Unreal. How is she out on bond? There are so many loose ends here too. I wouldn’t be surprised if others were involved.
Mostly, the court should look at family, employment, track record of appearing in court, financial status. The only thing that would mark her as a flight risk is finances as she is wealthy enough to run away.
However, if she does run she'll loose free access to the majority of her fortune which makes her less likely to run.
How would anyone be a flight risk if you exclude these factors.
Fear of a possible conviction is pretty much the only reason why anyone would give up their current life to flee.
