I *personally* believe that the body was dumped and there was no attempt at covering it up. From the reports, I get the feeling that this was "a dump job" where the perpetrator wanted to get rid of the body as soon as possible. I have no doubts that it will be ruled a homicide.
I tend to agree with you. Do you remember the details about the other girl who was taken from the general area and dumped? I have been searching but can't find the link...
