I am not convinced she didn't remain on St. Landry. There is some funny going on, a I remember early on LE talking about the blur caught from inside a building. IMO this may have been at 224, a two-building, two-story office complex with large, smoked, plate-glass windows on the second floor facing the street. These rooms in front at the top look like the CEO offices to me, and it's possible there was a camera in one of them pointing outward, or another cam hidden that I didn't see.
But then again, the blurry image could have come from the LCG drive-thru cam.
I don't know... The key is why she wasn't on the 216 footage, or maybe if somehow she WAS, and this was discovered AFTER the early press conference, and LE just decided to keep ot to their vest. I don't think we've been given all the cam info that LE has, and I'm not willing to rule out that she made it farther down St. Landry than people think.
There's something going on here that I can't put my finger on... and it's the key, of course to what her actual route was.
