Give her your unrelenting support...and listen, listen, listen! Then listen to her some more. Help her find a new job and living arrangements, then show up on her doorstep on move day to handle everything.
Just my $0.02.
I am sorry to hear this, I live in Saint Louis, so I can definitely relate to the crime. The worst thing is that even if she was off of work, Illinois does not even allow CCW. My prayers are with you and your daughter's safety.
