Teen testifies of joyride on night Const. Garrett Styles died

A Newmarket, Ont., court on Tuesday heard riveting testimony on a how the thrill of a joyride turned into a "dark and silent" night with a York Regional Police officer dead and a young man paralyzed.

"Never in a million years did I want what happened that night to have happened," said the teenager accused of first-degree murder in the death of Const. Garrett Styles.

"Officer Styles is dead, I'm paralyzed for the rest of my life.  I always think that it should have been the other way around," he said, speaking softly.

The now 19-year-old accused told the court he wakes up every morning thinking about what happened in the early-morning hours of June 28, 2011.

Stopped for speeding

The jury heard how the teenager — who is being tried in court as a youth and cannot be named — was 15 at the time and behind the wheel of his parents' Dodge Caravan when Styles stopped the vehicle for speeding.

The teenager, who was continuing his testimony that began Monday, testified that in the course of being stopped on Highway 48, Styles reached into the van and grabbed the steering wheel.

The young man then showed the jury a scar on his arm. The defence said it was bite mark left by the officer. 

The teenager said he doesn't know what happened after that because he said he closed his eyes when the car started moving.

'Everything went dark and silent'

"When I did open them, I was hanging off the side of the seat. Everything went dark and silent... I had no idea where Constable Styles was," he said.

"I was just terrified I couldn't move."

The vehicle had turned over in a ditch, onto the 32-year-old officer, who died on the way to hospital.

Court heard how, five months before he was stopped by Styles, the young man had been charged with driving without a licence.

Police at the time escorted the teenager home where he promised his parents he would never take the car again.

But, as he told the court on Tuesday, he continued to drive his friends around.

"You really had to love taking those chances, those risks, Crown attorney Rob Scott said to him.

"It was more important to have fun than to obey your parents," said Scott.

"Unfortunately, yeah," the teenager replied.

The crown will continue its cross-examination on Wednesday.
