THAT PICTURE OF THE GUY CARRYING THE RIFLE IS NOT THE PERP!
His brother told local media his brother turned the gun right in to police when shooting started.
I thought as much. I stated he seems to not be connected because he is street level and the shooters are from a parking garage or high area. He was probably carrying a rifle to make a political point and not involved - with that said - he needs to be found - he is now a person of interest.
