“”Can the packages be traced to original shipping location?””
Just a wild guess but since the stamps weren’t cancelled, I would say the packages weren’t shipped!
Just a thought - someone working at a post office could have stuck them in for mail deliveries and they were dropped off by a regular mailman? Catching something WITHOUT going through the postmark machine would have to have been done BEFORE mail/packages are put out for delivery, right? What would work better than to sneak them in to the trucks? It would have to be someone familiar with the routes to get the addresses in the right truck.
But I guess from the news reports, they weren’t found at the delivery addresses - they were found in the processing centers so forget my hypothesis. Back to the drawing board.
At Post Office:
“Hey I think this is a bomb”
“We don’t send it through the postmark machine. It’s brand new. Send it via a courier”
