Shocking visuals: Live stream captures moments of Florida shooting

A videogame participant has shot dead two people before killing himself in a video game tournament in Jacksonville, Florida. The online video game tournament was being livestreamed from a Florida mall. The gunman opened fire, killing multiple people and sending many others to hospitals. The online video that appeared to capture the scene right before the shooting began are being investigated. Moments before the first of a dozen gunshots ring out, a red dot that appears to be a laser pointer is visible on the chest of a player.
