Four students just starting out, not knowing that soon their lives would violently collide with a Ph.D.

student in criminology at another university just across the state line.

So on November 12th is when that iconic photo is taken, the last known photo of the four victims all together with their roommates, Bethany and Dylan, all six of them before their big night on game day.

They've had so many Saturday nights just like this.

There was nothing out of the ordinary about this Saturday night in Moscow, or so they thought.

Hours later, friends make a horrific discovery.

We saw it on our phones before they told us directly.

It was like, what, quadruple homicide?

The most important thing to me was, who did this?

Why did they do it?

This is Moscow.

It doesn't take very long before state police, then the FBI, all join the search for this killer.

We realized that there was a security camera right next door to our residence.

Once we had that, we quickly realized that we had this white vehicle.

And so that was the introduction of the white Elantra for us.

We don't know when this person is going to strike again, if they're going to strike again.

And the pressure on us to solve alone, our own internal pressure was huge.

And at the same time, you've got the public pressure to find the perpetrator.

There's a crush of media.

It overwhelms the tiny town of Moscow, along with the lives of everyone touched by these shocking murders.
