Last week, you heard the state's case against accused killer Casey Anthony, a young mother who wanted freedom more than responsibility.

A pattern of lies, a trunk that smelled of decomposition, and a toddler's remains found less than half a mile from home.

According to prosecutors, the story was clear.

Casey Anthony killed her daughter so she could live a Bella Vita,

a beautiful life without a child standing in the way.

The timeline was laid out, the lies stacked up,

and the forensic evidence, they argued,

seemed to point in one direction.

But this week, the defense stands up and

tells a very different story. They don't deny the lies. They don't pretend the behavior looks good.

They don't argue that Casey handled things the right way. And they don't even claim that someone

else is responsible for her child's murder.

Instead, they tell jurors Kaylee wasn't murdered at all.

They say Kaylee's death was a tragic accident inside the family home.

There was a moment of panic followed by a split second mistake. And everything that followed, the lies, the strange behavior, the silence, was not about

partying or freedom.

It was about fear.

According to the defense, this story didn't begin in June of 2008.

It began years earlier.

And in this version of events, the man who sat in court as a grieving

grandfather is no longer just a witness.

He becomes the center of the storm.
