By the time Caylee's body was found six months after she disappeared, it was so badly decomposed that the cause of death was listed as homicide by undetermined means.
Casey Anthony was found not guilty of murder, but guilty of lying to police four times.
Last week, juror No. 3, Jennifer Ford, told ABC News exclusively that she believed prosecutors could have won a guilty verdict if they had brought a lesser charge than first-degree murder, which carried the possibility of the death penalty.
Ford said jurors were crying and "sick to their stomachs" over the verdict, which has prompted angry demonstrations and fear that the safety of Casey Anthony and others involved in the trial might be in jeopardy.
On Thursday, the Orange County, Fla., judge in the case refused to release the names of the jurors who acquitted the Florida mom of killing her daughter for fear that people upset with the verdict might harm them.
Despite the emotional public reaction, jurors have described taking a detailed, analytical look at the evidence and finding it lacking despite whatever personal reactions they may have had about the Anthony's guilt or innocence.
For instance, the foreman told van Susteren that jurors found key prosecution evidence involving duct tape and chloroform to be ambiguous, that they thought it plausible that Caylee could have drowned accidentally, as the defense suggested, and didn't think it was proven that Caylee's decomposing body was in the trunk of the Anthony family car or, if it was, who put it there.
Though jurors were suspicious of George Anthony, he added, they did not put much stock in defense claims he may have been a molester.
"There was no evidence to back that, so I really couldn't take that into consideration," the juror said. "That was not a discussion of ours when we got into the deliberations, as far as the sexual abuse."
"What was," he added, "was George Anthony's actions and his demeanor and the way that he presented some things up there on the stand.
"I really thought that George had very selective memory in the whole regard," he said. "I thought that George, at times, could remember some things as vividly as if things happened the day before."
At other times, he said, George Anthony's memory seemed to grow fuzzy. He cited Anthony's difficulty remembering details on how tape ended up on a gas can, discrepancies in testimony between him and his alleged mistress, and his behavior at a tow yard, where he may have feared there could be a body in a car trunk but simply drove the car home.
"It raised questions," he said. "It really did."
Asked if jurors thought it was possible George Anthony helped cover up a death, was involved in an accidental death or was "a murderer," the juror said, "All three. We don't know. ... The suspicions were raised" in the jury room.
In compliance with Florida state regulations, the juror notes will be collected and destroyed, court spokeswoman Karen Connolly Levey told ABC News.
