Two people arrested near Seattle with a car belonging to a slain woman are responsible for her murder, police in California say.

Hercules police detectives are recommending prosecutors charge Darnell Washington, 24, and his wife, Tania Washington, 25, with murder for the stabbing death of Susie Ko, who was found dead in her home in the small town northeast of San Francisco Oct. 5.

Since 2006, Ko and her husband, Kelvin Ko, lived part-time in Boise, where Kelvin Ko, 60, works as a contract examiner with the Idaho Department of Insurance. A neighbor found Susie Ko dead after Kelvin Ko called from the Oakland airport and said she hadn't picked him up from his flight from Boise and wasn't answering her phone.

The couple's 2011 Subaru with Ada County license plates was missing from their driveway. A police officer spotted the vehicle near Seattle Tuesday; the Washingtons were arrested at gunpoint after a high-speed chase.

Darnell Washington escaped from the San Bernardino County Jail Aug. 28 with the help of his wife, authorities say. He's accused of shooting at Los Angeles County Sheriff's deputy Sept. 2 and carjacking at least two vehicles with his wife. The deputy, whose injuries were not life- threatening, also fired shots, police say.

Hercules police detectives traveled to Seattle to interview the couple, who are booked in the King County Jail. Detectives plan to present their case to the Contra Costa District Attorney's Office late next week. The suspects face murder and car theft charges.
