There's no logic behind the "planting the body."
Never a cohesive, rational explanation for exactly how TH's remains ended up in SA's burn pit in a planting scenario.
- The planter or planters would have arranged to get TH's phone, camera, PDA and leave that in the burn barrel near SA's trailer, without being seen and without Bear the dog alerting to a stranger.
- The planter(s) coincidentally arranged for SA to be seen dumping a bag in the barrel the afternoon of TH's disappearance, then arranging for a fire to be lit in the burn barrel.
- Someone would have to get a hold of TH and kill her, wearing the clothes she wore while at ASY.
- That person or persons would have to burn her body and get some of her remains intertwined within steel belts from burned tires.
- Then her charred bones, tooth (or teeth) and other burned items (jean rivet(s) etc) would have to be transported to ASY, along with the melded steel belts that intertwined with some of TH's bones.
- Then those charred bones would have to be spread in the burn pit outside of SA's trailer.
- The planter felt it was important to put one or more of TH's larger bones in the burn barrel between SA & Janda trailers and did so without any detection or alerting by Bear.
- This master planter would need to be at ASY long enough to do all this planting, without detection, having gotten past Bear the German Shepard, and also cause Bear to not bark at the stranger approaching with TH's remains.
- The cremains were not just sitting on top in the burn pit, they were discovered underneath a layer of ash and dirt, so the planter needs to make that happen. It was coincidentally very helpful for SA to leave tools at the burn pit that would help the planter plant those charred bones and steel belts melded with some TH bones in the pit -- shovel, hacksaw blade, hammer.
- Then the planter or planters need to make sure SA used his fire pit to coincide with TH's day of disappearance, knowing she had not been seen or heard from by anyone else from the time she was seen walking toward SA's trailer door.
- The planter was able to make sure TH never used her phone again at the same time she happened to be at ASY and in the presence of SA.
- Then the planter or planters had to make sure investigators found TH remains that were buried under the layer of ash in SA's burn pit. They didn't make it easy for her remains to be found -- it required a trained cadaver scent dog to alert on the burn barrel which ultimately led investigators to SA's trailer, burn pit and cremains discovery.
- Then, in a master stroke of pure evil genius, the planter ensured that SA's nephew, the one who definitely helped SA clean a 3x3 area of SA's garage floor with 3 chemicals, staining his pants with bleach whilst doing so, and then helping his uncle start a large fire that burned for hours, felt traumatized to the extent that he talked to his female cousin and had her so troubled she seeked out counseling at the guidance counseling office at school, where she talked about blood, concrete, body being moved and her concern about her cousin.
Not even Agents Scully or Mulder would believe that one.
Teresa Halbach's alleged bones were found in various locations not just one location, how do you explain that?
