Hi guys, Nancy Grace here. Welcome back to Killers Among Us, a production of I Heart Media

and Crime Online.

Sarah Stern, her car, found abandoned late at night on a remote bridge in New Jersey.

What you'll hear in this episode is shocking.

Undercover video comes to light.

With us again, Sarah's dad, Michael Stern, who has fought so much pain to get through

this investigation.

Also with me, local reporter on the story from the get-go-Alex and pully-ello.

With me also, Lee Detective on the case Brian Weissbrot, Mama County prosecutor, Christopher

Grimicioni.

Also with us, renowned LA Psychoanalyst Dr. Bethany Marshall.

Right now police working under the theory Sarah did not commit suicide or just run off.

That will quickly become apparent as police get a call from a local teen who offers up

a suspect on a silver platter.

But is it real?

Let's pick up the story right now.

Let's extend a new relationship.

I'm sorry, pretty close friends.

Will she ever be your girlfriend now?

Sarah's friends and family portray her as this happy, go-lucky girl that never had any

reason to say she would hurt herself or hurt someone else.

But Liam Portray is a different picture.
