Detective John Diebel

There was a lot of moving of money around of the doctors, not to Carter, to Rebecca's two sons.

Kind of under the radar, without the doctor's knowledge.

She funded a Verizon cell phone shop in Portage, Wisconsin, for her first son, a brewery for Ben, and some other businesses that had failed.

This is terrible, but she'd always refer to Carter as the bastard.

And she'd come in and say... The bastard.

The bastard.

One of her kind of go-to lines was always, I could just kill him.

I could just kill him.

And just the look on her face and just how frustrated and she just like would...

physically, you know, kind of altered and just so angry.

What was she mad about?

It could be anything from, you know, having handed out money to patients to, you know, having written a small check to Carter.

I said, Becky, what's...

What's going on?

And she says, well, they can't confirm it's him.

They won't let me in the house.

But we know it's him.

Just confirmed my suspicions all the more.

She's involved in this murder.

She murdered him.
