In his 2013 book Presumed Guilty, attorney Jose Baez said he was still "haunted" by the mystery of who killed two-year-old Caylee Anthony and left her body in the woods in 2008. "This fact disturbs me greatly," he wrote. "It's the one fact that will never change. You don't do that to a baby. Whoever put Caylee there, I curse you."

A few years later, however, the case haunted him in a different way. That's when a private investigator had the media questioning how Casey Anthony paid for her lawyer fees when she didn't have a job. Baez and Anthony certainly seemed close, but in an affidavit, Dominic Casey said they were even closer than they apperanced. He said the Florida mother paid Baez with sexual favors.

Casey made the claims in a 2016 affidavit related to Anthony's bankruptcy case. In that 15-page document, he said Anthony had a sexual relationship with Baez before she went on trial for Caylee's murder. In fact, Casey claimed he saw Anthony naked when he arrived unannounced at Baez's office, as People reports.

Furthermore, according to the Daily News, the private investigator said in the same affidavit that sex is how Casey Anthony paid for her lawyer. He claimed he heard Baez tell her she owed him "three b— jobs" after he canceled a media interview at her behest. "Casey told me she had to do what Jose said because she had no money for her defense," he wrote.

For his part, Baez said that the claims were all fictitious and that he'd be pursuing legal action. "I unequivocally and categorically deny exchanging sex for my legal services with Ms. Anthony," he said in a statement to People. "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."

Additionally, Casey wrote that Baez told him of Anthony's guilt. "Baez told me that Casey [Anthony] had murdered Caylee and dumped the body somewhere and he needed all the help he could get to find the body before anyone else," he said.

In his denial of the sexual relationship claim, Baez also cited the private investigator's history of bombshell allegations. "This libelous claim is in line with many other outrageous claims and theories that this individual has advanced regarding the Casey Anthony case," he wrote.

In 2011, a jury found Anthony not guilty of murder but guilty of providing false information to law enforcement. Nearly two weeks later, she was released prom prison with credit for time served.
