A Sebright man has been found guilty on all four charges by a jury for his part in a 2014 crash that killed Shania Slater.

The jury found Andrew Fallows guilty of impaired driving causing death, criminal negligence causing death, impaired driving and dangerous operation causing death.

The verdict came down only a few hours after the jury was charged by a Barrie judge.

“It has been two and half, three years for this moment. It's a bitter sweet moment, but justice is done and we are happy about that,” says Rose Looyenga, Shania’s mother.

While charging the jury, the judge said this case hinges on one question. Was Andrew Fallows driving the truck at the time of the crash that killed 18-year-old Slater?

In his instructions, the judge said “It is not enough that you think Andrew was probably or likely the driver,” telling them that they had to be sure “beyond a reasonable doubt."

The crash happened back in 2014 in Oro-Medonte, along Highway 11 early in the morning.

DNA evidence showed Fallows' blood on the steering wheel airbag and cracked windshield. Slater's blood and hair on the passenger side.

The court heard Fallows' blood alcohol level was three times the legal limit.

“It was definitely hard to hear what he did. I don't understand how anyone could possibly do that. Maybe he panicked, I don't know, I just found that disgusting,” said Melissa Slater, Shania’s sister.

During the trial, witnesses testified how Fallows had waivered in his account of what happened.

In one interview, he told police he was behind the wheel, but then changed his story, throwing the blame on a third person.

The defence has argued, "Fallows cannot be accepted as a reliable historian of the facts because of a head injury and memory loss."

When reviewing the evidence, the judge reminded the jury of the police canine search that was done.

Police testified they scoured the area looking for another person who may have been involved in the crash and “that no third person was found."

The Crown argued throughout the trial Fallows tried to make it look like he was innocent by sliding into the passenger seat.  

Their position has always been that it's "as plain as the nose on your face, Andrew Fallows was the driver."

Fallows will be sentenced on Oct. 10.
