Nooz is reporting AR15 and handgun of some sort.
This whole thing is odd. How many black mass shooting perpetrators have there been in the last couple decades? Probably count that on one hand. Doesn't fit the bill.
Black = 13% of the population... so they can be a minority in mass shootings, too. They "should" commit about 1/8th of them. Wasn't Ft. Hood guy black also? Then there's the beltway guys.
As long as you can count all mass shootings in the last couple decades on your fingers and toes, fitting the black ones on one hand fits the strict demographic ratios. Now, including gangland mass shootings will skew that crime stat more towards blacks having more mass shootings, but it depends on if your targets in the mass shootings are middle class working folks, kids in schools, or people living in chicago ghettos.
