I'm Sarah Koenig.

Remember how last time I ended by saying that the detectives had other leads in this case besides Mr. S., the guy who found Hay's body?

That they were also starting to look at Adnan?

Well, the reason we know that is because of this memo.

This memo he's talking about is regarding an anonymous call.

That's Detective Ritz on the witness stand at trial.

He's talking about how they got this anonymous call three days after Hay's body was found.

The call came in to Detective Massey, a Baltimore County cop.

The caller must have had an accent of some kind because Massey's report describes him as an Asian male, 18 to 21 years old.

though it's unclear whether Asian in this case means East Asian like Korean or South Asian like Pakistani.

But anyway, a mystery caller says, look at the ex-boyfriend.

The caller hangs up.

Then, a few minutes later, the same guy calls back and says, oh yeah, by the way.

This time, the caller mentions a friend of Adnan's, Basr Ali.

Actually, the name of this friend is Yasir Ali.

The caller says, Yasir might know something.

Hangs up again.

The cops can't trace the call.

It's out of range.

Three days after the anonymous call, the detectives go meet with Yasir Ali at a pizza hut.
