New court papers suggest discord between a private investigator and the attorney representing Casey Anthony, the Florida woman acquitted in 2011 of her daughter's murder, according to media reports.

The investigator, Dominic Casey, said in court deposition documents related to Casey Anthony's Chapter 7 bankruptcy filing in Florida that Jose Baez, the attorney who represented Anthony, told him that Anthony admitted to killing her daughter, according to reports in the Orlando Sentinel, Fox News, and PeopleMagazine. The documents are filed with U.S. Bankruptcy Court, Middle District of Florida, Tampa Division, and are dated April 25, 2016.

Casey also claimed in the deposition that Baez had a sexual relationship with Anthony, a claim that Baez vehemently denies.

"I unequivocally and categorically deny exchanging sex for legal services with Ms. Anthony," Baez wrote to People. "I further unequivocally and categorically deny having any sexual relationship with Ms. Anthony whatsoever."

Casey worked with Baez in 2008 after Casey Anthony was arrested for child neglect following the disappearance of her 2-year-old daughter, Caylee Anthony, on July 5, 2011. Dominic Casey's affidavit is dated Dec. 15, 2015.

On July 26, 2008, the investigator claimed, Baez told him that Anthony murdered her daughter and "dumped the body somewhere and he needed all the help he could get to find the body before anyone else did."

Dominic Casey also wrote of an incident in which he arrived unexpectedly at Baez's office and found Casey Anthony there, naked. Anthony ran out of Baez's private office through a conference room and into a hallway, Dominic Casey wrote. It was not an isolated incident, he wrote.

Casey "told (Anthony) that she cannot allow (Baez) to continue engaging in this behavior," the investigator wrote in the affidavit. "Casey told me she had to do what Jose said because she had no money for her defense."
