If you've seen the stills you would understand that if you can't ID him, you probably won't be able to ID her.
They know each other, and most likely are siblings.
It is bad enough that his picture has been put on the news. His life is over.
There is literally no reason to make this worse by broadcasting her face.
How many of us went and looked at those pictures which we would never have seen if not for the police putting his picture in the news? How many more people do you want to see this girl being abused? Again, nothing is gained by the police putting her picture in the public domain as an abused child. THAT IS WHY THEY NEVER DO IT.

It isn't in HER best interest, and that should be what matters most.

How can they possibly not have gotten tips yet IDing him? And yet they haven't asked the news sites to pull the comments which led us to see things we never wanted to see.
Her face would be public domain for eternity as a victim, to EVERYONE , not just the perverts of 4chan, etc.
