Casey Anthony may be a free woman, but authorities say her case wasn't free - and it was her fault the search for little Caylee kept going.  And now the judge presiding over her trial has come up with just how much the Florida mom must repay.

FOX News Radio's Chris Hoenig reports:

At her sentencing back in July, Judge Belvin Perry let Casey Anthony know she could be paying a hefty price for lying to cops.

"I will reserve jurisdiction to determine the cost of prosecution and investigation."

Now, Judge Perry has come up with that figure: $97, 676.98.

Anthony was acquitted of murder in the death of her two-year-old daughter, but found guilty of lying to police about Caylee's disappearance.  It's the investigations caused by those lies that she's on the hook for.

Editors Note: Judge Perry did deny the State's request to charge Anthony for costs related to her prosecution on the murder counts.  She has already filed paperwork that she's indigent, and is serving probation somewhere in Florida.
