  • This episode was interesting with a very complicated case, and great acting was displayed as always. It centers around Keppler and his past, which ties him to the present. The other news is that Grissom came back from his sabbatical.

  • Quotes (17)

    • Archie (about Keppler): He just disabled his GPS. Smart guy. Greg: Guilty guy.

    • Catherine: He's being set up. Grissom: Why? By whom? Keppler told me he didn't know Frank McCarty. Warrick: He also said that he didn't know the victim, maybe he's lyin' about that too. (Catherine gives him a look) I'm sorry, Catherine, I like the guy too but I'm just following the evidence. Nick: We should be talkin' to Keppler about this. Grissom: Where is he? Catherine: He was with me in AV, nobody has seen him since and he's not answering his cell. Nick: He knows where the eyewitness lives. Catherine: What're you sayin', Nick? Nick: I'm sayin' that if he was involved in these murders, Frank McCarty isn't the only one that we need worry about. Catherine: Well, PD's on their way to Suzy Gibbons apartment now. Grissom: Okay, grab Sara and go over there now. I'll call Brass and tell him to talk to Trenton PD and see who knows who. Catherine: Welcome home. (leaves) Grissom: Okay, what other evidence did Keppler handle? Nick: He brought back the three bullets from autopsy. Which didn't match the gun with his prints on it. Grissom: Could he have swapped the bullets? Nick: Anything's possible. Warrick: He also searched the dumpster where the homeless guy found the hooker's purse and cell phone. He told Catherine he didn't find anything. Wendy (walks in): I got your DNA results and the blood on the gun from Frank McCarty's hotel room, it doesn't match either victim, no hits in CODIS and the DNA print and screen markers say that it is from a black male. Nick: Keppler and McCarty were both Jersey boys, expand the search to the east coast. Wendy: Will do. I really hope he's clean. (leaves) Grissom: We have to treat him as a suspect. I'll tell Ecklie.

    • Keppler: She had a kid. Frank: Oh, god. Keppler: Why don't you tell me about the hand? Frank: She scratched me, Mike. Come on, what was I supposed to do? I couldn't take the chance that one of your guys would find my DNA under her nails. Keppler: Why, Frank? Frank: You know why. Keppler: That was a long time ago. Dennis never said a word. Frank: Yeah, but he was going to. He was about to be indicted. Wife, three kids, there was no way that he was doin' time. He was goin' down, Mikey, and he was takin' us with him. Keppler: He was a cop, Frank. You taught me that, you don't do that. Not even to save your own ass. Frank: Yeah, what about yours?

    • Grissom: I hear that there was some friction in the lab when I was gone. Warrick: Did you ever hear of reverse forensics? (Grissom looks up at him, a little shocked)

    • Grissom: Michael Keppler. Gil Grissom. (they shake hands) How's everybody been treatin' 'ya? Keppler: No complaints. You got a great team. Grissom: Yeah, thanks. Does Ecklie still have you slotted for days? Keppler: As far as I know. Grissom: I hear you're working the double homicide at the Olympia. Whaddaya got? Kepplr: Oh, bullets from Doc Robbins. I was gonna run 'em through IBIS. Grissom: Dead cop was from your home town, huh? Keppler: Yeah. Retired. Grissom: Did you know 'em? Keppler (scoffs): You know how many retired cops there are in Trenton? (pause) Well, it was great to finally meet you.
