Detective Chief Inspector Brian Howie, who led the investigation, said: “Jason’s death tragically illustrates the awful consequences that carrying weapons can bring – a young man’s life has been cut short in its prime and Jason’s family and friends have been left to deal with the pain of this loss.

“In addition, a teenage boy will now spend time in prison as a result of his actions that night.”

Jason’s sister Jessica said: “It’s almost a year since we lost Jason and today’s sentencing will not bring Jason back.

"We have to navigate the rest of our lives knowing that someone took it upon themselves to take him away from us.

"The daily pain we feel as a family, the void and the reality of doing the rest of our lives without Jason is so heart-breaking.

“A violent act has now impacted two families; Jason we will never see on this earth again, all we have is the memories we made together.

"The teenager convicted will get to see his family and live the rest of his life.

"All we can do is hope that he understands the damage he has caused.

“We are so sorry that this happened to you Jason, and we did everything we could do to make sure your death wasn’t in vain.

"We think about you every day, we miss you so much. We love you forever.”
