NCIS Squad Room.

"I'm telling you probie you've got it all wrong."
"But it's the scenario that makes the most sense." McGee glares at DiNozzo as he continues. "Petty Officer Darren Brown" He brings the photo of Brown up on the plasma. "stole the items from the supply depot where he worked and passed them on to his brother." He brings the photo of Brown's brother up on the screen. "John Brown who in addition to running a pawn shop had a nice sideline in stolen property. When the Petty Officer found out the supply depot was going to be audited he wanted to lay low for awhile but his greedy brother wanted to keep going. They argue. John kills his brother and then disappears." He brings up the photo of Brown's body at the crime scene.
"No." DiNozzo shakes his head.
"Well what do you think happened Senior Field Agent DiNozzo?"
"I think it was the woman."
"What a surprise" mutters Ziva.
"What was the Officer David?"
"Nothing" she responds trying and utterly failing to look innocent. "Tell us more Tony."
"I think Darren's girlfriend" He brings her picture up. "Janice Smith found out about his activities and that he was putting their whole future together at risk. To make matters worse she had recently found out she is pregnant. She goes to confront him. They argue. She shoves him. He falls back, hits his head and dies. Remember Ducky said many of the injuries were caused postmortem? Well it is my contention they were caused by a furious woman continuing to hit and kick the man who has caused her so much pain." He grins at his colleagues as if expecting a round of applause.
"My scenario is more likely Tony. We don't even know if she knew what her boyfriend was up to."
"Ah but you forget the most important thing McLogic."
"What's that?"
"The rage."
"The rage?"
"Yes. If John had killed his brother it would've been a practical matter. The removal of a threat. This..." He waves a hand at the pictures on the plasma. "clearly shows anger towards the victim. It has to be the girlfriend. Your guy is just a small time fence. He's..."
"Straight and white" Ziva chimes in.
"Huh?"
"Like a picket fence, yes?" She grins at them.
"Huh?"
"You said he was a small time fence."
"A fence Ziva is simply another name for a receiver of stolen goods who then passes them on to a third party."
"Oh."
"So as I was saying I don't think John would display that level of violence. It was the girlfriend."
"And I still think it was the brother because he's disappeared."
"And I think both your theories have merit. That is..." chimes in Ziva.
"Well why don't you get off the fence and find me some evidence that proves your case." Gibbs contributes from behind Tony.
"On it Boss. Going to interview the girlfriend right now." Tony hurriedly gathers his gear as the Boss adds "Take Ziva." She gathers her gear and she and Tony head for the elevator. As the doors close behind them she asks "What fence was Gibbs talking about?"
