The driver who allegedly struck and killed 22-year-old Kassandra Kaulius in her vehicle Tuesday night ran into the woods after the crash, police say.

Police say Kaulius was turning left from 64th Ave onto 152nd Street in Surrey around 10:15 p.m. when her red BMW was broadsided by a van driving northbound in the curb lane.

People at the scene told investigators the driver of the van was speeding when she blew through a red light, striking the driver's side door of the BMW. Kaulius was pronounced dead at the scene.

Police say the 34-year-old driver of the van got out of the vehicle and tried to run away after the crash. She was found by a bystander and apprehended by police a short distance away in a wooded area. She now faces a possible charge of impaired driving causing death.

The bystander, who asked not to be identified, told CTV News he saw the suspect lying motionless and face down in a grassy embankment after fleeing the scene.

"She couldn't get up on her own," he said.

Kaulius's sister Miranda Tracy visited the scene to express her grief.

"From what we've heard it was from a drunk driver. Please don't drink and drive -- look what it does," Tracy said.

"[Kassandra] was a girl that didn't drink, she never did drugs. She was just that all-around perfect girl, and to be taken like this, it's just ridiculous."

Kaulius, a star softball player and coach, was on her way home from a game when she was killed.

The suspect was driving a company vehicle from Precision Restoration in Delta at the time. The company's owner told CTV News that he couldn't provide any information about the case because of privacy laws, but expressed condolences to Kaulius's family.
