While missing persons agency Texas Equusearch was searching for Casey Anthony's abducted daughter Caylee, they were forced to turn away 15 other families with missing children.

The investigation company, TES, has filed a suit against Anthony, claiming the mother let the agency spend more than $100,000 on a manhunt she knew was futile.

TES is a private, non-profit that tries to help any family that needs it. Cindy Anthony, little Caylee's grandmother, contacted the Texas agency when the two-year old went missing. The company, which has a high success rate and has received awards from people like George W. Bush, devoted so much money and man power to the Casey Anthony case that they were unable to assist other families whose children really were missing.

It certainly wasn't fair to anybody that was involved and wasn't fair to the families that really needed us, lead investigator Tim Miller told an Orlando Fox affiliate.

According to court documents filed in Orange Country, Florida, Casey Anthony repeatedly lied to Miller for months. TES is funded through donations, which Texas Equusearch is claiming Casey Anthony wasted during the manhunt for a girl who Anthony knew was dead.

The search for Caylee, who was actually dead on Anthony's property, cost TES over $100,000 and involved more than 4,200 volunteers in 13 states. The search logged tens of thousands of man-hours, all of which could have been avoided if Anthony hadn't lied, over and over.

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.
