So what was Aaron's response to the social media campaign that's growing around him?

Okay, Marianne, that's the backdrop, if you can believe it, of the alleged murder-for-hire scheme.

So according to investigators, Angie was looking for someone to kill her husband.

This was in April.

She met up with undercover officers from the Tennessee Bureau of Investigation.

How did all that play out?

What happened?

So what are investigators saying about a possible motive for this alleged arrangement, murder for hire arrangement?

I'm curious, you know, I can't imagine receiving this kind of news, but how did Aaron react to news of his ex-wife's arrest?

We should reiterate that Angie has pleaded not guilty.

Her attorney said at the probable cause hearing that there were a lot of things said in the car that she didn't mean.

So we'll see what else they have to say at the hearing coming up next week.

What do we know about that?

Well, Marianne, thanks for keeping us up to date on this one.

It is a fascinating one with a lot of twists and turns.

We'll check in with you as it progresses.

Thanks very much.
