"I think she'll just want to talk to Luke and say, 'we'll fight for you, we'll get the justice you deserve'."
"She's lost a bit part of her life and I think she wanted to say she's always there for him ."
Wilson said his sister was still mourning the loss of her son 10 months after his tragic death.
"It feels like a bad dream to her. She's still waiting for him to come back.
"There are no words to describe it - it's been traumatic - and she's still grieving."
The lack of a decision meant the family would have to prepare for reliving the events over again at a second trial.
In the meantime they would be focusing on next month's unveiling of Luke's headstone at the picturesque hilltop burial site.
Wilson said the ceremony would focus on celebrating the talented teen's life.
"He was an outgoing young man with a lot of potential who was on the verge of becoming a superstar in rugby league and we need to celebrate that."
The headstone would feature a special tile adorned with messages in remembrance of Luke penned by close family and friends.
Wilson said his sister wanted to thank everyone who had stood with her whanau throughout last week's trial.
