(Cut to: ANGELA in the investigation room with HAROLD.) ANGELA: Okay, the lasers can measure the angle of the attack and the amount of damage that was done to the living bone of the skull; 3.3 millimeters indentation into the bone at the deepest point which trailed off to 0.04 millimeters. And from the victim's right. BOOTH: She was found in a ventilation shaft beneath the city. BRENNAN: Any man getting involved with a woman like Marni should know that she's adventurous and independent. But... Explain them to the rest of the world? GARFILED: Her latest project the last couple of months is about the maze of tunnels beneath the city. He lives in a cardboard box underground. I don't know how to talk to people who live underground and who might have tossed a documentary filmmaker down a hole. KYLE: Murder?! There are alternatives. Very valuable. What clue? What murder? Why? Your victim was in some other tunnel system before she died.
