TAMPA, Fla. -

For sale to the highest bidder: Exclusive worldwide rights to Casey Anthony's "life story."

At least, that's what a bankruptcy trustee is seeking.

One man has already offered the bankruptcy estate $10,000 for the rights, but only so he could prevent anyone else (including Anthony) from profiting from the story, according to a motion filed Friday by the trustee.

That bidder's stated intent is to prevent any intellectual property from being produced that is based on Anthony's experience, including her acquittal in the death of her daughter, Caylee.

But, the trustee wrote, "due to intense public interest," he believes there will be more interest in the rights.

So he asked Judge K. Rodney May  to give potential bidders three weeks to bid in writing. If an additional bid is received -- accompanied by a 100% deposit covering the bid -- an auction would be held.

It's the trustee's job to seek to extract as much value as possible from the holdings of someone seeking to declare bankruptcy, with the proceeds going mostly to those who are owed money.

Anthony sought bankruptcy protection in January, claiming about $1,000 in assets and nearly $800,000 in liabilities, including $500,000 to her lead criminal defense attorney, Jose Baez.
