My guess it's MS13. Mask's are to hide all the facial tattoo's if they are in fact wearing any. Did anyone find a body with a mask on it where the shooter was taken down along with some of it's victims in a shootout?
If not I would say this a BLM or ANTIFA Soros plant
So where is the guy who wasn't on the plane then and who has buddy's that he worked along side with, noticing he didn't show up for work Monday, now?
Just curious … any special reason a whole family would get behind this operation basically throwing a black mark on their name and where the siblings will have to carry the water for this imaginary what if, in personal hit's and nefarious accusations in that they may have somehow contributed to their son or brothers demise because they didn't get him proper help.
