Casey Anthony files for bankruptcy as she vows to 'keep fighting' legal issues

(CNN) -- Casey Anthony's fate keeps changing.
Two years ago, her murder trial for the death of her toddler riveted the country, ending with Anthony's dramatic acquittal. But she was convicted on four counts of lying to authorities.
On Friday, an appeals court threw out two of those convictions.
Now, the 26-year-old has filed for bankruptcy, citing almost $800,000 in liabilities.
And her legal struggles are far from over.
Bankruptcy motive questioned
Anthony sought Chapter 7 protection in a federal court in Tampa on Friday, soon after the appeals court ruling.
Such a filing is meant to allow one to do away with most existing debts and make a fresh start financially.
In the documents, Anthony says she owes almost $800,000 to about 80 creditors, and she has no income.
She is also defending herself against several civil lawsuits, including a defamation suit from Zenaida Fernandez-Gonzalez, who claims Anthony ruined her reputation.
In 2008, Anthony told an investigator the last time she saw her 2-year-old daughter Caylee was when she dropped Caylee off at Gonzalez's apartment.
Gonzalez's attorney, Matt Morgan, told CNN affiliate Central Florida News 13 he believes the bankruptcy filing is an attempt to postpone the case.
