Would you believe the gematria of the phrase ‘going postal’, a phrase that came about from postoffice shootings in decades past?
Going Postal = 54 / 54
Jesuit Order = 54

As for this shooting coming on October 12, that is where ‘USPS’ fits in.
USPS = 12

Think about how the Jesuits operate in 112 countries…
