You know, I was thinking along the lines of the resources she has wasted. But, given the idea that the families are very well off, they have probably paid plenty into the police department thru taxes, etc.
I would rather see the families come forward and offer restitution than see more resources wasted in pursuing criminal charges.
No one made the police start looking right away after she was reported missing. They made that decision against normal operating procedures.
It was the lying that should bring charges.
