Five years, case closed, everyone thinks he's dead, and there he is.

Wouldn't be, if it wasn't for Walter.

Your son did a brave thing, Mrs. Collins.

You should be very proud of him.

l am.

You still think he's out there?

Why not?

Three boys made a run for it that night, Detective.

And if one got out,

then maybe either or both of the others did, too.

Maybe Walter's out there, having the same fears that he did.

Afraid to come home and identify himself,

or afraid he'll get into trouble.

But either way,

it gives me something l didn't have before tonight.

What's that?

Hope.
