Overview

• Contra Costa County prosecutors charged Yan Wang, 45, of Oakland, with felony accessory after the fact and first-degree burglary, plus misdemeanor destroying evidence tied to the Sept. 18 killings of Linlin Guo and Beimin Cheng.
• Authorities allege she destroyed cellphones on the day of the slayings and entered the home the next day to remove items, later discarding phones in trash cans near her residence in Oakland.
• After a brief court appearance Tuesday, a judge ordered her held without bail and reset her arraignment to Oct. 3 to align with the co-defendant’s hearing.
• Howard Wang, 43, is charged with two counts of murder for allegedly slashing the victims’ throats and firing gunshots while falsely claiming he shot at a fleeing intruder; he is due in court Oct. 3.
• He also faces counts of criminal threats and witness tampering tied to alleged prior abuse, and the couple’s 8-year-old twins are now in protective custody, while a murder conviction could mean life without parole.
