Police are on the hunt for two people who left a 15-year-old boy to die at the scene of a crash outside Parliament House in Canberra.
The driver responsible for a deadly crash in the New South Wales Hunter Valley region will be sentenced in three months.
Brett Button will face the sentence hearing on September 9 with the court having set aside three days.
35 victim impact statements are expected to be read out during the proceedings.
The 59-year-old was driving a wedding bus in June last year when it crashed, killing 10 people and injuring 25 more.
The 15-year-old boy died after being ejected from a stolen white Toyota Camry which crashed in the early hours of April 17.
Emergency services rushed to Adelaide Avenue, outside Parliament House, where they discovered the car flipped onto its roof.

The car had left the road and collided with a concrete barrier.
The 15-year-old boy was found between five and 10 metres from the wreck, surrounded by debris, and with critical injuries.
Police quickly determined he had been ejected from inside the car.
ACT Policing Acting Inspector Mark Richardson stated at the time speed was “clearly” a factor, and the car was “absolutely destroyed.”

The Major Collision Team from ACT, through extensive investigations, have determined that three people were inside the car when it crashed.
The other two people climbed out of the car before fleeing in a separate vehicle.
Detective Sergeant Jonathon Turkich from ACT Policing’s Major Collision Team said police are urging the two people who left the scene to come forward.
“To a certain extent, it is understandable that people panic in traumatic situations like this, however I cannot understand how you leave any human being, let alone someone you likely know, on the side of the road critically injured,” Detective Sergeant Turkich said in a statement on Thursday.
“This must be weighing very heavily on the conscience of these two people.

“I would implore them to be brave now and approach police so we can bring some answers to the family and friends of the young man who lost his life.
“It may provide you with the opportunity for some relief and support yourself rather than feeling like you’re looking over your shoulder for the rest of your life.”
Investigators are also asking anyone who has information about the two other occupants, or the second vehicle which arrived at the collision scene to come forward.
