ORANGE COUNTY, Fla. -- Over 1,000 new pages of documents were released Tuesday in the case against Casey Anthony. They include a statement that an FBI investigator saw an outline of a small body in the fetal position in Casey's trunk (read FBI document).

According to many of the emails among the documents released, the Anthonys’ private eye, Dominic Casey, was really looking for dirt on key people involved in the case, innocent people who have never been considered as suspects in Caylee's murder and he was looking for a conspiracy theory, too.

VIDEO REPORT: New Documents Released In Case

---

There are also new revelations in the new documents about the mysterious stain in Casey Anthony's car trunk. FBI investigators say the stain is shaped like a child's body in the fetal position (read it). The FBI says the child's back, bottom and legs could be seen most clearly.

WFTV legal analyst Bill Sheaffer says it adds to the hair and air in the trunk showing evidence of decomposition.

“Why is a child's body gonna be in the trunk of that car dead or alive? It's significant that the child's body was in the trunk of that car,” Sheaffer said.

The new records also include dozens of emails exchanged between Cindy Anthony and private investigator Dominic Casey (see D. Casey documents), which focus on digging up dirt on key people involved in the case.

One of the most bizarre emails accuses Casey's ex-fiance's father, Richard Grund, of having weird religious beliefs that might lead him to human sacrifice rituals. Dominic Casey was also focused on finding connections between Grund and meter reader Roy Kronk, who found Caylee's remains near the Anthonys' house in December, and was investigating Kronk's relative and the relatives of Casey's ex-boyfriend, Ricky Morales.

Cindy said finding a connection between Kronk and Grund would be "huge." She wrote, "I want him to go down for this if he is involved. I have people that can fly under the radar and make it happen."

“There's always been a sense of desperation about the defendant's case, especially because Casey has made so many inconsistent statements,” Sheaffer said.

Eyewitness News also learned that Dominic Casey expects to be paid by the Anthonys, according to their contract, and that he had offered Casey's brother Lee an internship. Dominic Casey’s emails are marked "privileged and confidential,” but they are now public record.

Among the documents was a chart that showed the people the Anthony family considered "threatening" (see chart) and weren't invited to Caylee's memorial service. They include former bounty-hunter Leonard Padilla, Casey's ex-fiance Jesse Grund, ex-family spokesman Larry Garrison, Zenaida Gonzalez, the woman who's suing Casey, talk-show host Nancy Grace and WFTV’s own Kathi Belich, who's uncovered more about the case than anybody,

DUCT TAPE CONTAMINATED

Duct tape found on the mouth of slain toddler Caylee Anthony was contaminated by an FBI evidence examiner, raising questions about how it will be used in prosecuting the 2-year-old girl's mother for the murder.

The disclosure of the contaminated duct tape was among hundreds of pages of evidence released Tuesday by the State Attorney's Office in Orlando.

Danielle Tavernier, a spokeswoman for the State Attorney's Office, says she cannot comment on the documents.

CINDY WANTED TO KEEP SEARCHING FOR CAYLEE

One of the most bizarre revelations is that months after the Anthonys held Caylee's funeral service, Cindy still wanted her private investigator to search for a live Caylee, and Cindy and her private investigator exchanged possibly hundreds of emails concerning how they could dig up dirt about some of the key people in the case, including bounty hunter Leonard Padilla, meter reader Roy Kronk and Jesse and Richard Grund.

The Anthonys' private investigator, Dominic Casey, emailed photos to Cindy to show to Casey of possible Zenaidas and there were a lot of computer searches for Zenaida Gonzalez, the name of the woman Casey says disappeared with Caylee.

Cindy also sent a photo of a child (see photo) to Dominic Casey around three months ago, in early July, claiming it looked like an "older Caylee" and the lead supposedly had a connection to Puerto Rico.

Cindy also wanted him to check on another tip in April, three months after Caylee's memorial service, that Caylee was actually in Bungalo 19 at a California address.

“That doesn't do her any good and it doesn't do the defense any good. That's going to affect her credibility should the defense attempt to use her at trial," Sheaffer said.

One of Cindy's emails might come back to haunt her daughter in the Zenaida Gonzalez defamation lawsuit. Cindy told one of the sheriff's investigators last October that private eye Dominic Casey was not working for the defense team, but recently the private eye testified under oath that he was in his attempt to avoid being questioned under oath by Zenaida's attorneys.

In addition to the Dominic Casey documents there are hundreds of pages of FBI investigative reports and DNA testing (read FBI reports), and the transcript of an investigative interview with Casey Anthony's former friend Annie Downing (read transcript).

The FBI investigative reports include a slew of DNA reporting on a variety of evidence in the case and the DNA paternity results (see paternity results) for Casey's ex-fiance, Jesse Grund.

Also among the 1,000 pages released Tuesday are detailed product specifications for Henkel Duck brand tape (see product specs), the brand of tape believed to have been covering Caylee Anthony's mouth when her remains were found. The same brand of tape was also found in the Anthony home.

BOOK ABOUT CASEY CASE COMING OUT SOON

You can now read up on the case against Casey Anthony through a new book hitting the shelves in November.

In "Mommy's Little Girl," true crime author Diane Fanning poured through thousands of public court documents to deliver Casey's story and a picture of her family life in novel form.

Casey is presumed innocent until proven guilty in a court of law, but the author also theorizes about why Casey might have killed Caylee.

STATE FILES RESPONSE CHALLENGING DEFENSE

Prosecutors are challenging the defense team in the case against Casey Anthony. The prosecution filed a response to a defense motion Tuesday asking Casey's attorney, Jose Baez, and his team to prove the state kept defense experts from having adequate access to the site where Caylee's remains were found.
