Borderline Bar

Matt Wennerstrom, a 24-year-old man who helped people escape the Borderline Bar & Grill shooting in November 2018, was killed Saturday upon colliding with an SUV in Newbury Park.

Video from cameras worn by deputies who responded to a mass shooting at a Southern California bar in 2018 and recordings of calls for help released Tuesday captured the chaos, horror and confusion of the massacre that left a dozen people dead.
