The story's been reported on CNN.

New facts: The guy involved
had test fired the pistol against a similar book without the bullet going through. The story doesn't say if he did it at a 1 foot distance, though.
The lady was definitely against trying this stunt.
As for her current status:
Perez faces up to 10 years in jail and a fine of up to $20,000 if she is convicted of the manslaughter charge against her. She has been released on bail, and as a condition of her release she cannot possess firearms, needs to notify her attorney of her whereabouts and has to wear a GPS monitor, according to court documents. She will be back in court on July 5.
Given that she's free on bail I suspect the court is going to be quite lenient with this 7 months pregnant young lady. I hope so, anyway.
