Walnut Creek was shattered last week by a double homicide that left two adult women dead and has since led to the arrest of Howard Wang, known to both victims, and Yan Wang, identified as the girlfriend of Howard Wang. According to a social media post from the Walnut Creek Police Department, officers responded to a 911 call reporting possible gunfire on September 18 at approximately 11:45 PM. Upon arrival, they discovered the grisly scene.

Police acted swiftly and arrested Howard Wang, who is being held at the Martinez Detention Facility without bail. The case took another turn last Wednesday when Yan Wang was taken into custody near her Oakland residence. She's accused of being an accessory after the fact, first-degree residential burglary, and destroying evidence; thus, charges were filed by the Contra Costa County District Attorney's Office, according to the department's update. The investigation, at present, suggests that there are no remaining suspects, and the authorities assert that there is no longer a threat to public safety.

The collaborative investigative efforts among the Walnut Creek Police Department, Concord Police Department, and the Contra Costa County Office of the Sheriff hint at a determination to bring clarity to the circumstances of the tragedy; accolades were specifically mentioned for their assistance in this complex case. The Walnut Creek Police Department has been cautious with the flow of information but remains open to public input, encouraging anyone with information to reach out at (925) 943-5844 or to use the anonymous tip line at (925) 943-5865.
