The five defendants attacked two young men, aged 15 and 16, in January this year. The victims were wrongly identified by the attackers.
Four teenagers and an adult were convicted in court in England on Friday of stabbing two boys to death in a case of mistaken identity.
The victims, Mason Rist, aged 15, and Max Dixon, aged 16, were chased and attacked by four young men as they were supposedly going to get pizza near their home in Bristol on 27 January this year.
During the trial, which took place over five weeks in the same area, it emerged that Mason Rist and Max Dixon were victims of a rivalry between their neighborhood of Knowle West and the neighboring district of Hartcliffe.
The attackers had wrongly identified the young men and believed the pair were responsible for throwing bricks at a house in Hartcliffe on the day of the attack.
The boys were attacked with knives, a baseball bat and a sword in an attack that lasted about a minute. They died hours later in hospital.
Five defendants were found guilty of the crime on Friday and their sentences will be announced later.
Three defendants aged 15, 16 and 17, whose identities have not been revealed due to their age, were convicted along with Riley Tolliver, 18, and the driver who set them off, Antony Snook, 45.
"Regardless of which individuals caused the fatal injuries, the evidence shows that all five (defendants) worked together and share joint responsibility for this appalling crime," said Vicky Cook, the chief crown prosecutor for the south-west of England.
The mother of Max Dixon, one of the victims, stresses that the outcome "does not change the fact that two families will go home without their children. We hope that now we can begin to process this and remember both of them and the happy memories that both families have of Max and Mason."
