ORLANDO -- Published reports said air tests have shown a human body was decomposing in the trunk of the Casey Anthony's car.
The tests were done by the University of Tennessee Forensic Anthropology Facility, which is better known as The Body Farm.
By testing the air inside the trunk of Casey's car, officials at The Body Farm said they were able to determine a body was decomposing inside.
A representative of the research facility talked with the Anthony family, including Casey, Wednesday night.
Afterwards, Anthony's attorney, Jose Baez, and Casey's father George were seen leaving the house.
Deputies won't confirm the results of the test, but said they did get lab results back from the FBI, and will talk with the State Attorney's Office on Thursday.
Meanwhile, despite the fact the family is denying a plea deal is in the works, Leonard Padilla said that's exactly what's being worked on now.
"And I thought by getting her out, she would cooperate. Not one word in that direction. Nothing. Nothing. So now with this immunity deal, I think it's a situation where she has to face reality. If she can, she might not have the ability to do that, and cooperate with the authorities, and if it was an accident, once they recovered the body, they will know."
In a 911 call, Cindy Anthony, Casey's mother, said her daughter's car did smell like a dead body, but later changed her story saying the smell came from a rotting pizza.
Investigators said they also found strands of hair, stains and dirt inside the trunk.
Padilla Having Second Thoughts
On Wednesday, Padilla, the high profile bounty hunter that helped get Casey out of jail, said he's having second thoughts.
On Aug. 20, he said within seven days he would find the missing 3-year-old alive.
However, after hundreds of pages of new documents were released in the case, Padilla said he no longer believes Casey's story that she left Caylee with a babysitter.
"(Do I feel that way now?) Probably not to be honest with you, because she hasn't given us a assistance whatsoever," said Padilla.
He said revoking Casey's bond is something to consider, but he's not positive that will happen.
Padilla does believe though the little girl is still alive.
Natalee Holloway’s Mother To Join In Search For Caylee
On Wednesday night, the Anthony family announced Beth Holloway will be joining in the search for the missing toddler.
Holloway is the mother of Natalee Holloway, who disappeared in 2005 during a high school trip to Aruba.
She has never been found, but it's believed Holloway is dead.
The Caylee family spokesperson Larry Garrison worked on the high profile case, and even co-authored a book on Holloway's disappearance.
