'I think that it's a joke' - victim's aunty slams High Court verdict that left boy racer on streets after fatal crash

The aunty of one of the victims of an illegal street race that resulted in the deaths of four people near Hamilton on June 24, 2016 has slammed a High Court judge's verdict.

Justice Anne Hinton sentenced Dylan Cossey to 12 months home detention and 400 hours community service after he was convicted of four counts of manslaughter.

She also disqualified him from driving for sevens years.

The 21-year old was racing a Nissan Skyline at estimated speeds of up to 150km/h through the Waikato when the other car collided with a van near the Hamilton Airport.

Lance Tyrone Robinson, 28, Hannah Leis Strickett-Craze, 24, Paul de Silva, 20, and Jason McCormick, 19, all died in the crash, while the van's driver Matthew Scheepers was seriously injured.

However Mr de Silva's aunty Amber was left extremely upset by the verdict handed down.

"I think that it's a joke as Cossey's behaviour has never shown any remorse or regard for the events.

"He's treated this whole court case like an inconvenience, and the judge has not given an appropriate sentence, as it doesn't take a hard line towards street racing.''

Mrs de Silva felt the decision by Cossey, and his passenger Stephen Jones, to flee the scene was unacceptable.

"Any human being should have stopped to ascertain injury to make sure everything was alright but no. Gap it bro, what winners!"

Detective Inspector Daryl Smith, who was part of the investigation, issued a warning to those considering engaging in boy racing.

"This was a tragedy that could have been avoided had these individuals not engaged in street racing that day, which resulted in a number of families been impacted.

"It's dangerous, anti social and we won't tolerate it."

Jones, 20, who was found guilty of failing to stop and attempting to pervert the course of justice, had his sentencing adjourned until May 3.
