His name is Ali Muhammad Brown. He was the same guy who killed the kid in N.J. who was white. The others were black. He according to various news reports used Grinder to find his victims. Straights don’t use Grinder
I see; the kid in NJ was killed randomly by a raiding party. His parents were furious that it was implied he knew the savages (by saying he had been targeted rather than just hated for his whiteness).
