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.

Yasir says, I didn't make that call.

I don't know anything.

Their notes from that conversation say, quote, If Adnan wanted to get rid of the car, where would he do so?

Ali indicated somewhere in the woods, possibly in Centennial Lake or the Inner Harbor, unquote.

No one has ever gotten to the bottom of who made this anonymous call.

The cops didn't figure it out.

Anand's attorney didn't figure it out.

I've tried to figure it out, too.

For a while, I couldn't let it go.

Because it seemed to me that whoever made this call, he must be the key to the whole thing.

But so far, I only have guesses that I can't responsibly say out loud.

Anyway, the day after the Pizza Hut talk on February 16th, the detectives do some paperwork that will ultimately crack the whole case open for them.

They get a subpoena for Adnan's cell phone records.
