KEY POINTS:
It began as a peaceful event organised by a church group but ended with a teenage boy dying in a pool of blood.
The group was holding a hip-hop event at Avondale College that attracted hundreds of teenagers.
Manaola Kaumeafaiva, 14, was standing by the front gates of the college when he was stabbed in the chest - near the heart - and died soon after.
Police allege another teenage boy, Petani Fa'avae, murdered him and attacked others that night after driving to the event from south Auckland.
Fa'avae's High Court trial began yesterday and is expected to take three weeks. He is charged with murdering Manaola, wounding with intent to cause grievous bodily harm to another young man and three counts of assault with a weapon.
Crown prosecutor Claire Ryan told the jury that on October 22, 2006, Fa'avae, whose name suppression was lifted at the start of the trial, had been drinking with friends when a girlfriend texted them and told them about the event at Avondale College.
Ms Ryan said Fa'avae and three others drove there in a white Honda with a golf club in the back of the car.
The court heard Fa'avae approached Manaola and unflicked the blade of his knife and stabbed him "with some force" in the chest.
As Manaola lay dying, Fa'avae chased another man and allegedly stabbed him on the forearm.
The three other assault charges relate to threats of violence Fa'avae was alleged to have made to others that night.
Fa'avae's lawyer, Jim Boyack, said it was the defence case that Fa'avae was guilty of manslaughter but not murder.
