A non-profit group said that it will sue Casey Anthony for the $100,000 it spent on the 2008 wild goose chase to find her missing daughter.  Anthony was acquitted on charges of killing her two-year-old child using duct tape and chloroform July 5.

The defense said that Anthony's child drowned in a swimming pool accident, prompting a cover-up by the family.  The prosecution maintained that Anthony drugged the little girl with chloroform and suffocated her using duct tape. 

Deleted internet searches were found on Anthony's personal computer for the terms how to make chloroform, neck-breaking, and self-defense.

Anthony faced the death penalty but got off with lying to investigators. Since Casey was on her best behavior while she was in jail, quietly writing letters about how hot her male fans thought she was, only another couple of weeks were added to her sentence.  Casey is expected to party like it's 1999 when she is released Sunday. 

The lawsuit was filed by Texas EquuSearch and is the second civil court filed against the young woman.  The first lawsuit was filed by Zenaida Gonzalez, a woman Anthony accused of kidnapping her child.  

A Florida jury found the 25-year-old not guilty of first-degree murder after Caylee's skeletal remains were found in woods near the Anthony family home.

The lawsuit said that Casey Anthony knew that her apparent 'cooperation' with the massive searches coordinated by TES created an appearance that she was a victim of law enforcement's unjust investigation and that she was a concerned mother seeking her missing child's return.
