This is the shooter:
The other guy you spoke of was briefly posted saying it was him, he gave himself up to the police. He was not a shooter, was brother of one of the black lives matter speakers from what I was told.
Most of those posting that pic (I was one) removed them from Twitter when it was quickly determined he was not involved.
Thank you. I was keeping up with this on FR and the scanner app on my phone and fell asleep at around the 650th post.
