knowle West.

Mason Rist with his grandmother, Gail (Picture: Avon and Somerset Police/PA Wire)The Audi Q2 was driven around Knowle West for at least 12 minutes before the attack, the jury was told.
Snook drove down Ilminster Avenue and when they saw Mason and Max in the street they wrongly believed they had spotted those responsible for the attack.
Ray Tully KC, prosecuting, told the jury: They were entirely wrong about that. Max and Mason had absolutely nothing to do with any earlier incident and no connection whatsoever with those events.
Tolliver, who had a baseball bat, and the three teenagers armed with machetes jumped out of the car and chased after the two boys.

Max and Mason are seen going to different sides of the street, each pursued by two people from the vehicle.
Tolliver and the 15-year-old boy attacked Mason, while the 16-year-old boy and 17-year-old boy chased Max.
The 17-year-old boy also struck Mason, who was lying injured on the ground, as he headed back to the Audi after attacking Max.

A CCTV camera on Masons nearby house captured how the attack lasted just 33 seconds from the car pulling up to the teenagers getting back in and leaving.
Mason and Max sustained fatal stab injuries, and both died in hospital in the early hours of January 28.
Snook drove the teenagers from the scene and dropped them off in Knowle West.
A fire was lit in a back garden and items linked to the attack disposed of.
Meanwhile, the 16-year-old boy picked up a McDonalds meal and drinks just six hours after the attack.
Giving evidence, Snook claimed he thought he was driving the teenagers in his Audi Q2 disability car to a safe house after the attack on the Hartcliffe property.
When he was told to stop in Ilminster Avenue he believed they were outside the safe house, Snook alleged.
Antony Snook, 45, drove the teenagers to and from the scene of the attack (Picture: Avon and Somerset Police/PA Wire)The landscape gardener, who lost a leg in a road accident, insisted he did not know the boys were carrying weapons and was looking in his rear view mirror at the time Max and Mason were attacked.
I thought they had got into a fight or something. I didnt want to be involved with it. I didnt think it was something that cost two people their lives, he said.
I just thought it was something stupid between Hartcliffe and Knowle that I had been dragged into. I didnt realise anyone had been seriously hurt.
The four teenagers did not give evidence during the trial.
But the jury was told the 16-year-old had been covertly recorded in custody saying he had heard Mason screaming during the attack and had to sort of join in.
He also said he had put on loads more tracksuits and left his phone behind before heading to Knowle West.
Riley Tolliver went on a revenge mission to attack the two boys (Picture: Avon and Somerset Police/PA Wire)In closing speeches to the jury, barristers representing the teenagers said there was no joint plan to attack the two boys.
Anna Vigars KC, representing the 16-year-old, suggested her client did not have any intention to kill or cause really serious harm to Max or Mason.
He didnt spring into action he gets left behind. He didnt know what the plan was, if there was a plan, Mrs Vigars said.
It isnt just that his heart was not in it, but his intention was not either.
Christopher Quinlan KC, representing the 17-year-old, said his client had admitted the manslaughter of Max but denied inflicting any injury to Mason.
The jury were shown the CCTV footage of Mason, after being struck by the 15-year-old, getting to his feet, with prosecutors then alleging the 17-year-old inflicted a second blow to him.
But Mr Quinlan suggested an alternative, telling jurors: He had managed to get to his feet but because of the injury he sustained he wasnt able to stand, as the 17-year-old passes him.
We say when you divorce Masons movements from the 17-year-old then the evidence is not there that he did stab him or make contact with him.
Ignatius Hughes KC, representing Riley Tolliver, said his client had not struck Mason with a sword, machete or zombie knife.
A baseball bat is a very different choice of weapon to go out with than a great big zombie knife, he said.
He had an opportunity to cause really serious injury to Mason, but he didnt do it.
Kate Brunner KC, representing the 15-year-old, said he was not involved in the fatal attack on Max because it happened at the same time he was murdering Mason.
He has told you the terrible thing that he did. He was 14 when he stabbed Mason, she added.
He says that he did that, hes been honest with this court and with you by saying guilty.
