I never knew there was a Bastrop, LA. Your post upset me at first thinking Bastrop, TX and that's a whole 'nother list of young females missing & murdered. Thank you for the geography lesson.
We did focus on this area because of the truck being found in San Jacinto Co TX, the stolen truck report being made in Montgomery Co. TX, and rumors that he has family in the area. So it is not a coincidence. If there were reason to suspect he committed crimes in Dallas, Ft Worth, Galveston, Houston area, there would be dozens if not hundreds more to consider. But it seems everything we know indicates BSL stayed fairly close (close meaning up to 300 miles) to St Landry Parish.
