Who Bought the Poison?? #maryyoder #truecrimestories #truecrimeshorts | Forensic Files

So she admits to buying the cards, but she is still insistent she didn't actually buy the colchicine. And the
only explanation she can offer is that somehow Adam must have used them. Even though according to investigators cell
records show that Adam was nowhere near Katie on the day that she scanned the documents needed to make the purchase.
Those documents were scanned in your phone. I know that. And you were in possession of your phone.
Where are you at crossroad right now, Katie? And I'm going to be honest with you.
You lied to me earlier when you said you don't know how those were scanned. I know for a fact [music] that you were in
possession of your phone when they were scanned. Yes. You're saying you purchased this credit
card and it was immediately used for the payment within a day. Who did you give that credit card to then?
If that's the road we're going to go down, let's keep rolling this snowball. That's not the only hole in her story.
You see, investigators had found a draft of the anonymous letter saved on the Google Drive connected to that Gmail
account. It had been edited in November, right before it was sent. So now, if Katie admits to writing that
letter, she is also admitting that she had access to the Gmail account. And if she was the one using the account, she
is the one who ordered the poison.

In Part 2 of the Mary Yoder case, investigators confront Kaitlyn Conley about prepaid credit cards and the purchase of colchicine.

Cell records, scanned documents, and a draft of the anonymous letter tied to a Gmail account begin to raise serious questions. If she had access to the account, investigators believe she may have ordered the colchicine.
