CSI: Miami

Jay Fisher, a known jeweler and suspected drug-dealer, is found dead in his home at Coconut Grove with three gunshot wounds on his body. Horatio and Tripp are having a look around the scene when suddenly the skylight shatters and a man comes crashing down on the victim. The man, Johnny Nixon, is arrested and tells them he was hiding from the shooter on the roof. He has blood on him; Tripp wonders if it's from falling on the victim or shooting the victim. Horatio tells the officers to take him away but Johnny asks Horatio if he wants to know what he's got on one of his CSIs. This gets Horatio's attention. Johnny grins and tells him that he is a drug dealer for Eric Delko. He even has is private phone number. Horatio takes a look at the phone and recognises the number. He calls it and gets Delko's voice mail.

Johnny is brought in for questioning. He admits to being there to buy drugs but he didn't shoot anybody. He was upstairs when he heard Jay argue with somebody, and then gunfire. Johnny doesn't know who Jay was arguing with.

Delko comes in to work and spots Johnny in the interrogation room. He clearly recognises him. Horatio wants to talk to Delko. He tells him what Johnny has claimed and Delko has no choice but to admit that it's true. He needs Horatio to know that there were extenuating circumstances. Horatio stresses that he can't talk to anybody, especially not Internal Affairs, no matter what the circumstances were. As if on cue Rick Stetler arrives. Before Delko can say anything about what happened Horatio tells Stetler that Delko wants to talk to his union rep before he talks to Stetler. Stetler still needs a urine test from Delko and a chat with the other members of the team, including Horatio. Horatio is already working on getting Delko out of the situation and points out to Stetler that the witness is actually a suspect in a murder investigation. Rick leaves to talk to Johnny and Delko assures Horatio that he's not smoking pot. Horatio doesn't answer.

Back at the crime scene Alexx is examening Jay while Calleigh processes the scene. Calleigh notes that while Jay has three wounds there are four casings, all 9mm. Perhaps the fourth bullet went through the skylight? Unfortunately the location of the casings won't be of any help, since Johnny scattered them when he fell. Alexx tells Calleigh what Johnny said about Delko. Calleigh doesn't seem too surprised, but she doesn't want to believe that Delko is on drugs.

Outside Wolfe is working when Boa Vista appears. She lives up the street and heard all the commotion. Wolfe lets her in, surprised to hear that she lives in this fancy neighbourhood, but she doesn't seem to keen on talking about it. She asks if she can observe while he works the scene. He agrees and tells her he's just about to check the intercom. Someone hit it, and it might be the killer. Making small talk he asks if this is her first time on a crime scene. She replies that it's her first by choice, but her second in total. Boa Vista walks over to the intercom and steps on something on the way. It's a small piece of glass, hopefully from the window of the car that hit the intercom. She's embarassed that she stepped on evidence but Wolfe lets her off the hook, although suggests that she should look with her eyes rather than her feet next time.

At the lab Aaron takes a look at the glass. It's got Department of Transportation numbers, which will tell them the make, model and VIN number. They run it through the database and find a match.

Tripp tracks down the car, a red Solstice Coupe, and apprehends Deana Walters. She is not too happy being handcuffed by the police but Tripp is immune to her hootchie-mama mannerisms. He wonders why she has cuts on her lip and scratches. She admits that she was at Jay's house and he got angry when she couldn't pay a debt. He tried to take the gold and diamond grill out of her mouth so she kicked him in the crotch and ran out, smashing into the intercom with her car as she drove off. Tripp finds a 9mm under her seat and brings her in.

Back at the lab Wolfe and Calleigh run into Stetler. Calleigh knows that something is not right but she is firmly set on not letting it on. Wolfe is not as good as hiding his concerns. While Delko leaves his urine sample Stetler interviews Calleigh. She answers a firm "no" to all of Stetler's questions. It's then Wolfe's turn to be interviewed. He's clearly not fond of Stetler and the investigation and like Calleigh he firmly states that he's never seen Delko smoke marijuana or buy it. But when Stetler asks if he's seen Delko with any drug paraphernalia Wolfe is cornered. He has seen something and he is under oath, but he doesn't want to sell out Delko. He answers that he's never seen him with anything illegal, just with rolling papers. Knowing it looks bad he adds that he thought they were for cigarettes. Stetler doesn't buy it. They both know Delko doesn't smoke cigarettes.

Calleigh goes down to Firearms, hoping to have results from Deana's gun. Jim Markham has not tested it yet however. Calleigh is not happy with his sloppy style and his attitude. He doesn't think the case is important; one drug dealer shooting another is a victimless crime in his eyes. Fed-up with him she has him transferred and takes her old lab back. She then tests the gun, unable to keep a smile off her face.

