It was a black woman that did the shooting
It didn’t look like that in the pix I saw, taken from very close to the shooter. But it’s hard to say...I originally thought the woman shot was Hispanic, because she looked to have darker hair and skin and be much younger in the first photo I saw. She wasn’t, obviously, but other people must have thought this too, since the rumor was that a 16yr old girl had been shot.
Most of these photos have now been disappeared from the internet, but I hope somebody has been saving them.
