Baez had called in six experts, including a forensic pathologist, an anthropologist and an entomologist in preparation to examine the scene, but had to fly them out before the chance was given for them to examine the evidence.
On Wednesday, the police brought in their own entomologist and anthropologist.
The man who found Caylee's remains made three calls tipping officials off to the area in August, Orange County Sheriff's Office spokesman Angelo Nieves said in a news conference Thursday.
Police believe utility worker Ray Kronk, 46, returned to the area last week "out of curiosity." He is not a suspect in the case, and police do not know if he had any prior association with Caylee's mother, Casey Anthony, who is being held on murder charges, Nieves said.
"This is just a decent citizen," Padilla said. "He sounds credible. He doesn't sound like he's making this up."
"His participation in this matter is strictly as a concerned citizen with a sharp eye, good instincts and perserverance," said Kronk's lawyer David Evans in a news conference yesterday. "He has no connection to this case, to the Anthony family or any of the proceedings that have gone on before."
Kronk called in a tip on Aug. 11 but only told police the general area where he saw a gray and black bag and did not meet the responding detective, Padilla explained. The detective did not find anything suspicious and cleared the area. Kronk called again on Aug. 12 and 13, at which point police returned to the scene but again did not find anything to raise their suspicions.
Padilla told ABC News that police are investigating the "thoroughness" of the response, but said the area had a significant amount of water flooding many parts.
"We're trying to make sure -- is it possible that we missed an opportunity to locate these remains back in August?" Padilla said.
The case began with an emergency call from Casey Anthony's mother, Cindy Anthony, in mid-July.
On the tape, she is heard frantically telling emergency operators, "I can't find my granddaughter. ... There's something wrong. ...I found my daughter's car today and it smelled like there's been a dead body in the damn car." Casey Anthony then got on the phone and reported she may have a missing child.
Cindy Anthony later retracted that statement, saying that the smell in the car could have been from garbage.
As investigators would quickly learn, this would only the be first of many twists and story changes in the curious case. CLICK HERE for a timeline of the case.
Since their investigation was launched on July 15, some Orange County officers have become well acquainted with the frustrations of following leads based on incomplete information, half-truths and what one officer said were "smoke bombs."
In the original version of events, Caylee's mother reported her missing to police, saying she had dropped the child off at a babysitter's house on June 9. When she went to pick the child up, both the child and the babysitter had disappeared.
Casey's parents both corroborated the story until a bond hearing on July 25 when Cindy Anthony said that the last time she saw the child was not on June 9, but on June 15, and that she had just been confused.
When police questioned Casey Anthony about her daughter prior to her arrest, they say Anthony misled them multiple times.
