@Seattle1 I don't think the supposed midnight appointment at Wiechman's linked in the Freightwaves article is correct.
There has been no other mention of an appointment time anywhere else and Freightwaves only lists this as what authorities have said, but does not include which authority or a quote from anyone. Most likely just poor reporting.
The manger of Wiechman's said this particular station is not used much and truckers will unload and place their paperwork in a box. Meaning there is no one there after hours, it's a self unload process and for this there would be no appointment times. Get there when you get there sort of thing. If there was someone there at midnight and David had an appointment, then someone would have noticed David did not arrive at his appointment time and notified the search for the missing baby pork chops to begin then, instead of the next morning when a worker noticed there were not as many piggy's in the pens as there should have been.
