Oakland Woman Charged As Accessory In Walnut Creek Double Murder Case

An Oakland woman who was allegedly in a romantic relationship with a man accused of killing his wife and mother-in-law in Walnut Creek earlier this month has been arrested and charged with being an accessory after the fact following the deaths, prosecutors announced Tuesday. Linlin Guo and her mother Beimin Cheng were found dead inside a home after Walnut Creek police responded on Sept. 18 to a report of a disturbance with possible gunfire in the 100 block of Kelobra Court, located just north of Ygnacio Valley Road and east of Oak Grove Road.

Guo’s husband Howard Wang, 43, was arrested and charged with the murder of the two women, and the Contra Costa County District Attorney’s Office on Tuesday announced Yan Wang, 45, who has no familial relation to Howard Yang but was in a romantic relationship with him, faces two felony and one misdemeanor charge in the case. Yan Wang has been charged with being an accessory after the fact and first-degree residential burglary, both felonies, and misdemeanor destroying evidence. Prosecutors said she allegedly aided Howard Wang with knowledge after the killings and with the intent to help him avoid punishment. On Sept. 19, she allegedly entered the home where the killings happened with the intent to commit larceny, and on Sept. 18 also allegedly destroyed cellphones to prevent evidence from coming to light, prosecutors said. Yan Wang was set for arraignment on the charges Tuesday afternoon in Contra Costa County Superior Court in Martinez. “This case serves as a sobering reminder of domestic violence’s far-reaching consequences,” Contra Costa County District Attorney Diana Becton said in a statement. “Our office will pursue justice with the seriousness and urgency this tragedy demands.”
