He substitute taught on the 19th in one school. (With a small dealership ya just leave a sign on the door to call a number or come back at a certain time.....They do it around here all the time.)
Family says he was with them.....Georgia would be more convenient to the airport. Picture of kids are with cousins so I'm guessing he wasn't in Alabama.
The other details don't think we know.
Harmon on Greta tonight.
So, it's pretty wide open? Not that this would prove anything, but if there is regular commercial activity in his home town (meaning; he's using credit cards, banks, ATMs, etc.) then he suddenly drops off the record for 10 days, that would be telling by itself.
I'm sure (okay, not) that the Boulder DA has gotten his bank records to look for large cash withdrawals just before the murder...
