Well then that would include the three ladies killed just up the road at the Yountville veterans Home.(2018) One of them was pregnant.https://en.wikipedia.org/wiki/Yountville_shooting

A stand-off started at around 10:30 am when a gunman, later identified as Albert Wong, a 36-year-old U.S. Army veteran of the War in Afghanistan, entered the facility during a going away party.[7] The first 911 call of the incident was received around 10:20 am, and by 10:22 am the dispatcher had named Wong as the perpetrator and that he was armed with a semi-automatic weapon and large quantities of ammunition. Wong initially released veterans and other staff members, holding only Jennifer Gonzales Shushereba, a psychologist, Jennifer Golick and Christine Lobber, the clinical and executive directors of Pathway Home respectively.
Napa County deputies were some of the first to respond to the scene.At about 10 minutes after the initial 911 call[8] Wong exchanged gunfire with Napa County Sheriff's Department Senior Deputy Steve Lombardi and then retreated into The Pathway Home building. After the shootout there was no further contact with Wong or any of the hostages, although three hostage-negotiation teams were on site. At around 6:00 pm, after negotiators from several agencies failed to contact him, California Highway Patrol officers entered the room and found everyone in it shot to death. His cell phone was later discovered in his parked car.
Wong was found dead of a self-inflicted shotgun wound in the second-floor room where he had killed the three female staffers.[11] The Napa County Sheriff's Coroner determined that Shushereba was 26 weeks pregnant at the time of the incident and that her "unborn baby died due to lack of oxygenated blood caused by her mother's death."State Senator Bill Dodd reported that it was reasonable to believe that the three hostages were killed during or shortly after the initial exchange of gunfire with officers.
