We had the same thing happen in my town here in Texas. Some kids found a shotgun. Their first target was the backdoor of a store and that reminds me of the first shot at the Michael's store. The next shooting was at people as they drove around. Their last shot was at a kid who was driving a car with his mother. The victim was blinded in one eye.
I'm starting to think the FBI profiler was right but I want more information.
All we know at the moment is a .224 bullet was found. I'm not even sure they have the vehicle correct or if they found any cartridge cases.

Speaking of the first attack at Michael's store I was wondering if the reason the sniper missed the intended target was because of the light refraction the glass pane? I'm not an expert in these matters but IF there is a refraction quality to glass causing the sniper to miss, it could indicate that while the perp is a good shot he may not be as experienced as some people suggest. IOWs, this sicko is not a trained sniper with military training.
In any event, the sniper never again tried shooting people through glass windows, which suggests that the perp suspected that the glass pane, for whatever reason, was why he missed. Which again points to a degree of inexperience notwithstanding all the subsequent open field accurate shots.
