it appears the bag of shot penetrated her head with the "tail" described in the video the only thing visible on the outside. She's still in the hospital, as of yesterday she's still in the ICU. Terrible to see. All she was doing was standing and taking video when she was shot. Some news outlets called it a beanbag, others a rubber bullet.
News link with the printed story, but be aware if you run the embedded video, it is graphic.
