An Oakland woman who was in a relationship with the primary suspect in a Sept. 18 Walnut Creek double-slaying has been charged as an accessory after the fact, according to the Contra Costa County District Attorney’s Office.

Yan Wang, 45, faces two felony charges and one misdemeanor charge in the slayings of Linlin Guo and Beimin Cheng, the DA’s Office says. She was in a relationship with primary suspect Howard Wang and is accused of aiding him with knowledge after the slayings occurred.

Yan Wang, who was scheduled to appear in court Tuesday, has no familial connection with Howard Wang, the DA said. She was expected to be charged with two felony counts and one misdemeanor count related to the slayings. She allegedly destroyed cellphones to conceal evidence, the DA said.
