Natasha Warren released early from drunk driving sentence

The family of a 22-year-old Surrey woman killed by a drunk driver four years ago is angry the woman behind the wheel has been released after serving two-thirds of her three-and-a-half year sentence. 

Natasha Warren hit and killed Kassandra Kaulius in 2011 after running a red light at more than a 100 kilometres an hour. 

Kaulius was stopped at a red light when a van driven by Warren smashed into her. Warren fled the scene and tried to hide in a nearby ditch, but she was later arrested and pleaded guilty to three charges including impaired driving causing death. 

The victim's mother, Markita Kaulius, says Warren's release came too soon.  

"It really is not enough considering the severity of the crime," she said. "It's something we don't get over and I don't know if we ever will." 

"My daughter's life was taken by this woman. These were vehicular homicides ... unfortunately our justice system, the way it is, does not classify this as a homicide."

​Kaulius is also uncomfortable, because she says Warren will be living about 20 minutes away from her.

"I hope I don't run into her ... I wish her well. I hope she turns her life around, but everyday is still a struggle."

Warren is not allowed to own or drive a vehicle for six years as part of the conditions of her release. 

During the trial, the Crown said Warren had consumed a bottle-and-a-half of wine that night and blew twice the legal limit of .08 blood alcohol level when tested by police.

Kassandra​'s parents have been fighting for tougher drunk driving laws since their daughter was killed. Markita wants convicted drunk drivers, such as Warren, to spend a minimum of five years behind bars.

According to parole board documents, Warren completed substance abuse programs while behind bars and the parole board found her to be at a low risk of re-offending.
