Multiple witnesses say they saw Brown reaching into the vehicle and even struggling with Wilson. Physical evidence revealed that two shots where fired inside the vehicle. There was also Browns blood inside the drivers area of the cab, suggesting that brown was shot in the hand inside the truck.
On the contrary, several witnesses stated they never saw brown in the vehicle. Their stories changed after the physical evidence was provided. These same people were likely the ones who changed their story from "he had his hands up" to "i never actually saw anything"
This all came from the prosecutor last night during his announcement.
