Sheldon Hawkes: Torres was a big time gangster, but I guess it's true what they say: you live by the gun...
Sid Hammerback: You get gunshot wounds.

Sheldon Hawkes: Two shootings. Same signature.
Don Flack: One gang, El Pu�o.
Jo Danville: So Torres' murder wasn't a rival hit by the Mambas; it was an inside job.
Sheldon Hawkes: So, just like a snakehead, someone in El Pu�o's eating their own.
Mac Taylor: I want to talk to each one of their power players. Lisa Brigosa, the Devarro brothers, Rick and Luther and Fernando Flores. Each one of them is either a potential suspect, or a potential victim.

Sheldon Hawkes: What about the trace I collected from her arm?
Lindsay Monroe: Latex. More specifically, condom spray.
Danny Messer: (Amused) 'Scuse me? What? I didn't catch that.
Lindsay Monroe: Liquid rubber (Holds the spray can, smiling) German engineering at its finest.
Sheldon Hawkes: I'm not sure I understand.
Lindsay Monroe: Well, allow me to demonstrate (Grabs a big test-tube) Contrary to what you might have heard, science definitely does matter (Starts spraying the content of the can on the test-tube) Simply, apply like so. Allow a few moments for maximum drying time and... Boom! Instant condom. (Hands test tube to Danny)
Sheldon Hawkes: Are you serious? A spray-on condom?
Danny Messer: What... Where does the... The... (Points at the top of the test-tube) Now how... Never mind.

Sheldon Hawkes: You got to be hurting a little bit today, huh, man?
Adam Ross: I got a, uh, you know, three-day suspension. It's pretty painful.
Danny Messer: Ah, come on. Hacking after Mac told you not to? You're lucky he didn't suspend you from the flagpole out front.
Sheldon Hawkes: Yeah, you go home, lick your wounds, uh, catch up on your soaps. You'll be fine.

Sheldon: (on discovering a picture locket) Found a piece of jewellery in pretty good shape.
Sid: Based on age, I'd say they're probably the victim's parents.
Sheldon: The job never gets easier does it?
Sid: I can tell you I've been working here twenty-nine years. That's 4846 cases and names I will never forget. What gets me through are people like them. Folks who are going to be looking to me for answers.

Sheldon: You know what my favorite games was when I was a kid?
Mac: Jacks?
Sheldon: Operation.
[He holds up a pair of tweezers and then uses them to remove a bullet from the body of a gunshot victim]
Mac: His nose didn't buzz red. Well done!

Sheriff Benson: (about the crime scene) This one's gonna be covered differently.
Danny: Why is that?
Sheriff Benson: Thirty-one years ago the former owner, Bill Willens shot himself in this house. Two days later, his daughter disappeared. Bill's wife, Betty, claims her husband was hearing voices. He told people the house was possessed by evil spirits.
Lindsay: Just like The Amityville Horror.
Sheriff Benson: All I know is the folks inside this house were good people. For Gil Duncan to shoot his family, commit suicide... there's gotta be an explanation other than ghosts made him do it.

Sheriff Benson: All I'm saying is people come to town and get caught up in the folklore.
Lindsay Monroe: Do we look like we're here buying postcards?

Sid Hammerback [to Jo]: You came from D.C., right?
Jo Danville: Yeah.
Sid Hammerback: It's an interesting town. I've only been there once to testify before Congress.
Jo Danville: Oh, on behalf of the National Academy of Sciences?
Sid Hammerback: Oh, no, no. I was there to testify that they have no business restructuring the College Bowl system. I never got past the door. But the town is... is quite... lovely.
Jo Danville: Okay.

Sid Hammerback: (looking at the body of their vic, who was sawed in half) Do I even need to state the cause of death?

Sid Hammerback: I enhanced the tattoo on the radial border of the Vic's upper arm and discovered this, what appears to be a wee little leprechaun holding a... basketball?
Jo Danville: Looks like a homemade rendition of, what? The Boston Celtics' mascot?
Sid Hammerback: Oh. Well, not a very good one.

Sid Hammerback: Oftentimes, damage to the temporal lobe results in seizures and those seizures have a tendency to start in the hands.
Mac Taylor: So it's possible the movement of her finger up and down was involuntary. You think I made a mistake showing her the photograph?
Sid Hammerback: Well, like you said, she was responsive and obeying commands. I hate to play devil's advocate here, Mac, but a defense attorney would have a field day with that ID. Bottom line, we don't have a picture of what happened in her brain when she moved her finger. So there's just no way to know if her ID is reliable.
Mac Taylor: And now she's defending her son.

Sid Hammerback: The human skull is composed of one of the most durable substances found in nature. It takes approximately one ton to reduce the diameter of the skull by one centimeter. Unfortunately for Walter Travers, when you get whacked in the head multiple times with a blunt-force object, that doesn't mean a whole lot.

Sid Hammerback: This is one of the most well-preserved mummies I've seen in my many years as a pathologist. The environmental conditions of temperature and humidity and ventilation must have been just optimum. I can only compare it to the best sex you've ever had, reaching climax at precisely that��
Peyton Driscoll: All right, Sid, you can help.

Sid Hammerback: This poor boy was beaten, cut and shot. Does it seem at all extreme for a simple street mugging?
