Whether or not this case was drug related, it is worth considering the murderer's motives. Why was Karlie killed?
To me, the killing occurring in Belanglo is not consistent with an out of control domestic violence killing but rather suggests premeditation.
It is awful to contemplate, but was Karlie tortured or beaten for information about missing money prior to her murder? Was her murder (and possibly Khandalyce's) punishment?
I am inclined to think there are more people involved than we know about.
A little behind and catching up on this thread.....
I'm with the notion of premeditation here too, whatever the reason.....imo the person who murdered Karlie wanted her murder connected to Belanglo as a red herring....no doubt in my mind. Sinister premeditated murder....moo.
