I was certain in the news clips I watched that they were showing a “fed-ex” type package, but maybe they were and it wasn’t the package HE sent, (typical TV journalism using “file footage”).
I was also told by someone else here that they know he handed the package to a mail person who stamped it for time. So I guess he did run off to the post office on his way to do the deed.
The U.S. Postal Service Express Mail forms look similar to FED EX forms. I think that’s why some people are confused into thinking it was sent FED EX.
What is a FedEx-type package? Did it have a FedEx logo? These days, FedEx, UPS and the USPS use pretty nearly identical self-sealing envelopes and boxes. And it's also pretty easy to drop by a FedEx outlet, pick up a box or envelope, take it home, put your package in it, and then drop it off at the post office. They won't refuse to ship because someone else's logo is on the box.
