Dorian Johnson's account
According to Michael Brown's friend, Dorian Johnson, who was walking with Brown at the time, the police officer pulled up beside them and said, "Get the fuck on the sidewalk." Johnson said the young men replied that they were "not but a minute away from [their] destination, and [they] would shortly be out of the street". Johnson states that the officer drove forward without saying anything further, only to abruptly back up, positioning his vehicle crossways in their path, almost hitting the two men. Said Johnson, "We were so close, almost inches away, that when he tried to open his door aggressively, the door ricocheted both off me and Big Mike's body and closed back on the officer."
At that point, the officer, still in his car, grabbed Brown through the open window around the neck. Brown tried to pull away, but the officer continued to pull Brown toward him.
According to Johnson, Brown "did not reach for the officer's weapon at all", insisting that Brown was attempting to get free of the officer rather than attempting to attack him or take his weapon from him.
At that point, according to Johnson, the officer drew his weapon, and "he said, 'I'll shoot you' or 'I'm going to shoot,'" and almost instantaneously fired his weapon, hitting Brown.
Following the initial gunshot, Johnson said that Brown was able to free himself, at which point the two fled for their lives. The officer exited the vehicle, after which he fired a second shot, striking Brown in the back according to Johnson. At that point, according to Johnson, Brown turned around with his hands in the air and said, "I don't have a gun. Stop shooting!" The officer then shot Brown several more times, killing him. Johnson's attorney stated that officer Wilson did not attempt to resuscitate Brown, did not call for medical help, and “he didn’t call it in that someone had been shot.”
The resulting autopsy from Dr. Michael M. Baden revealed that all bullets were fired into the front of Brown, which appears to contradict Johnson's account that Brown was shot in the back.
Piaget Crenshaw's account
Piaget Crenshaw, a witness to the shooting, said that from her vantage point, it appeared that the police officer and Brown were arm wrestling before the officer initially shot Brown from within his vehicle. The officer then chased Brown for about 20 feet before shooting him again. Crenshaw stated, "I saw the police chase him...down the street and shoot him down." She added that when Brown then raised his arms, the officer shot him two more times, killing him.
According to earlier reports that appeared on August 10, 2014, Crenshaw said she saw Brown attempt to flee with his hands in the air and that he was hit with several shots as he ran.
On August 18, 2014, after the release of Baden's autopsy report, Crenshaw told CNN's Michaela Pereira that no shots hit Brown's back as he was running away, "Clearly none of [the shots] hit him, but one, I think, did graze him as they said on the autopsy report. At the end, he just turned around ...after I'm guessing he felt the bullet grazed his arm, he turned around and he was shot multiple times."
Police account
In a news conference on August 10, St. Louis County Police Chief Jon Belmar stated, "The genesis of this shooting incident was a physical confrontation" during which Brown "physically assaulted the police officer". According to Belmar, the officer attempted to exit his vehicle but was pushed back into the car by Brown, who then assaulted the officer inside the car. Brown then allegedly attempted to seize the officer's gun, which was fired at least once during the struggle. Belmar acknowledged that "more than a couple" of shots were fired in the course of the encounter.
Ferguson Police Chief Thomas Jackson later stated that the officer who shot Brown was injured in the incident. The Ferguson City Police Department had declined to identify the officer involved in the shooting, who had been placed on administrative leave, but released Officer Wilson's name on August 15, 2014. Dashboard cameras are not used in Ferguson police cars.
Tiffany Mitchell's account
Tiffany Mitchell, in an interview with St. Louis television news station KMOV, said she arrived in the area near the beginning of the altercation. She said that she was watching as the first gunshot was fired while the police officer, but not Brown, was still in the vehicle, at which point she attempted to retrieve her cell phone in order to film the unfolding event, but stopped and sought cover when she heard gunshots.
As Mitchell described events, "As I pull onto the side, the kid, he finally gets away, he starts running. As he runs the police get out of his vehicle and he follows behind him, shooting. And the kid's body jerked as if he was hit from behind, and he turns around and puts his hands up like this, and the cop continued to fire until he just dropped down to the ground and his face just smacks the concrete."
Bystander heard on video of incident
Some sources suggest that an unidentified bystander, heard speaking in the background of a video filmed shortly after the shooting, appears to confirm the police account. According to the Daily Caller, after Brown stopped running and turned his back, "Next thing I know he’s coming back towards the police. The police had his gun drawn on him," according to the witness. "Police kept dumping on him, I’m thinking that the police missed him,” he continued, saying that he heard “at least five shots”. The bystander continued, "I think ... dude start running, kept coming toward the police," which the Daily Caller says contradicts other witnesses' accounts.
