A woman who claimed to have incurred more than $300,000 in medical bills after a truck backed into her car walked out of a DeKalb County courtroom with nothing after defense testimony showed that she swapped out the scarcely damaged car before police arrived with another that had been wrecked years earlier.

Adding to her credibility problems was testimony from her doctors that she’d been complaining about back pain for years even though she said in depositions that she’d never been in a wreck or suffered any injuries, said defense lawyer G. Lee Welborn of Marietta’s Downey & Cleveland.
