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.
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.
