CSI: NY

Someone is being chased in a park in the snow, he gets killed. Morning and Mac and Stella or on the scene. Four impressions, different. Mac and Stella are using sculpture and pouring it in the impressions while Stella spray paints the different foot impressions. On one impression Mac finds a large splinter of a baseball bat. She also found tire tracks. Hawkes informs them about the corpse. the tattoo was scraped or sanded off. Then with the flash there is blood spatter on his face.

Aiden and Danny are on scene of a car crash. There is silver paint transfer on her cherry red car. A hit and run, the vic is a female, Marta Santo. There were also some bruising and vaginal tearing- possibly rape. Danny contacts the husband who comes to see her. He talks to her dead body through the glass, asking her why she went to work. He broke through the glass to go to her and freaks out.

Mac is with the mom of the child who died, Paul. She is upset thinks it's her fault, but Mac assures her it's not. He thinks perhaps the son was in a gang and though the mother denies it she admits she didn't know what her son was up to.

Aiden is on a different crime scene, Flack is with her. A store owner's brother was shot behind the counter, the vic is Mihok Lev. Flack gets surveillance from there.

Mac is examining the splinter from the baseball bat under the scope- a Mickey Mantle. It's a bat that's easily 5 grand.

Danny is working on the flakes from the car. And Aiden comes in, discussing the findings. He finds an infrared fingerprint on tee car, and she goes off to run it with the lab.

Mac finds some substance on the shoe impression- some weird shavings, like shuffleboard wax which was found on his shirt. Jane beeps Mac, and she found the killer of Mihok, the clerk: it was Paul. Stella and Mac examine the surveillance footage from the robbery and it turns out to show the brother chasing the killer with a bat…he returns 1 hr and 6 minutes after the shooting, enough time to commit murder. He claims he didn't kill him and chased him. The bat he had was aluminum.

On the sleeve of Mrs. Santo, there are multiple donors of sperm. The husband has 6 counts of domestic violence in two years.

Hawkes is with Mac and attempts to restore the tattoo by applying a second degree burn and letting It rise. The tattoo says tangle wood. Mac says he doesn't know many who have spent much time there, but he knows who has: Danny. It's a fake, no in date, or out date. He is a wannabe. Danny claims it's not mobsters to worry about but the next generation. When asked what the diff is Danny says it's that these kids don't give up. He tells him that as to rival crews- it's the Pelham crew. If you're fronting being a Tanglewood Boy and get caught by a real one or a fake Tanglewood boy get caught by a Pelham boy it's just as deadly.

Danny and Aiden are with Mr. Santo. He apologizes for breaking through the glass, and they confront him with his priors. He explains that she was a nympho and liked it rough so he gave it to her rough. He rides a motorcycle. They confront him about the other donors on her sleeve, and he is shocked and says no she worked at a hair salon in the west village. When they go there it turns out to be a massage parlor. The boss, Madam Tuki.

They go to her work station and Aiden finds something that looks like either a gem or an earring on the floor. Danny finds a towel with a lot of semen on it; Aiden looks at the massage client list. Her last client was an R.Lee.

Danny enters Mac's office who is adjusting his gun holster. Danny is worried about the kid who was trying to belong with the Tanglewood gang. He gets Danny to feel better, and gets him to work. Stella runs into Mac. Jane called. The DNA came back a mixture, the vic and a Johnny Lacerno, from Pelham Bay. Mac, Stella and Flack head to the mall where Danny said they liked to hang.

We see some kids in a sports store talking, and the trio come up to them. The kid they confront has stitches in his head, saying some kid came up to him outside of a sports club and whacked him in the head with it. He says he's pretty sure he knows who is behind it. Sports bar is in Yonkers.

Stella and Mac head there, there is sawdust and shuffleboard there. They question the bartender and ask if he was working when kids from Tanglewood and Pelham Bay were there. Someone looks at him and walks away. He asks if any memorabilia was stolen and the guy says "all I can say is if you wanna get cash out use that ATM over there": anted above the ATM is a case with a missing …something. Upon further examination it's a Mickey Mantle bat. They dust the case for prints and scan them with a computer Stella has. They come back Sonny Sassone, a Tanglewood Boy.

We see kids hanging out, with music, and dancing with it. Sonny is there. Stella, Mac and Flack are there and question him. He says the kid wasn't part of the Tanglewood Boys and shows his tattoo. He admits to being at the sports bar. And he admits to messing with it. Stella notices there was a new window installed (it was crashed) and that there was also a new set of tires. The Tanglewood Boys leave in his SVU and turn the music on. Stella notices a shoe impression with some dust. They take a print.

Danny and Aiden are at the office of Ross Lee and question him. He admits to being there. He says he will co-operate with them because he doesn't want them telling his wife.

Mac and Stella are back at the lab comparing show imprints. Sonny's imprints from his driveway match that found at the crime scene. Also Tony Baba found at the crime scene compared to those at the driveway. And Tanglewood Boy #2 was also a match. Problem is the shoes matched size but not pattern- they swapped out their shoes. So now they need the surveillance camera at the bar. But use the ATM machine from Billy Bats the sports bar. Paul is showing the tattoo to a girl, she isn't impressed. Sonny checks out his phony tattoo, he doesn't take any practice swings. The kid is there. So they are going to process his range rover.

Aiden and Danny are looking at the gem- it's not a diamond. Most likely from a nail. Flack walks in with a database hit; Ross Lee's wife is a registered with that car. They interview her. She isn't surprised her husband frequented the massage parlor. They ask to see her car, and she shows it to them. She claims she hit a fire hydrant and takes every bottle of the nail polish. They compare to the gem found and the car. The paint chips do not match from the car. Seems she really did hit a hydrant. And her nail polish isn't a match. Aiden goes over the list again and two days before Ross Lee, there was an A. Lee. His wife?

Mac and Stella are investigating Sonny's car. They spray it; there is an intense bleach smell. But there is nothing. On the dashboard is a bobblehead. Mac gets an idea looking at the bobble head and looks underneath its head. There is blood there. Jane goes over the sample with Stella and Mac- the blood sample was mitigated. There was too little and the bleach doesn't help.

Danny and Aiden are looking at the signature from the wife and comparing to the guest list. It doesn't match. Neither does the Ross Lee match to the wife's name (so it wasn't him signing for her) They check the signature behind the business card to the R. Lee on the guestbook that doesn't match either. So they ask who else signs, he says his secretary Tavia Greenburg.

They bring her in to interview. She denies going there, but they tell her that the writing sample she just gave them is a match to the A. Lee in the guestbook. She wanted to talk with the woman moving in on her boss, or her lover. They also found press on nails with a diamond stone missing from one. And the car she has matches the paint found at the site. She admits to everything, says that Ross and she were lovers and that she'd talk to his wife. Arianna came to the Tavia and suspected she was having an affair. She came and confronted Marta, and ran her off the road. She is going in for vehicular manslaughter 2.

Stella and Mac are at Sonny's shed. They look around and find a sander. Mac looks inside a toolbox- nothing. Stella looks on top of some shelves and finds another smaller sander, cordless and with blood on it. They bring him for questioning. He says he's going settle out of court. Mac sets up the story- saying they were going to initiate him. They were using him, but not going to let him become one. But he hadn't wanted him to kill the guy. So he took the sander and did it. Then the y killed him with a baseball bat. And he admits saying they did it. And he is all cocky about his gang. Mac is sure he'll go away. As he's being cuffed he mentions Danny, saying "you ask him about us, he knows all about us. Ask if he thinks I'll be going away." Mac looks confused at Stella. Danny was watching the questioning. He has what looks like tears in his eyes, his head bows down.
