BEAVERTON, Ore. – A 17-year-old International School of Beaverton student unintentionally struck and killed a woman walking her bike after driving out of the Southridge High School parking lot Thursday night.

Beaverton police identified the victim Friday morning as Helen Iva Grochowski, 63.

Beaverton police spokesman Mike Rowe said Grochowski was walking in and out of a bike lane. No one saw the moment she was hit.

The driver saw her in the bike lane just before the impact. He noticed she was wearing dark clothing and carrying an umbrella. He looked left at the traffic light, then heard the sound of his vehicle striking her.

Evidence suggests she left the bike lane and entered the traffic lane, where she was hit, Rowe said.

"There is no evidence that the driver was speeding," Rowe said. "His cell phone was checked, and there was no calls or texts until after the collision. There is no evidence that the driver did anything that directly contributed to this tragedy."