Deana's gun doesn't match the bullets that shot Jay. There was also no gunshot residue on Johnny's hands. Neither of them killed Jay. Wolfe hands her the crime scene photos so that she can do a reconstruction. The photos are out of focus. Wolfe thinks there's something wrong with his camera, but Calleigh is worried that his eye is the problem. Wolfe brushes her off, but goes down to see Alexx. She examins his eye and finds an infection. Wolfe says it's not a big deal but Alexx won't have it. An infection in the eye you had a nail sticking out of two weeks ago is a very big deal. She wants him to see an ophthalmologist. Wolfe admits he's concerned. If there is a problem with his eye he will lose his job. Alexx tells him he needs to worry about losing his eyesight, rather than his job. She prescribes antibiotics and he needs to take them for the full two weeks. He agrees and promises he'll see an ophthalmologist.

Tripp helps Calleigh out at the crime scene, trying to determine where the shooter was standing. One bullet went through the victim and Calleigh finds it. It's a .45 caliber. That means two guns, two shooters. With the help of a laser beam they find that the shooter could have been standing outside, firing through a window. Calleigh checks the window and finds prints, both footprints on the ground and fingerprints on the opened window. The prints belong to Duane "Bull" Merrick from Los Angeles. Calleigh checks his credit card bills to see where in Miami he's staying.

Horatio brings a team to apprehend Bull. Tripp notices that he has cameras, maps and guns in his room. One of the guns is a .45. Horatio guesses that Bull is a bounty hunter and Bull confirms his guess. Bull won't tell them what the price was for Jay and gets angry when Horatio tries to take a closer look at his photographs. He is brough in for questioning.

Calleigh checks Bull's pictures on the computer. Wolfe comes in and asks what she's up to. Calleigh tells him she's hoping to find a lead in the pictures. Bull's gun was used to shoot Jay, but it didn't kill him, so the killer is still at large. As they look through the pictures they suddenly find some that were taken moments before Jay was killed. Wolfe spots a man reflected in the mirror behind Jay. Whoever that man is, he shot Jay Fisher.

Tripp and Horatio talk to Bull. Since Jay had no warrants Bull had no business being at his house. Horatio thinks he was actually after the second shooter. Bull won't tell them the man's name. They are both out to catch this man, and Bull is not going to help them beat him at his job. The only thing he's willing to tell them is that the suspect was dealing drugs in Jay's territory, stepping on his toes. He watched the two have an argument and Jay pulled his gun at the other man. Bull shot Jay to prevent him from shooting Bull's human paycheck. The other man then picked up the weapon and shot Jay twice, killing him. Bull is going to get out on bail and then he will catch him. Horatio intends to beat him to it.

Delko is working, watched from a distance by Horatio, when Stetler arrives. Delko tested positive for THC, the key ingredient in marijuana. Delko has nothing to say and is relieved of duty. Stetler will not pass out the opportunity to make a big show out of escorting one of Horatio's officers out of the building. Delko has no choice but to follow them, humiliated by having all his co-workers watch his escort. Calleigh and Wolfe watch in astonishment. Horatio does not plan on watching. He steps in and interrupts them, positive that there must be an explination for Delko's test results. Stetler wonders if Horatio has an explination for why one of Delko's co-workers ratted him out. Horatio says he can't, while Delko glares at Calleigh and Wolfe, having a good guess which one of them said too much. All evidence against Delko are circumstantial however; Horatio doesn't see the need in escorting him to IAB when he knows the way. He doesn't care about protocol; his officer is not a criminal. Stetler hasn't claimed that he is, but he is not allowed to drive a county vehicle until they have determined for sure. Delko is clearly bothered by being talked about in third person when he's standing right there. Horatio will not have Stetler carry on with his big show and tells him that he is going to give Delko a ride. Delko is thankful and heads downstairs while Horatio finishes talking to Stetler. He doesn't believe that this is about Delko; it's about himself and Stetler. Stetler tells Horatio why he doesn't like him. They were both candidates for the promotion to Lieutenant, and even though Stetler did better than Horatio in both the written test and the interview he didn't get the job. He believes Horatio stole the promotion away from him by doing some favor for the chief. The only way Stetler can be promoted to Lieutenant now is by paying his dues at IAB, and everybody hates IAB. So when he gets assigned to investigate one of Horatio's officers he will make the most of it. Horatio is angry that Stetler punishes his lab for what he feels Horatio has done to him, but to Stetler it's just about evening the score. It's a dangerous game, but Stetler intends to win.

Wolfe takes the picture they have of the unknown shooter to Cooper, hoping to be able to match the facial profile. Cooper uses the profile shot to create a full face, but since faces aren't symmetrical the end result doesn't look like the suspect will. Cooper is going to make slight changes to the side of the face that wasn't shown in the photo and try to find a match. Calleigh comes in and she and Wolfe try to map out everything they know about their suspect. He's from California and he was standing in the crime scene.

