Re: the three mysterious mounds. I lived in a rent house that was under repair by two guys who were friends with each other and then got in a huge, vocal argument with each other. I had to leave before it ended, but the next day, there was a plot of upturned earth and no sign of either man. Their absence went on for days. My roomie and I speculated that the loser of the argument might be buried there but neither of us wanted to check! Later, both men were back on the job, and it turned out that one of the guys had overheard me saying something about wanting a garden and thought to give some help by starting the plot.
So, in the farmer's case, it might be that there was someone wanting to plant--an illegal cash crop perhaps? I admit it doesn't make much sense that there were three plots. Also, it doesn't make much sense because Louisiana landowners are in my experience especially passionate about their landownership. For this reason, a closer watch might be kept on one's property here. I guess I'm talking myself out of the case I was making here...
Moving along to look at this from another angle...the number of plots has me wondering. Could it be that there was something planned on a grander scheme by BSL? (i.e., three abductees?)
The method by which he abducted MS, the bump-and-grab, seemed to indicate more of a mind geared more toward spontaneity than planning. Then I think back about the multiple IDs of other women found in his home.
An earlier poster wondered how he might be in a position to collect them. If he has the IDs of MS and LP, these are women whose lives he invaded in the worst way. There are other, less permanent ways of collecting IDs however. We know BSL has burgled before. What if he burgled or creeped (a la Charles Manson) homes of potential victims? This would provide him with an opportunity to lift other IDs.
This really bugs me because in addition to their legitimate, legal purpose, the IDs also serve as a "calling card" and perhaps eventually as a different kind of trophy. What better way to remember what a target looks like and where she lives? Another opportunity may have been at bars or grocery stores or other places where women might leave handbags unattended for a moment. If only the ID were gone, women might attribute it to misplacing the item rather than anything suspicious.
All this makes me wonder if BSL plans more than some of us gave him credit for...
And all this is also just MSO (my speculation only)
