Wonder where you heard that? I certainly haven't heard any such thing. At least not from the known witnesses
all of the witnesses that I've seen reported, including the guy who was tweeting about it live, stated that Brown had stopped, turned with hands raised and the officer continued to fire.
The witnesses all said, I believe, that while running away he flinched as if shot and stopped, raised his hands and turned to face the police officer. The flinch could easily be explained by a near miss.
"Neither woman, who gave their statements to St. Louis County police, say they saw Brown enter the vehicle.
Instead, a shot went off, then the teen broke free, and the officer got out of the vehicle in pursuit, the women said.
“I saw the police chase him … down the street and shoot him down,” Crenshaw said. Brown ran about 20 feet.
“
Michael jerks his body, as if he’s been hit,” Mitchell said.
Then he faced the officer and put his hands in the air, but the officer kept firing, both women said. He sank to the pavement."

"
At that point, Johnson says Brown stopped, turned with his hands up and said “I don’t have a gun, stop shooting!”
By that point, Johnson says
the officer and Brown were face-to-face. The officer then fired several more shots. Johnson described watching Brown go from standing with his hands up to crumbling to the ground and curling into a fetal position."
