Inside the package are five dossiers, including ones on Bruce Thompson, Andrew Hembree, and Mark Schwartz. Each one is over one hundred pages long, complete with recent surveillance photos, bank statements, contents from their personal computers, and, most importantly, sealed juvenile records. There's a smaller dossier on the late Tom Wyatt, even though Cora didn't ask for it. Caroline included it because in discovering the criminal records, she found his name in conjunction with the other three on several separate occasions, along with one other name.
Caroline has flagged and highlighted the notes from a group therapist as particularly important. In them, he notes that none of the boys have committed any serious crimes at this point in their lives, but he's worried that the potential is there, simply because they all seem to feed off of each other. He goes into great detail about the group dynamic between Thompson, Hembree, Wyatt, Schwartz, and a fifth boy he identifies as their ringleader: Jeremy Case. The therapist is not optimistic about Case's future.
Caroline has also included a helpful note here via Post-It:
Jeremy Case is in your criminal psychology class. He sits three seats behind you.
