FERGUSON, Missouri The last moments of Michael Browns 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 arms 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.
Browns killing on Saturday afternoon has sparked protests and rioting in this small, hardscrabble suburb of St. Louis, where tensions continue to rise between the police and the largely black, mostly poor community. Browns shooting lifted the lid on a pot that had long been bubbling .
The police say the officer shot Brown after the teen shoved the officer and tried to wrestle the officers gun from him. But a number of witnesses, including Johnson, refute those claims. And in the wake of the shooting, the Ferguson Police Department has asked the St. Louis County police to step in and take over the investigation.
Meanwhile, the identity of the police officer involved in the shooting has not yet been identified. It is known, however, that the officer who shot Brown has been placed on paid administrative leave.
But as darkness fell over Ferguson on Monday, ongoing protests were stifled by rubber bullets and tear gas fired at protesters by officers, according to witnesses.
Local branches of the NAACP have called on the Justice Department and federal and state law enforcement officials to take over the investigation from local police. The FBI has joined the investigation and the Justice Department has said it is keeping an eye on the case. Attorney General Eric Holder on Monday said that the FBI will help local authorities undertake a thorough, fair investigation.
For its part, Browns family has hired local attorney Anthony Gray and Benjamin Crump, a civil rights attorney who represented the family of Trayvon Martin.
That baby was executed in broad daylight, Crump said during a press conference Monday afternoon, standing beside Browns mother and father. Crump told a crowd of several dozen that Brown was shot and left in the road like an animal.
He was a good boy who didnt deserve any of this, said Michael Brown Sr., the teens father.
I just wish I could have been there to help my son, the boys mother, Leslie McSpadden said through tears.
On Monday, McSpadden and Browns father had planned to drop Brown off at a nearby technical college for the start of his freshman year. Instead, the family is making burial arrangements.
We cant even celebrate because we have to plan a funeral, McSpadden said.
Johnson, who said he moved into the neighborhood about eight months ago, said he met Brown three months ago and the two became fast friends.
Everyone elses mentality be on some nonsense, silliness, Johnson said. But Mike had his mind set on more than that, helping others. I just got a good feeling from being around him.
About 20 minutes before the shooting, Johnson said he saw Brown walking down the street and decided to catch up with him. The two walked and talked. Thats when Johnson says they saw the police car rolling up to them.
The officer demanded that the two get the fk on the sidewalk, Johnson says. His exact words were get the fk on the sidewalk.
After telling the officer that they were almost at their destination, Johnsons house, the two continued walking. But as they did, Johnson says the officer slammed his brakes and threw his truck in reverse, nearly hitting them.
Now, in line with the officers drivers side door, they could see the officers face. They heard him say something to the effect of, whatd you say? At the same time, Johnson says the officer attempted to thrust his door open but the door slammed into Brown and bounced closed. Johnson says the officer, with his left hand, grabbed Brown by the neck.
I could see the muscles in his forearm, Johnson said. Mike was trying to get away from being choked.
Theyre not wrestling so much as his arm went from his throat to now clenched on his shirt, Johnson explained of the scene between Brown and the officer. Its like tug of war. Hes trying to pull him in. Hes pulling away, thats when I heard, Im gonna shoot you.
At that moment, Johnson says he fixed his gaze on the officer to see if he was pulling a stun gun or a real gun. Thats when he saw the muzzle of the officers gun.
I seen the barrel of the gun pointed at my friend, he said. He had it pointed at him and said Ill shoot, one more time.
A second later Johnson said he heard the first shot go off.
I seen the fire come out of the barrell, he said. I could see so vividly what was going on because I was so close.
Johnson says he was within arms reach of both Brown and the officer. He looked over at Brown and saw blood pooling through his shirt on the right side of the body.
The whole time [the officer] was holding my friend until the gun went off, Johnson noted.
Brown and Johnson took off running together. There were three cars lined up along the side of the street. Johnson says he ducked behind the first car, whose two passengers were screaming. Crouching down a bit, he watched Brown run past.
Keep running, bro!, he said Brown yelled. Then Brown yelled it a second time. Those would be the last words Johnsons friend, Big Mike, would ever say to him.
Brown made it past the third car. Then, blam! the officer took his second shot, striking Brown in the back. At that point, Johnson says Brown stopped, turned with his hands up and said I dont have a gun, stop shooting!
By that point, Johnson says the officer and Brown were face-to-face. The officer then fired several more shots. Johnson described watching Brown go from standing with his hands up to crumbling to the ground and curling into a fetal position.
After seeing my friend get gunned down, my body just ran, he said. He ran to his apartment nearby. Out of breath, shocked and afraid, Johnson says he went into the bathroom and vomited. Then he checked to make sure that he hadnt also been shot.
Five minutes later, Johnson emerged from his apartment to see his friend Mike dead and in the middle of the street. Neighbors were gathering, some shouting, some taking pictures with their cell phones.
Freeman Bosley, Johnsons attorney, told msnbc that the police have yet to interview Johnson. Bosley said that he offered the police an opportunity to speak with Johnson, but they declined.
They didnt even want to talk to him, said Bosley, a former mayor of St. Louis. They dont want the facts. What they want is to justify what happened
what they are trying to do now is justify what happened instead of trying to point out the wrong. Something is wrong here and thats what it is.
Johnson says he understands why the tension has boiled over into violence. As the protests seeking justice in Browns death have grown larger and more volatile, Johnson says he has joined them.
There are two crowds. An older crowd that wants justice but theres anger. Then its the younger crowd that wants revenge but theres anger there, too, Johnson said. What do you expect when something is steadily occurring and its hurting the community and nobody is speaking out or doing anything about it. I feel their anger, I feel their disgust.
