Jurors in the Casey Anthony murder trial in Florida were expected to hear a tenth day of testimony Saturday.
She's charged with first-degree murder in the death of her daughter, toddler Caylee Anthony, almost three years ago.
On Friday, jurors saw jail-house videos of Anthony talking to her parents about her missing daughter.
Prosecutors say the more she talked, the more she lied.
And criminologist and legal analyst Casey Jordan agrees, telling "Early Show on Saturday Morning" co-anchor Rebecca Jarvis that Anthony's lying was "off the charts."
Mike DeForest, of CBS Orlando, Fla. affiliate WKMG explained that the tapes were made as the search was intensifying for two-year-old Caylee.
In one portion played for the jury, Anthony insisted to her mother, Cindy Anthony that, "In my gut, I know she's (Caylee's) still OK. I can feel it, Mom."
Prosecutors say the tapes show a pattern of deception.
"Someone just said that Caylee was dead this morning, that she drowned in the pool," Cindy told Casey. "That's the newest story out there."
"Surprise, surprise," Casey responded.
"We need to have something to go on," Cindy said.
"Mom," came the reply, "I don't have anything. I'm sorry. I've been here a month. I've been here a month today."
Four months after the recording was made, Caylee's body was found in the woods.
Anthony was charged with murder.
Ironically, the swimming pool story is at the heart of her defense. Her lawyer says Caylee did drown, but it was an accident.
Another key to Anthony's defense is that she'd been repeatedly abused by her father, George Anthony.
But in the jailhouse tapes, the relationship between father and daughter seems anything but hostile.
George is heard saying to Casey, "Good morning, Beautiful, I love you."
"Hi, I love you too. ... I can't say this enough to you," an emotional Casey said. "You've done everything you possibly can. And you are the best father and by far the best grandfather I have ever met. I mean that with all my heart."
"If I could switch places with you this second," George said, "I'd do it. I would do it."
"I know that."
"Believe me, I would."
"You know how much I love you, how much I've always loved you," Casey said. "You'll always be my buddy, even besides my dad."
But Jordan, the criminologist, told co-anchor Jarvis Anthony's departures from the truth were "not just lying. It is lying that is off the scale. We call it ( a syndrome of lying) where it's so pathological, so beyond the pale. She lies when she doesn't need to lie.
"We had the 31 days of bizarre behavior, partying behavior (by Anthony, while Caylee was missing). But now (in these tapes), the jig is up. She's in holding, she's in a jail cell. Her parents are begging her to help them find their missing granddaughter. And all she does is keep saying lie after lie after lie -- 'In my gut, I know she's alive' when, in fact, even under the defense theory of the drowning, she does know her daughter is dead. Why doesn't she just come forward at this point, while she's in jail, while everyone is begging her for help, and say that the baby drowned? But she doesn't do this. She keeps covering it up."
Can the damage to the defense's case be overcome?
"Most people agree that she's eventually going to have to take the stand," Jordan observed. "But the biggest thing is that they are building, chronologically, this web of lies."
If forensic evidence the jurors hear "meshes and it looks like every lie she told was to cover up evidence of a homicide," Jordan continued, "then the prosecution's case is really going to gel."
The tapes of the conversations with George Anthony should also change the dynamics of the case, Jordan says, because, "The defense has put all its eggs in had one basket with regard to explaining Casey's bizarre behavior -- her lying, her covering up, her inability to tell the truth -- is due to the abuse at the hands of her father. Now, this came out in opening statements, which is not evidence, at all. But it's the Sword of Damocles hanging over the jurors' heads. Now that they see these tapes of Casey telling her father he's a wonderful father. She loves him. He's a great grandfather, her buddy -- this really raises questions -- is she such a liar that she's made up the entire story of abuse, because the evidence in the tapes indicates that she has a good relationship with her father. Maybe contentious in a father/daughter way. But, would a girl who was abused so beyond the pale that she can't tell the truth about her own daughter's drowning really be speaking this way to her father this way in jailhouse tapes?"
Jordan says Anthony doesn't have to testify but, "All the analysts are agreeing that her attorney has put so much out there that she has got to take the stand to explain her position. To argue that her father sexually abused her, to explain her behavior in the 31 days, to explain her pathological lying. But what she has to do is say, 'Yes, I have lied about everything in the past. But now, for the first time ever, I'm telling the truth.' Is she good enough, if you don't believe her -- is she good enough an actress to convince this jury?"
