(FOXNEWS) — A purported conversation captured on a YouTube video apparently shot in the immediate aftermath of the fatal police shooting of Michael Brown has a possible witness saying the unarmed 18-year-old charged at the officer who fired the shots that have led to more than a week of sometimes violent demonstrations in the St. Louis suburb of Ferguson.

Amid angry condemnations of the police and pledges to move away from the mean streets of Ferguson, one man describes what he saw as he witnessed the shooting. He seems to describe how the 6 foot, 4 inch, 300-pound Brown tussled with Police Officer Darren Wilson and charged him, an account that may corroborate Wilson’s story and cast doubt on claims of other purported witnesses who say Wilson shot Brown as he ran away, his hands in the air.

“I mean, the police was in the truck [sic] and he was, like, over the truck,” the man says. “So then he ran, police got out and ran after him.

“The next thing I know, he comes back towards them. The police had his guns drawn on him.”
