Just some thoughts rumbling around in my head...
- Say, Brian did, in fact, arrive at his parents' home on Sept. 1-2.
-"Mom! You gotta help me! I'm in so much trouble! Something happened to Gabby!"
- "Oh! my baby! Of course! We'll do whatever you need." So they find a PASSPORT COUNTERFEITER. ..Use their retirement money, get him new IDs, new passport, fake name, bleach his eyebrows , mustache, and beard, dressy casual clothes, fly him somewhere with cash, on Sept. 4-5.
-Then all those false leads about where he's gone.
-So, by now, he's already settled in Mazatlan.
