At around 6 a.m., detectives believe Jay, chatting on the phone with Khalid, was driving to meet Red Eye.

That's when detectives believe Jay showed up at Red Eye's front door.

We were confident that that was the last person that saw Jay Lee alive.

And I make a phone call to a friend at the U.S.

Attorney's office and just say, how can you help us?

The U.S.

Attorney filed a federal warrant and this time Snapchat delivered.

So that really was a turning point.

Now the detectives had Red Eye's email address and found it was the same email for a podcast called Dirt to Diamonds.

The host, a handsome 22-year-old man and fellow Ole Miss graduate.

Tim Harrington.

What do you learn about Tim Harrington?

Highly thought of on the Ole Miss campus.

I was a good student.

Jay's friend Braylon knew him well.

I definitely had leaned on Tim Harrington for help in the past.

He was giving me advice on, you know, how to stay out of trouble and what to do if your grades are bad.

I looked at Tim as a friend.

You have those people who kind of like take you under their wing.

Was Tim kind of like that?