They talk to Johnny, who was also at the crime scene, only he fell into it. They need his clothes. Johnny doesn't want to undress in front of Calleigh but Wolfe has no sympathy for him. He's the reason why Delko had to pee in a cup in front of officers from IAB, so Johnny had better strip. He doesn't get very far with undressing though before Calleigh notices gum stuck on his jacket. There's glass in it. It must have come from the crime scene, when Johnny rolled off of Jay. With any luck it will belong to their John Doe.

Valera confirms that the DNA on the gum did not come from Johnny, Jay or Bull. Wolfe tells her to start searching for a match in California. Boa Vista is working in the lab and looks up when she hears California. She saw a black truck parked near her house that morning which had California plates. Valera finds a match for the DNA. Byron Diller, wanted for vehicular manslaughter and DUI. The picture of Byron looks like the man in the picture, but Wolfe feels like something's wrong. Valera tells him that Byron has four aliases; maybe he has as many faces?

Wolfe tells Tripp what they found and adds that since Byron has changed his face before he is probably going to do it now too. Tripp knows a plastic surgeon who works for cash. Wolfe notes that he does seem a little tight around the eyes, but the joke is not appreciated. Tripp tells him he busted the guy, Dr Milford, for changing the appearences of felons.

Together with Horatio Tripp goes to talk to Milford. He admits that it might be a long shot, but then a shot is heard. It looks like they might have the right doctor after all. With their guns drawn they pass through the house to find Milford firing at Bull, who has handcuffed Byron and taken off in Milford's boat. Shortly thereafter Bull ditches the boat and brings the still bleeding Byron to Dade County Jail. Horatio has predicted this move and is there waiting. Bull just wants his booking receipt, then he'll be on his way. Byron protests and claims that Bull shot Jay. Horatio listens to Byron's claim that Jay hit him when they argued and while he was on the ground Bull came in through the window. Byron ran from the scene and heard two shots fired on his way out. It's Byron's word against Bull's.

Wolfe and Boa Vista return to the street where she lives to take another look. Hopefully the car she saw belonged to Bull, and hopefully he tossed the murder weapon before he drove off. They are in luck. Wolfe finds the weapon and brings it in to the lab.

Bull's finger prints are all over the gun. Now he's cornerd and changes his story. He did shoot Jay, but it was in self defence. Neither Tripp nor Horatio believe that. Nobody saw Bull there until he fired the first shot. They have him for murder. Though they still need to find out who tipped him off about the feud between Byron and Jay. Bull tells them that it was Johnny Nixon. He not only tipped him off, he gave him directions which makes him an accomplice. Horatio knows that it not only adds time to Johnny's sentence, it might be of further help on a different matter.

Horatio talks to Marisol, Delko's sister. He remembers Calleigh mentioning seeing Delko with a woman at the hospital and put the pieces together. Marisol tells Horatio that Delko doesn't do drugs; he just sits with her when she does. She has cancer and smokes to help with the nausea from chemotherapy. Delko sits with her when she gets her treatment and then helps her with the marijuana so that she can keep her food down. Delko also pays her bills since she can't work anymore, and he drives her wherever she needs to go. That's why he's been late so often. Marisol is feeling very guilty that he's been trying to help her and all he's getting for it is losing his job. Horatio tells her he is not going to let that happen and he is not going to let Marisol take the fall in order to save her brother. Horatio knows what it's like to risk everything to help a family member and he assures Marisol that losing his job means nothing to Delko so long as he doesn't lose his sister. Marisol smiles at him, sensing a mutual attraction between them.

Stetler wants Horatio to meet up with him and Monica West from the State Attorney's office. It's clear that they think they have the upper hand but Horatio doesn't agree. He wants to know on what grounds they tested Delko. Stetler replies with the grounds stated in protocol: "reasonable suspicion based on identification of said employee as a suspect in a criminal investigation involving illegal drug use by reliable and credible sources". The source in this case being Johnny Nixon. Horatio informs West that their source is actually a known drug dealer and an accomplice to murder. Knowing that the source isn't going to hold Stetler turns focus to the urine test. However the exposure could have been passive; there is no way of prooving that it came from active use. West is not impressed. It's word against word, and a drug dealer is not going to be believed over a cop. The dangerous game Stetler played is over. Horatio won.

Delko is released. He meets up with Horatio, both happy to see each other. Delko apologises for not having told Horatio what has been going on, but Horatio doesn't need an apology. Delko was looking out for his sister, and Horatio understands perfectly. He does however need to know that it won't happen again. Something like this could really damage their lab. Delko assures him that it won't happen again. Horatio tells him his sister is lucky to have him, but Delko thinks it's the other way around. He heads off and Horatio watches him go with a smile on his face.
