TIGARD, Ore. A Tigard man is accused of endangering his two young children by recklessly driving 109 miles an hour along Interstate 5 near Woodburn with them in the car on Sunday.

Police said the kids were in the back seat of the Subaru Impreza when Jeff Bankston sped past Marion County Deputy Ryan Postlewait s unmarked patrol car on I-5. The 5-year-old boy was not wearing a seat belt and his 2-year-old sister s car seat was not properly secured, investigators said.

Postlewait observed the Subaru as it changed lanes erratically and tailgated other vehicles until they moved out of the way. As the Subaru passed vehicles, the startled drivers instinctively stepped on their brakes, nearly causing several chain-reaction crashes, said Don Thomson with the Marion County Sheriff s Office.

The deputy said Bankston, 24, challenged him to race when he pulled into position to stop the car.

As it sped off, Postlewait measured it's speed at 109 miles an hour, Thomson added.

Bankston was eventually pulled over near Keizer and arrested for reckless driving and reckless endangerment.

When asked why he was speeding, Postlewait said he told him he had recently installed a turbo-charger, which boosted the power.
