For some reason all the assaults in SF & Oakland never show the skin color of the perp....
I have not been following closely, but last I saw he shot up the parlors he visited for a rub & tug with the stated reason that shooting them up would get police investigation & result in them being shut down because he was too much of a coomer to stop going there as long as they were open.
Speculation that sounds likely to me is he tried to be captain save-a-ho and pretty woman some sideways vagina, realized he had been getting grifted, and enacted the simps revenge.
