The last moments of Michael Brown’s life were filled with shock, fear and terror, says a witness who stood just feet away as a police officer shot and killed the unarmed teen. “I saw the barrel of the gun pointed at my friend,” said Dorian Johnson, 22. “Then I saw the fire come out of the barrel.” Johnson, in an exclusive interview with msnbc, said what began as an order by a police officer to ‘get the f— onto the sidewalk’ quickly escalated into a physical altercation and then, gunfire.

“I could see so vividly what was going on because I was so close,” said Johnson, who said he was within arm’s reach of both Brown and the officer when the first of several shots was fired at the teen. Johnson says he feared for his life as he watched the officer squeezing off shot after shot.
