Authorities in the San Francisco Bay Area are calling a shooting that left five dead during a Halloween party at an Airbnb rental a “bloodbath,” where several partygoers were armed and some showed up looking for trouble. Contra Costa Sheriff David Livingston said Friday that he knows residents in the plush San Francisco suburb of Orinda are on edge after the massive party on Oct. 31 and wanted to provide an update, although he could not yet say what sparked the shooting and who shot whom. Livingston said there is a wealth of evidence to process, including casings that littered the floors and countertops of the four-bedroom home with vaulted ceilings that hosted roughly 100 people that night.
