Because they still had so many explosives, I believe there would be two more sent out to ???? Same routine. So I would look for an event....or the perimeter of a stadium or possibly a building entrance/lobby....like the bomber in Jordan several years back.
According to the 137 day theory, a event should happen on 4/22 [Hitt event- extraordinary coincidental lining up of an emotion-releasing event (i.e., false flag event)].
That's three days from now - Monday.
Anything big happening on Monday? Mark your calender.
