Yes - maybe it is random.Here is a double homicide in a rural area that had some similarities.
In this case it was a father and daughter who were robbed by meth heads and then killed supposedly for fear of being identified.
Given all of the meth arrests in the area, I think this sort of scenario is a real possibility.
In this old case, they bound the victims probably because the perps were unarmed. They robbed them and then used the victim’s gun to shoot them later.
ETA such a scenario could explain why a gun was possibly left at the scene and also why someone would be bound but then also killed. Finally it could explain the uptick in meth arrests post double homicide.
