Why would a killer leave a body out in the open, where it will definitely be found?
Serial Killer - doesn't fit DW
Killer in a Hurry - doesn't fit DW
Friend/Family - for "closure" (not to mention any potential insurance money)- does not fit DW
Westerfield could have buried the body anywhere, burned all the evidence (including the MH).
Even if it were a kidnap for ransom gone awry, I bet the perp would hide the body.
Don't know, agree, agree, agree, agree, agree.
