Casey Anthony not guilty of murder, manslaughter

Updated 3:01 p.m. ET

ORLANDO, Fla. - Casey Anthony was found not guilty Tuesday of killing her 2-year-old daughter in a case that captivated the nation as it played out on national television from the moment the toddler was reported missing three years ago.

Anthony, 25, wept after the clerk read the verdict, which jurors reached after less than 11 hours of deliberation over two days. She was charged with first-degree murder, which could have brought the death penalty if she had been convicted.

Instead, she was convicted of only four counts of lying to investigators looking into the June 2008 disappearance of her daughter Caylee. Her body was found in the woods six months later and a medical examiner was never able to determine how she died.

She will be sentenced by the judge on Thursday and could receive up to a year in jail for each lying count.

Still, the outcome was widely viewed as a surprise. An unnamed former member of the defense team told CBS News correspondent Troy Roberts that she never believed Anthony was innocent of the crime, but that her lawyers were trying to ensure that she avoided the death penalty.

After the verdict was read, Casey Anthony hugged her attorney Jose Baez and later mouthed the words "thank you" to him. Prosecutor Jeff Ashton, meanwhile, shook his head in disbelief.

Anthony's parents left the courtroom without speaking to her as the judge thanked the jury.

"While we're happy for Casey, there are no winners in this case," Baez said at a news conference after the hearing. "Caylee has passed on far, far too soon and what my driving force has been for the last three years has been always to make sure that there has been justice for Caylee and Casey because Casey did not murder Caylee. It's that simple. And today our system of justice has not dishonored her memory by a false conviction."

Anthony's attorneys claimed that the toddler drowned accidentally in the family swimming pool, and that her seemingly carefree mother in fact was hiding emotional distress caused by sexual abuse from her father.

Prosecutors contended that Caylee was suffocated with duct tape by a mother who loved to party, tattooed herself with the Italian words for "beautiful life" in the month her daughter was missing and crafted elaborate lies to mislead everyone from investigators to her own parents.

Captivated observers camped outside the courthouse to jockey for coveted seats in the courtroom gallery, which occasionally led to fights among those desperate to watch the drama unfold.

Anthony did not take the stand during the trial, which started in mid-May. Because the case got so much media attention in Orlando, jurors were brought in from the Tampa Bay area and sequestered for the entire trial.

Baez conceded that his client had told elaborate lies and invented imaginary friends and even a fake father for Caylee, but he said that doesn't mean she killed her daughter.

"They throw enough against the wall and see what sticks," Baez said of prosecutors during closing arguments. "That is what they're doing ... right down to the cause of death."

He tried to convince jurors that the toddler accidentally drowned in the family swimming pool and that when Anthony panicked, her father, a former police officer, decided to make the death look like a murder by putting duct tape on the girl's mouth and dumping the body in woods about a quarter-mile away.

Her father firmly denied both the cover-up and abuse claims. Prosecutor Jeff Ashton told the jurors no one makes an innocent accident look like murder.

"That's absurd. Nothing has been presented to you to make that any less absurd," Ashton said. He also spent significant time reminding jurors about forensic evidence that he said links Anthony to her daughter's death, including the smell and chemical signature of decomposition in her car.

Lead prosecutor Linda Drane Burdick concluded the state's case by showing the jury two side-by-side images. One showed Casey Anthony smiling and partying in a nightclub during the month Caylee was missing. The other was the tattoo she got a day before her family and law enforcement first learned of the child's disappearance.

"At the end of this case, all you have to ask yourself is whose life was better without Caylee?" Burdick asked. "This is your answer."

Prosecutors hammered on the lies Anthony, then 22, told from June 16, 2008, when her daughter was last seen, and a month later when sheriff's investigators were notified. Those include the single mother telling her parents she couldn't produce Caylee because the girl was with a nanny named Zanny — a woman who doesn't exist; that she and her daughter were spending time in Jacksonville, Fla., with a rich boyfriend who doesn't exist; and that Zanny had been hospitalized after an out-of-town traffic crash and that they were spending time with her.

The jury was chosen from the Tampa Bay area because of pretrial media coverage, and had been sequestered in an Orlando hotel.
