'Our Hearts Are Breaking': New Photos of Caylee Anthony

But days passed after Casey's release from jail, and there were no new revelations from the young mother.

"She has no display of emotions," Padilla said. "She's completely in control."

"She's in a no-win situation," said her attorney Jose Baez. "If she cries in front of the cameras, people are going to call it crocodile tears. People say that she's not showing emotion, but that couldn't be further from the truth. When I'm with her when we speak, many times she's broken down."

There was more reason to be upset just a week ago, when Casey was rearrested on charges of petty theft, accused of stealing a checkbook from a friend. But within hours of her return to jail, police stated that new tests on the trunk of the Anthony's car had revealed even more tragic -- and seemingly conclusive -- evidence.

"There was hair resembling Caylee's in the trunk," said Belich. "There was a stain in the trunk. And we know that the FBI DNA test showed that the stain and the hair came from Caylee, and that Caylee is, in fact, dead."

In the last 48 hours, new information has emerged. Sources close to the investigation say that Casey's laptop computer had been used to search the Internet for information about chloroform -- traces of which were found in the trunk of the car.

"It's not evidence until it's been admitted in court, until it's had and passed the rigors of cross examination," said Casey's attorney Jose Baez. "It's not evidence. So it's just an accusation. "

'It's Very Sad'

Despite all the speculation, the most serious charge against Casey Anthony is child neglect. But why did she wait so long to report her child was missing?

"She's a remarkable young woman in the sense that ... the best way I could describe her is she's a steel magnolia," said Michael Walsh, a member of her defense team. "No matter what anybody thinks, Casey Anthony is adamant. She did no harm to her daughter. She believes her daughter is alive. She believes her daughter's going to be found alive and well."

Casey's defense team also notes that while her actions may seem strange, there are good explanations for them, including why she waited 31 days to report that Caylee was missing.

"It's obviously the million-dollar question, and it's a question we'll answer when we're in court," Walsh said. "There's a very compelling reason, and we'll play that reason out in a court of law where it counts."

For the family and friends, the search for Caylee continues.

"You look at those photographs of her. She's adorable," said WFTV's Belich. "And you see, you know, pictures with her grandmother, she loved that little girl ... your heart goes out to them. It's very sad."
