It is California so you have to assume he's probably going to the slammer and her family will sue his estate and win his house and car and whatever savings he might have. After all, it wasn't their daughter's fault she broke into the man's house.
Her accomplice will probably sue for mental anguish and win as well.
I can tell you by personal experience that merely being
charged with a crime is a very, very expensive proposition. That is why a Grand Jury is so important. If the charges are frivolous or the case is shaky, then the Grand Jury should probably err of the side of the accused and not return a true bill. When I was a Grand Juror, that was my standard. In this case, from what I know at this point, I might not return a true bill.
Don't want to get shot? Don't break into a house belonging to someone else, and if you do, don't physically attack the owner. The fact that she was apparently headed away from the owner is troubling, but as far as I know, she was moving to secure a weapon to continue the attack on an 80 year old.
If I was a juror on a civil case, I would have limited sympathy with the woman's family. Raise your daughter not to break into people's houses. I'd probably deny their complaint and vote to hit the family up for the court costs. There may be facts I am unaware of at this point that would change my mind, but as of now, that is how I see it.
