On Thursday morning, Bellevue PD's Mike Johnson said investigators are testing the car Biryukova was driving Sunday when she said it ran out of gas, prompting her to leave Sky alone in the car.
The car, a silver 1998 Acura Integra, is at the police department's secure vehicle lab, Johnson said. It will be taken for a test drive so investigators can determine if any mechanical problems would have caused it to stop running on Sunday. On Wednesday, Johnson said police found a "sufficient amount of gas" in the car, enough to run it "for a considerable distance."
The tests had not been completed as of mid-afternoon Thursday, but Johnson said he believes they will be done by the end of the day.
