Arriving on the scene, Olivia talks the acting SWAT lieutenant into let Fin go in and talk to his partner. He walks in and quickly finds a roughly bandaged Chester, who's got the drop on him. Cecilia is also there, wearing Chester's bulletproof vest that he must have had stashed somewhere. It's not exactly a joyful reunion, and Chester quickly realizes that he's holding a pretty shitty hand here. Even Cecilia is legally an accomplice rather than a hostage for bringing Chester the bandages that are currently dripping on the dusty floor. After Fin convinces Chester that they've followed Chester's trail and proved Kralik was guilty, Chester explains that he got a call from a guy named Jensen offering information on the Hernandez case, and then when Chester showed up at the meet, the bullets started flying. Cecilia volunteers that she can identify the face of the man who raped her. Resolved already? But it's so early in the hour.
Meanwhile, Munch is telling Cragen all about Kralik's other buddy Crane, who's had any number of complaints lodged against him. But since everyone recanted, he's still on the force, specifically the Fugitive Apprehension Team, Even more specifically, as we see, he's on the rooftop across from Chester's hideout with a sniper rifle, waiting for a shot. "Son of a bitch," Cragen breathes, as though he can see this. Fortunately, Elliot can, and he and Olivia sneak up behind Crane and take him into custody before he can fire.
Cecilia testifies in court about the day two cops offered she and Alisa a ride home, and forcibly took rides of their own. She identifies Crane, sitting at the defense table, as one of the perps. After Casey finishes getting Cecilia's testimony, the defense attorney brings up Cecilia's immigration status, over Casey's objection. Yes, Cecilia isn't exactly here legally, which I guess means she didn't' get raped after all or something.
With the credibility of Casey's witness thus brought into question by fear of scary brown people without the right papers, Casey turns to Warner to ask if the partial DNA profile can prove Crane was a match. Warner thinks so, but can't support it scientifically if the defense rebuts. Casey is not happy about this, but leaning on Warner doesn't get her anywhere.
