OPERATOR: This is Elizabeth.
What's the location?
PAUL ECKER: We learned that one of our motor vehicle service
drivers was shot and killed while he was in the course
of his duties on I-30.
We were able to identify the victim as Mr. Tony Mosby.
He had been with the Post Office about 14 years, 58 years of age
at the time.
THOMAS NOYES: There was multiple gunshots to the front
of Tony Mosby's postal truck.
One of the rounds had gone through the windshield
and struck him in the face.
And that was the round that took his life.

PAUL ECKER: Her relative worked for the Postal Service.
And I think once they had learned Mr. Mosby had died,
it was weighing on her.
In interviewing and interrogating anyone,
you have to make them comfortable.
She was very nervous, very scared,
because she knew this murder has been on the news.
She knew information about it.
CHRISTOPHER WALTON: A lot of times, people,
they're a little bit hesitant to come forward when it comes
down to these investigations.
They always have a saying, "snitches get stitches."
So we want to make sure that they can talk to us
and come forward about everything.
At that point, we have now identified
a shooter, Don Farrell.
[police radio chatter]
We already had an idea of what our challenges was.
We know that he will deny he had any involvement.
But also, he didn't know what we knew already.
CHRISTOPHER WALTON: It's all about that approach.
So that way, they'll know me, not just
a guy with a gun and badge.
Walking into that room knowing that everything is at stake--
it's game time.
Hey, what's up, man.
How you doing.
CHRISTOPHER WALTON: So the biggest thing
when I walked into that room, I wanted
to make him feel comfortable.
So my goal was to build a relationship with him,
build my rapport with him.
CHRISTOPHER WALTON: He kept using
the term he was "faded," meaning that he
was under the influence.
He was trying to make me believe that he was so drunk where he
just don't remember anything.
I knew that that wasn't truthful.
CHRISTOPHER WALTON: At any moment,
he could ask for his attorney, so I wanted to make
sure to keep him talking to me.
CHRISTOPHER WALTON: We set the foundation
where he could talk, made him comfortable,
and that way he felt as if he could talk to me.
He finally sank over in his chair,
and you saw his shoulders drop and his head drop.
And it seemed like the full acceptance was finally there.
He realized the show was over.
There wasn't any more denial.
There wasn't more covering it up.
