It's Brown without a doubt. The reason this info seems "new" to people is that police have procedures about releasing information in an ongoing investigation. One of the many reasons why rioting or even "peacefully protesting" before the info has come out, are incredibly stupid.
The cop who shot him had been looking for he and his friend in particular, after the store owner called them about the strong armed robbery.
I heard this info days ago, but didn't mention anything because it was "unsubstantiated at that time" so I kept my mouth shut (see how that works?) but it was going through the grapevine. So too was the fact that the officer had serious facial injuries and was in the hospital thanks to Brown.
Why do you think the very store they stole from was burned to the ground and robbed blind in the riots? Most importantly, why do you think they spraypainted "Snitches get stitches" on the side of said store? The community knew the basic outline: Brown and his friend had stolen from the store, the store owner had the audacity to report this crime to authorities, and the rest was history.
Oh and obviously this isn't about "being executed for stealing cigars" this is about him being shot after he tried the same thing on the officer as he did the store owner: namely, using his large size and lack of morals as a way to avoid consequences - he beat the officer, tried to get his weapon, and likely would've murdered him had he succeeded.
