Perhaps that is true in regards to pending murder charges, but LE found enough evidence of multiples crimes to charge Casey with:
1.fraud- caught on video tap, and I am sure the cheques have since been dusted for prints, not to mention her DL used as ID
2. child neglect - not calling the police when your child is missing for approximately a month
3 - obstruction - having statement after statement disproved and invalidated by LE
There may not be enough evidence yet of murder, but I doubt Casey can be proven innocent on any of the charges listed about
ergo - Casey is not innocent
And a judge set bond to the tune of half a mill. That says something also.
