If this was a sting, I can just hear the instructions they gave him:
Okay, Mike, here's what we want you to do. Terri likes attention, so give her attention. Let her know you're interested, nevermind the fact that you went to high school with Kaine and she's suspected with hurting/murdering a child. Don't even think about that. Just make her think you want her, yeah. That'll work.
Oh, and she loves using her cellphone, so if she sexts you, then sext her back and keeping it going for as long as possible. We wants pics and text. No, really. We do.
And those documents, the RO. She'll have that. Even though it's clearly against the law, we're advising you to make sure you get a look at them, and oh, show it to a friend or two as well. We know how it sounds or looks, but we're LE telling you this, so it's okay to do. You won't get into trouble, we promise.
Okay, so you know what to do now? Seduce her. Get pics and texts with her. See those documents. Buddy, you don't know what a gold mine you're getting for us. This is going to be awesome! Um, er, we mean, very helpful in finding Kyron!
Just remember, the more you get on her, the more we'll have and the faster we'll put her away. We know you can do it! And no, no one will suspect this is a sting at all. No one will see it coming, especially Terri.
As much I see hints of it, I really don't think this was a sting. Sexts - pics and text - coming on to a crazy maybe murderer, and clearly breaking the law? LE wants facts, not tabloid fodder. And I don't even think Kaine would go this far, I really don't.
