The X-Files, Season 1

Det. Lazard:
I was right outside. I'm telling you, there was nobody else there except for Barbala and the kid.

Mulder:
So you didn't get a description of who the kid saw?

Det. Lazard:
I'm telling you, there was no one else. Listen. The department is treating this as a suicide, but I gotta tell you. I knew this guy. There's no way he did himself.

Scully:
Was he depressed or under psychiatric care of any kind?

Det. Lazard:
No. Only time he ever looked at himself was in the mirror. And he always liked what he saw.

Mulder:
Plus jumpers tend to open the window before they jump.
