I've thought from the outset that Isabel's parents had probably instructed family members, friends, teachers, etc. not to discuss the case in the media. I'm sure that many people outside of the family circle have since been interviewed by LE and/or the FBI, and there is certainly no way that the parents could interfere with this aspect of the investigation. :moo:
But I don't mean discussing the case . . I just mean teachers, friends, making a statement of what she was like, and how they miss her . . (or SOMETHING!). But as you say, the Coach can't coach everyone!
