San Francisco police confirmed Wednesday night a man was killed in an officer-involved shooting in the Bayview area. San Francisco Police Chief Gregory Suhr said a man, who matched a description of a suspect who stabbed someone in the area around the same time, was holding a knife when he was shot and killed by police, the San Francisco Examiner reports. Suhr added that officers fired beanbags and took other shots at the ground before the fatal shooting. An Instagram video surfaced online purporting to show the moments before the man was shot and killed. Police can be seen surrounding the man, who is shuffling to the ground before the camera cuts away and a barrage of bullets are heard over audio. Suhr said authorities have witness video but could not confirm the Instagram post.
