Casey Anthony's Lawyer Said She Killed Her Daughter, Claims Former Private Investigator

Former private investigator who worked on Casey Anthony's defense team claims she also had sex with her lawyer to pay her legal fees.

A former private investigator on Casey Anthony's defense team is making serious allegations about her trial attorney, Jose Baez, claiming he said his client was guilty of killing her 2-year-old daughter.

"Baez had told me that Casey murdered Caylee and dumped the body somewhere," said Dominic Casey, according to an affidavit filed in court relating to Anthony's bankruptcy case that was posted online Wednesday by several media outlets.

Casey also claimed in the 15-page affidavit that Anthony had sex with Baez as a form of payment for his legal services.

Baez vehemently denied all those allegations Wednesday.

“I unequivocally and categorically deny exchanging sex for my legal services with Ms. Anthony.  I further unequivocally and categorically deny having any sexual relationship with Ms. Anthony whatsoever.  I have always conducted my practice consistent with the high ethical standards required of members of the Florida Bar.  My representation of Ms. Anthony was no exception,” the attorney said in a statement obtained by

“Legal action is forthcoming,” Baez said.

Anthony was acquitted five years ago of killing her daughter, Caylee, whose body was eventually found in swamp near Anthony’s home.

The young mother’s sensationalized murder trial captivated television viewers around the world, and pitted Caylee’s grandparents against their grown daughter.

It was Casey Anthony’s mother, Cindy, who reported the child missing in 2008 after she hadn’t seen her grandchild in a month.

Anthony claimed the child had been kidnapped by a babysitter.

Casey’s affidavit claims that Baez told him that he “needed all the help he could get to find the body before someone else did.”

The former investigator for Baez said in the document that he had seen Anthony naked in Baez’s private office and that he had discussed it with Anthony who said she “had to do what Jose said because she had no money.”

He also contended that Anthony suggested casting blame on her parents and on Roy Kronk, the meter reader who made several calls to authorities saying he had found what looked like the remains of a child in a wooded area about half a mile from the Anthony home.

Authorities eventually discovered Caylee’s remains in the area that Kronk reported.
