If LE thinks the girls are being held somewhere, why are they draining the lake? And taking forever to do it...
Maybe to look for evidence. Maybe to divert attention and look busy to buy time. Maybe a higher up is not 100 percent convinced. Maybe they aren't 100 percent convinced. I honestly could sway towards an abduction targeted towards LM based on SM as well. I would like to think LEis doing a better job than the bumbling it appears. They appear disorganized but the family and those "in the know" (the familys inner circle)strongly believe that they are doing a great job. I guess it could be a total random event as well but that seems to be the 3rd most likely scenario IMO. At first I thought they drowned but now I am leaning towards the first two theories.
