VIDEO: Woman Calls St. Louis Radio Show with Officer's Side of Ferguson Shooting

A woman called in to a St. Louis radio show Friday to give the officer's side of the Aug. 9 events that led up to the shooting of Michael Brown.

According to the version on KFTK , phoned in by the woman who identified herself as "Josie" and said she was a friend of Ferguson Police Officer Darren Wilson's significant other,  the altercation began after 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, the caller said.

Wilson pursued Brown and his friend, ordering them to freeze, according to the account. When they turned around, Brown began taunting Wilson, saying he would not arrest them, then ran at the officer at full speed, the caller said.

Wilson then began shooting. The final shot was to Brown's forehead, and the teenager fell two or three feet in front of Wilson, said the caller, who identified herself as the officer's friend.

A source with detailed knowledge of the investigation later told CNN the caller's account is "accurate," in that it matches what Wilson has told investigators. Other witnesses have told other versions of the event.
