Another perspective on events.
Ferguson, Missouri (CNN) -- The Ferguson, Missouri, police officer who killed Michael Brown says the teenager rushed at him full speed in the moments before the shooting, according to an account phoned into a St. Louis radio station and confirmed as accurate by a source with detailed knowledge of the investigation.
According to the account on KTFK, phoned in by a woman who identified herself as "Josie," the altercation began after Officer Darren Wilson rolled down his window to tell Brown and a friend to stop walking in the street.
When Wilson tried to get out of his cruiser, Brown first tried to push the officer back into the car, then punched him in the face and grabbed for his gun before breaking free after the gun went off once.

Wilson pursued Brown and his friend, ordering them to freeze, according to account. When they turned around, Brown began taunting Wilson, saying he would not arrest them, then ran at the officer at full speed, according to the caller.
Wilson then began shooting. The final shot was to Brown's forehead, and the teenager fell two or three feet in front of Wilson, the caller said.
The account matches Wilson's telling of events to investigators, according to the source.
If true, the account represents the first telling of events from the perspective of Wilson, whose shooting of Brown has touched off nightly protests and violence in the suburban St. Louis city.
