This should stay in adult court. They are going to try every double standard in the book to get in into juvenile court. Young, female, sympathy, insanity.
If it goes there we will never hear what they get for sentencing. And they at max will be free at 18, if not earlier.
If the insanity defense were to work, they would be in a mental treatment center for at least as long as they would be in an actual prison, and possibly longer. If it were to somehow work, no getting out at 18 for either one of them.
