A Florida woman who became a cause celebre for civil-rights activists after she received a 20-year prison sentence for firing a warning shot has been released on house arrest this week as she awaits another trial.

Marissa Alexander's supporters said that she was at home for Thanksgiving with her children Thursday after she was released on $200,000 bond following a judge's ruling on Wednesday.

Alexander's sentence, which she received after she unsuccessfully invoked Florida's "stand your ground" law, came to prominence after the nation was gripped by the Trayvon Martin case, in which George Zimmerman was acquitted of murder after shooting the unarmed 17-year-old.
