A woman who would only give her first name described Wilson's version of events to a local radio station this week, claiming Brown not only attacked Wilson first but rushed him headlong after the initial shot was fired.
A law enforcement source has told CNN the woman's account matches the description Wilson has given to investigators.
In the interview, Josie said Brown and Johnson were walking in the middle of the street when Wilson asked them to move to the sidewalk.
After a brief argument, Wilson received a call about the convenience store robbery and noticed Brown matched the description of the suspect and was carrying a box of cigars in his hand, Josie said.
Wilson pulled alongside the two men again, according to Josie, who said Brown then pounced on the officer.
“Michael just bum-rushes him, just shoves him back into his car, punches him in the face," she said.
The two men struggled for Wilson's service weapon, which went off once inside the car, she said.
Brown and Johnson fled, she said, and after another verbal exchange at a distance of about 35 feet, Brown charged at Wilson.
"All of a sudden he just started to bum-rush him; he started to run at him full speed,” she said in the interview. “He just kept coming; it was unbelievable.”
Wilson then opened fire a second time, she said, killing Brown.
