The pics of him are a white dude. Blonde hair, probably wig. T=shirt with logo and hat. Blurry, cant make out t shirt design. That would give a clue.

Yea, white dude. There was a tweet from somebody saying the bomber was his brother and he was targeting NRA, which indicates left wing scumbaggery.

I got my money on ANTIFA, Hogg inspired type. Also stupid enough to mail his own bombs at Fed EX. Another clue he's a lefty.

I thought the shirt was maybe a dolphin.
