HERCULES -- Police announced Wednesday that Darnell and Tanya Washington had been charged with murder in the Oct. 5 stabbing death of 55-year-old retired schoolteacher Susie Ko.
The husband and wife face at least seven other charges in Contra Costa County, along with a special circumstances enhancement that makes them ineligible for bail, according to Hercules police spokeswoman Connie Van Putten.
The pair was arrested Oct. 10 in the city of SeaTac, in Washington state, after a police officer attempted to pull them over in a Subaru Outback reported stolen from Ko's home in the 100 block of Ash Court. They rammed the officer's car, led police on a brief pursuit and surrendered only after they were completely boxed in, authorities said.
They are also suspects in a monthlong crime spree that included Tanya Washington helping Darnell break out of a San Bernardino County jail, and the nonfatal shooting of a Los Angeles County sheriff's deputy.
The pair are both charged with murder, first-degree robbery, carjacking, first-degree burglary, second-degree robbery, auto theft, possession of a stolen auto and possession of stolen property. Darnell Washington is also charged with being a felon in possession of a firearm.
A warrant for extradition was filed in Contra Costa Superior Court on Wednesday and will be forwarded to King County Washington, Van Putten said. The pair will be extradited to California at a later date.
