SF District Attorney Boudin Announces the Expansion of an MOU for Nine Bay Area Counties to Respond in the Event of a Mass Casualty

San Francisco, CA - Today, on the third anniversary of the Route 91 Harvest Festival mass shooting in Las Vegas, San Francisco District Attorney Chesa Boudin announced the signing and expansion of a Memorandum of Understanding (MOU) between nine Bay Area counties to streamline a coordinated response in the event of a mass casualty crime incident. The nine counties include San Francisco, Alameda, Sonoma, Contra Costa, Marin, San Mateo, San Joaquin, Solano, and Santa Cruz counties. The MOU allows any participating county impacted by a mass casualty crime incident to request shared resources and personnel from the surrounding counties. This is critical because a mass casualty event can quickly deplete county resources and victim or witness support staff, given the high number of people affected by suffering injuries, witnessing the incident, or experiencing the loss of a loved one. In such an event, the other counties would deploy staff and support to the affected county to ensure that there are sufficient victim and witness support providers available in the aftermath of a mass violence event.
