Walnut Creek Man Charged with Double Murder, Faces Life Sentence

Howard Wang, a 43-year-old resident of Walnut Creek, has been charged with the murders of his wife, Linlin Guo, and mother-in-law, Beimin Cheng, following their deaths at their home on September 18, 2025. Wang allegedly stabbed both women and then falsely reported to 911 that he had caught the killer and fired his gun at the suspect, a story that quickly fell apart during investigation. He faces special circumstances enhancements for multiple murders, which could lead to life imprisonment without parole if convicted. Additional charges include making criminal threats against his wife in 2024 and preventing her from reporting a crime in 2023, highlighting a history of domestic violence. The case has drawn collaboration from Walnut Creek Police, Concord Police, and the Contra Costa County Sheriff's Office, with authorities urging the public to provide any relevant information. District Attorney Diana Becton emphasized the devastating impact of domestic violence and the office's commitment to pursuing justice in this case.
