Corey figured that Carmen might have access to someone who could provide her with drugs.

And Carmen did.

A few days before Eric ate that Valentine's Day sandwich, Corey directed Carmen to a house she had flipped.

Carmen told investigators she went inside, took the cash Corey had left, and went to buy the drugs.

Carmen said she later returned and placed them in the backyard fire pit for Corey.

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.
