I thought it was connected to her friend.
Having your facebook filled with csi murder games might not mean anything at all but at the same time it might give a screwed up mind sick ideas.
I could be wrong but I heard that on the fb page of the friends girlfriend she had a status saying.. "can i get away with it" or something down that line, later when I checked her facebool I only saw a lot of crime & murder game shares.
The friends girlfriend was also to be said gone camping the day it happened & returned home when samantha was reported missing to be with her girlfriend
For now, it looks like a 22 year old male is the focus of the investigation:
"He is being questioned by police and could appear in court tomorrow."

That said, if he doesn't have a car, then someone helped him dispose of Samantha.
