One of the last people who saw Michael Brown alive says the unarmed teen was shocked and scared that a cop attempted to choke him and, ultimately, gunned him down. Dorian Johnson, 22, was Brown’s friend and an eyewitness to the murder. He rejected police claims that Brown shoved an officer, and instead described how a cop told them to “get the f—k on the sidewalk,” and then threw his vehicle in reverse, nearly hitting them. Johnson said the officer threw the door open. When it bounced back after hitting Brown, the cop grabbed Brown by the neck, nearly choking him. “He’s trying to pull him in. He’s pulling away, that’s when I heard, ‘I’m gonna shoot you,’” said Johnson. “I could see so vividly what was going on because I was so close. I saw the barrel of the gun pointed at my friend. Then I saw the fire come out of the barrel.” The identity of the officer who shot Brown has not been revealed. He is on paid administrative leave.
