A Bay Area husband accused of brutally killing his wife and mother-in-law at their home while his young twin daughters were nearby is now facing a third murder charge for a deadly shooting in the Los Angeles area — as his mistress has links to all three slayings. Howard Wang, 43, was charged in the September 2025 killings of his wife, Linlin Guo, 37, and her mother, Beimin Cheng, who were found were their throats slashed inside the couple’s Walnut Creek home. Wang’s alleged lover, Yan Wang, 45, was charged as an accomplice over accusations she helped destroy evidence and misled investigators after the killings.
