Casey Anthony is facing a $100,000 law suit for lying to private investigators during a search for her missing daughter Caylee Anthony. The missing persons agency, Texas Equusearch, is asking a court to make Anthony pay for the search, which cost the agency significant cash donations and volunteer hours.

According to documents filed in an Orange County, Florida court, Texas Equusearch is a highly-regarded non-profit organization dedicated to the search and recovery of missing person in cooperation with law enforcement.

The company is funded through donations, which Texas Equusearch is claiming Casey Anthony wasted during the manhunt for a girl who Anthony knew was dead.

Cindy Anthony hired TES when Casey Anthony told her mother that two-year-old Caylee was abducted by the babysitter. After that was proved false, TES engaged in a thorough search for the girl, and talked with Casey in Florida on numerous occasions. Casey told the investigator, who was apparently very decorated and highly lauded, that young Caylee was still alive.

It was revealed in court, however, that Casey Anthony was well aware of her daughter's death. TES is claiming that its search, which cost them over $100,000 and involved more than 4,200 volunteers in 13 states and 10,000 hours of searches, could have been avoided if Anthony hadn't lied to them.

Tragically, TES claims that they couldn't assist 15 other families with missing children because they were too busy looking for Caylee Anthony.

The case will be examined by the Circuit Court of the 9th Judicial Circuit for Orange County.

Texas Equusearch has done 1,200 missing persons searches in 42 states and a number of countries. They have found more than 300 people. The company never charges the families for the searches. That is, until now.
