Detectives paid a visit to the owner of the house.

You've already met her, Molly Crosswhite.

How did you feel when you started to learn these details that this house that you bought might have been used to secure really a murder weapon of sorts, drugs?

In the interview room, the detectives were turning up the heat on Carmen.

She told them that just days before Eric died, Corey reached out again looking for more drugs.

I mean, I don't even know how...

Dark enough, as in strong enough.

Carmen said Corey wanted the Michael Jackson stuff.

Detectives tracked down Carmen's drug dealer, a man named Robert Crozier.

It wasn't that hard to find him.

He was in jail.

With the dealer corroborating Carmen's story, detectives now believe they had what they'd been searching for, the crucial link between Corey Richens and the fentanyl that killed her husband.

It was a Monday morning, a month after that TV appearance.

Law enforcement waited until Corey's boys were at school, and then they arrested her.

Corey Richens is here in the Summit County Jail tonight.

We're told she is being held without bail.

She wouldn't do that.

Yeah, it's a lot to process, especially in a small valley like this.

It's pretty heavy stuff.

Suddenly, the story of the grieving mother turned alleged killer who wrote a book to help her sons was everywhere.
