There is no dispute over the identity of the now 14-year-old who wielded it and dealt the fatal wound, but the issue of self-defence looms large.
Yesterday, the High Court at Dunedin viewed further CCTV footage of the incident from an array of angles, often slowed down so the jury could scrutinise every moment of the incident at Dunedin’s bus hub on the afternoon of May 23 last year.
The defendant was captured getting off his bus and walking past Enere before turning round to meet the advancing victim.
After initially stepping backwards, the defendant pulled out a knife and sent the victim into retreat before the stabbing took place.
But there was a dispute between witnesses over the prelude to the violent clash between the teenagers.
Bus driver Christopher Kitto, who had parked outside the Dunedin Central Police Station, said he heard Enere yelling "Come on, come on, let’s go, let’s get at it".
He said the older boy appeared to be "spoiling for a fight".
Mr Kitto said the taller boy appeared undeterred when the defendant put his hand into a shoulder bag before withdrawing a knife.
"Get it out, get it out," Enere said, according to the bus driver.
The defendant ultimately brandished the blade and lunged at the victim, chasing him on to the road, where he stabbed him in the stomach.
The defendant’s counsel, Anne Stevens KC, suggested he had an uninterrupted view of events, better than the cameras — "the best seat in the house".
"I didn’t really want to be, but yes," Mr Kitto said.
But a schoolgirl who was on the scene said the defendant seemed more keen for a physical confrontation.
Earlier this week, the court heard the altercation may have been sparked by Enere making a derogatory comment regarding the defendant’s outfit — a white ski mask, a sideways cap, socks pulled up and a shoulder bag.
The teenage witness, who was walking by with school friends, said she heard the victim say something about the clothing but could not be sure what it was.
When the two squared up, the girl, who has name suppression, said they were each saying: "Do you wanna go" — "go, as in fight", she clarified.
It was the defendant who seemed most "agitated" and repeated the challenge more frequently, the girl said.
She saw the boy run "full force" at Enere and start swinging at him before losing sight of the duo as she walked into the neighbouring supermarket carpark.
The boys were quickly separated in the middle of Great King St and the victim could be seen lifting his clothing to examine the damage to his midriff.
One of the first people on the scene, who knew both parties, helped break up the fight.
"As I was running towards the bus, a knife came towards me and dropped on to the ground," he said.
CCTV showed him stopping briefly and throwing it over towards the public toilet block.
The 31cm, black-handled kitchen knife, inside a plastic box, was produced as an exhibit and the witness confirmed it appeared to be the one he had found.
He described pulling the defendant away from the melee, but said his attention quickly turned to Enere when he noticed a deep stab wound in his abdomen.
Enere was rushed to hospital, but died shortly after.
The trial is scheduled to run for another three weeks.
