The parents of a 22-year-old softball player killed in a collision with an alleged drunk driver in Surrey are pleading for changes to B.C.'s impaired driving laws.

Kassandra Kaulius was on her way home from a softball game on Tuesday night when her BMW was broadsided by a van that had allegedly blown through a red light. She was pronounced dead at the scene.

Police believe that the 34-year-old woman driving the van was drunk at the time, and she could face a charge of impaired driving causing death.

Kassandra's parents Markita and Victor Kaulius are outraged about the death of their "caring, loving" daughter.

"This woman, she didn't have a knife or gun, but she still murdered our daughter," Markita Kaulius told CTV News.

"The laws need to be changed, and that will be our mission now, to work with other families who've had to deal with this, and I really think that people need to say, enough is enough."

Kassandra's boyfriend Cody Schlamb says his future has been shattered by the death.

"I did lose my future wife, the future mother of my children, the person who I planned to grow old with" he said.

He planned to propose to her in August, but instead is now wearing her promise ring on a chain around his neck.

The suspect has been released from custody and won't make a court appearance until the fall. She was driving a company vehicle from Precision Restoration in Delta at the time of the crash; the company says she has been fired.

A scholarship fund has been set up in Kaulius's name at Coast Capital Savings. Anyone interested in donating can ask for the Kassandra Kaulius Surrey Storm Scholarship at any branch.
