Dr. Clark Murray
- Dr. Clark Murray: Note the rectangular bruising around these wounds here and here...
- Kate Beckett: Mm-hmm.
- Dr. Clark Murray: ...caused by the hilt of of the knife striking with force enough to compress the skin.
- Kate Beckett: And as a result, the injuries penetrate deeper than the actual length of the blade.
- Dr. Clark Murray: He's also honed the blade so fine it's brittle enough for bits to break when it strikes bone, which is why slivers of blade were found inside both of his victims... We now know those slivers come... from the same murder weapon.
- Kate Beckett: Wait. Two victims? How many people has he killed?
- Lanie Parish: Five... that we know of.
- Kate Beckett: So we're looking at a serial.
- Dr. Clark Murray: Well, yes and no. We believe we're dealing with a professional. Someone with extensive military training.
- Kate Beckett: A contract killer.
- Dr. Clark Murray: I used tomographic reconstruction of Coonan's wounds to generate a 3-D model of the blade used. It's a Special Operations Group knife, the kind favored by Special Forces in Gulf War I. He kills with a single blow, using these other wounds to camouflage the skill with which the initial stroke was delivered... The very same method and the very same weapon that the killer employed... ten years ago.
- Kate Beckett: [after long pause] Lanie...
- Lanie Parish: I'm so sorry.
- Dr. Clark Murray: Detective Beckett... there is no doubt in my mind... that Jack Coonan was killed by the same man who murdered your mother.
