Reminds me of those Adventures with Purpose guys that fueled the conspiracy bonfires with their speculation in the Kiely Rodni case.
Also, do people really think about how difficult it is and what kind of person would find it easy to move a decomposing body? I don't want to get too graphic but there's a lot of body fluids, disarticulation, etc. And why exactly would anyone do that? You're just creating the possibility of more contamination and evidence tying the body to you, rather than in a field, where the elements have eroded a lot of evidence.
The only case where I know that actually happened is Gannon Stauch, and his poor little body was inside of a suitcase. And don't get me started on the crazy that is Leticia Stauch!
