One of the two young defendants accused of killing 18-year-old Connor Boyd in central Auckland had attacked another teen the same night, a court has been told.

It was the second time the female defendant had targeted the teen at the same nightclub in less than a week.

“I felt a yank, like a grab, on the back of my head,” victim Ella Olson told jurors in the High Court at Auckland today, explaining that she didn’t see the defendant when she was pulled to the ground by her hair, bruising her tailbone. “I felt like I couldn’t move ... and once I looked up straight I could see it was her.

“Her leg was stomping me around my stomach and my chest area.”

The two defendants, whose names are suppressed, are facing trial for the alleged manslaughter of Connor Boyd, who died after being run over when his attackers grabbed him by the arm as they drove away. Defence lawyers have described his death as a “tragic accident” unworthy of a criminal charge.

But the female defendant also faces a series of assault charges relating to her interactions with Olson that night. She has pleaded guilty to pulling Olson backwards by the hair but denies having stomped on her during the same attack. She also denies having kicked Olson in the face a short time later as Olson was crying on the phone to her mother, sitting on a kerb outside the club and waiting for a ride home.

The defendants, who were both 18 at the time of the April 2022 incidents, have also pleaded guilty to attacking Boyd that night in an incident outside the nightclub before his death.

Prosecutor Claire Paterson told jurors at the outset of the trial yesterday that Boyd’s death was the result of “pointless teen drama” and “immature teen relationships” that had become a “festering sore point” for the female defendant, causing her to act aggressively.

Olson had been in a brief relationship with a mutual friend who had recently ended a long-term relationship with another woman. The defendant, who was friends with the ex-girlfriend, had begun harassing Olson over the phone to the point where Olson blocked her number.

Connor Boyd died outside Saturdays nightclub in Britomart, central Auckland.

It came to a head on a Wednesday night inside popular Britomart nightclub Saturdays, when Olson and both defendants showed up separately.

Seeing Olson, the female defendant called her a “whore” and a “homewrecker” before pouring a drink over Olson’s head, then grabbing Olson’s drink and throwing it at her, Olson recalled today. The two exchanged punches and were escorted out of the club, CCTV footage shows.

Olson said she thought the “beef” was over because the defendant had got it out of her system. But then she ran into the defendant at the same nightclub several days later, just past midnight on Sunday, April 24 last year.

After noticing the defendant, Olson said she was trying to avoid her when her hair was pulled from behind.

Although the hair pull was clearly seen on CCTV, the crowd was so thick that jurors couldn’t see what happened once Olson fell to the ground. Defence lawyer Julie-Anne Kincade suggested repeatedly that the stomps never occurred and that her client instead bent over to pick up her dropped phone.

Olson insisted she remembered the attack correctly and that it involved stomping.

She conceded, however, that the second attack that night involved a kick to her cheek that “wasn’t super forceful so it didn’t hurt as badly”. Kincade suggested the kick didn’t occur at all.

Sometime after the second attack that night, while still waiting for her mother, Olson said she ran into Boyd, a mutual friend of hers and the defendants.

“He saw I was upset and asked what happened,” she recalled. “I told him that [the female defendant] had hit me and I was going home. I asked if he would wait with me.

“He was just comforting me and telling me that everything would be OK.”

At some point while the two were standing together, the male defendant walked up. Although she wasn’t listening to all that was said, she recalled Boyd and the male defendant exchanging words “like they were having a disagreement ... but not a full-blown argument”. Boyd, she said, was a calm person by nature and didn’t seem especially riled by it.

A short time later, her mother, Sasha Olson, arrived and the witness and several of her friends got in the car.

Sasha Olson, testifying next, recalled receiving a call that night from her daughter “crying hysterically”.

“Mum, she’s done it to me again,” she recalled her daughter saying.

She was hurriedly getting dressed to pick up her daughter when she heard a scuffle on the other end of the line, she said.

As she was slowly driving away from the nightclub with a car full of teenage girls, she recalled seeing Boyd on the walkway.

“He just wandered over. He seemed absolutely fine,” she recalled. “He seemed calm – his normal, smiley self.”

She thanked him for waiting with her daughter earlier.

“I said to him I thought he was an amazing boy, that I loved him and how he looked after Ella,” she testified. “He said, ‘I’d do anything for Ella.’”

As they were talking, the SUV with the defendants pulled up across the street and stopped, she said.

“I was quite angry. I had a lot of adrenaline coursing through me,” the mother said. “I’m not proud but I remember calling out the window, ‘You f...ing little bitch, we’re definitely going to the police this time.’”

Connor Boyd, 18, died in April 2022 after he was run over in central Auckland. Two other teens have been charged with manslaughter.

She offered Boyd a ride but he declined and she didn’t have any worries about his safety.

CCTV shows he was walking towards the SUV as Olson drove off.

Sasha Olson recalled looking back for him and realising she could no longer see him.

“Oh my God, that’s so strange. What the hell?” she recalled thinking.

It was around that time, prosecutors allege, that the defendants grabbed Boyd’s arm and drove off, causing him to run alongside the vehicle in an effort to keep up before he fell and was fatally run over.

The defence, however, has suggested Boyd wasn’t being dragged when he fell but was throwing punches inside the window of the vehicle. The male defendant was acting in self-defence when he drove away, defence lawyer Paul Borich KC has said.

During cross-examination of the mother today, he pointed repeatedly to her recollection that the SUV had either slowed down or stopped completely at a traffic light. Boyd had ample opportunity to stop throwing punches and leave the vehicle at that point, he has suggested.

Borich also noted that, in the mother’s initial statement to police, Boyd had responded when the mother paid her a compliment: “Ella, I’ve always got your back, you know that. I would fight five guys for you.”

The trial is set to continue this afternoon before Justice Ian Gault and the jury.
