Tammy Felton, played by Brigid Brannagh, was also featured in the episode "Face Life".

(Warrick sticks out his finger)
Nick: I'm not pulling it.

Grissom: Dressed as a woman among men dressed as women. Now, see? That's a disguise.

Catherine: The town just lost 5% of the population.
Sara: I thought you said that this was a single homcide.
Catherine: Yeah in a population of 20 people.

Gil: And the body count?
Jim: Five guards, three civilians wounded. One dead bad guy. Armed robbers snatched the lock boxes from the two high-stakes tables right off the rolling cage.
Gil: Cash on wheels.
Jim: Busiest time of night. Three women-organized and muscled.
Gil: Small time crooks, Jim.
Jim: Hey, they got away with 250K.
Gil: Yeah? That's a mere pittance to a Vegas casino. Cashiers alone are sitting on a million and change.
(They reach the red-haired woman.)
Jim: Small time or not these ladies are dangerous.
(Grissom glances down a the body. He puts his kit down and kneels down next to the body. The looks up at Brass)
Gil: Dangerous, yes. Ladies ...
(Grissom reaches over and pulls the red-haired wig off of the "woman". He holds it up to Brass and shakes his head.)
Gil: ... no.

Jim: The same M.O. as Laughlin. Last month, cottage casino, men dressed as women shot the place to hell. In and out in under five.
Gil: My bet was that that was the practice run.
Jim: And the more you practice ...
(Brass and Grissom walk up to Max Duncan talking with an Officer. They overhear part of what he says.)
Max Duncan: I don't know what the hell's going on with the world. Everything's crazy. I risk my life just coming into work. Makes you miss the mob days, huh?
Back then, this never would've happened. And if it did, those scumbags, they'd be dead, every last one of them and we would never know about it.
Jim: Mr ... Mr. Duncan -- take a deep breath and tell us what happened.
Max Duncan: We'd just made a money transfer to the rolling cages. Then, bang-- the chandelier comes crashing down. Sounded like an explosion. So I dropped to my knees-- I took cover.
Jim: Anything else?
Max Duncan: Yeah, I started praying for the gunfire to stop.

Gil: The falling chandelier distracts the guards. Makes them easy targets. The armed robbers load up, head for the exits.
Jim: Quick escape.
Gil: Chaos moving in one direction, the money moving in the other.

Sara: Vomit?
(Catherine picks up a sample and smells it. She shakes her head.)
Catherine: Not an expectorate. Potato. Blown to smithereens.
Sara: A poor man's silencer.
Catherine: Now, why would an assailant need silencer way out here?

Elderly Woman: I said four.
Jim: Right.
Elderly Woman: There were four of those lunatics. They were everywhere.
Jim: Right.
Elderly Woman: (insistent) Write it down.
Jim: I got it. Thank you very much. Excuse me.
(Brass walks away from the Elderly Woman. Grissom walks up to Brass)
Jim: (clears throat) I've interviewed 17 people. No two accounts are alike.
(He puts his notebook away.)
Gil: A Harvard Professor conducted an experiment. Asked a bunch of students to watch a basketball game -- count the number of times the ball was passed.
Jim: Yeah, groundbreaking.
Gil: During the game a person dressed in a gorilla suit ran across the court. Afterwards, the professor asked his students if they noticed the gorilla. Fifty percent responded, "What gorilla?"
Jim: That's wonderful, Gil. If I see a gorilla, I'll arrest it.

Gil: This is the video surveillance from that heist. This camera was trained on their entrance.
(On the monitor, the three "ladies" walk into the casino. The blond stays by the stairs, the Red and Blue walk into the casino.)
Gil: All the disguises in the world and they dress like women.
Warrick: Ski masks are played out. Red and blue teamed up together and took out the guards and their rolling cage.
(On the monitor, the Red and the Blue walk across the floor and shoot the guards. The players duck down for cover.)
Warrick: Black shot down that chandelier.
Gil: Well, Blue's the decedent I.D.'d as Adam Brower ... so enlarge red.
(On the monitor, the frame is on pause and the picture of the woman in Red is enlarged.)
Warrick: No amount of makeup in the world could cover up that chunk of adam's apple.
Gil: That must be the one that killed Brower. .45 in the back at close range.
Warrick: No honor among thieves.
Gil: Photoshop black.
(Warrick highlights and enlarges a close up of the blonde-haired woman in Black.)
Warrick: No stubble ... no adam's apple.
Gil: Dressed as a woman among men dressed as women. Now, see? That's a disguise.

Greg: So, ballistics sent me a bullet from the casino. It's a .45 so we know
it came from one of the "ladies'" guns.
Gil: And this is a special bullet?
Greg: No, but there was a foreign substance adhered to it.
Gil: And the substance is special?
Greg: Not exactly.
Catherine: Just get to the point, Greg.
Greg: Tomato, to-mah-to, potato...
Catherine: Wait a second. There was potato on the bullet?
(Grissom turns to look at Catherine. He knows she knows something.)
Greg: You bet. Strange, huh?
Catherine: There was potato on the bullet because there was potato inside the barrel of the gun.
Gil: This bullet is from my investigation.
Catherine: Right. One of your armed robbers may have used a potato as a silencer prior to the heist.
Gil: Tammy Felton?
Catherine: (shakes her head) Maybe.
Gil: Three armed robbers. Adam Brower-- killed at the scene Tammy Felton ... we're still one suspect short.
(Sara enters the lab. She pulls out the photo sheet from the envelope. She gives it to Catherine.)
Sara: Cath, got another match from the convenience store. The print on the outside doorknob belongs to an ex-con, Darin Hanson.
(Grissom looks at Catherine. They both look at each other. Sara recognizes the look.)
Sara: You know this guy, too?
Catherine: He ran with Tammy's father, mostly from the law.
Gil: So Tammy kills dad ... and she and Darin Hanson run off together.
Catherine: A regular Bonnie and Clyde. Just what Vegas needs.
