The two arrested, a 25-year-old woman and her 24-year-old husband, are suspects in a crime spree beginning in Southern California in August when the man had escaped from the San Bernardino County Jail.
SeaTac Airport police apprehended the suspects after a pursuit ending near the airport, about 30 minutes south of Seattle.
Hercules police say the two were arrested for driving the car, but there's no confirmation they are responsible for Ko's.
The man is also the suspect in the attempted murder of a police officer after a shootout with a Los Angeles County Sheriff's deputy on Sept. 2.
