They talk to almost everybody I know.

If they haven't already, they won't.

The exchange alarmed Anthony enough that he decided to get a record of it.

On Snapchat, when you open a message, it disappears when you close it.

And if you screenshot the conversation, the other person would know.

So Anthony said he took a picture of Liam's message with his digital camera.

Authorities said Anthony told them the constant messages from Liam didn't stop.

The two usually talked or texted, but Liam kept reaching out over Snapchat.

He wanted to get together with Anthony in person.

And he was persistent.

Anthony said he just kept telling Liam that he was busy or working.

But the truth is, investigators said Anthony was terrified.

He couldn't sleep or eat.

He kept thinking, if Liam really did hurt Sarah, who's to say Liam wouldn't come after him?

There hadn't been any new movement on Sarah's case in weeks, and police were desperate for any new leads.

But when Anthony came forward with this story well over a month after she went missing, investigators admitted that it sounded too crazy to be true.

That's Chris Decker.

He's an assistant prosecutor for Monmouth County who got assigned to Sarah's case.

As wild as Anthony's story sounded, could it be true?

Investigators noted how specific and detailed Anthony's story was, like how he said Liam told him Sarah found the money in an orange envelope and had a safe at a bank in Bradley Beach.
