I don't own any of the characters that truly appear on the show, the only characters

That I own are the ones that I made up.

R&R thanks :)

I thought about this idea while I was busy doing something I LOVE- swinging, I think it's one of the best things in the worlds and I think everybody should do that. Anyway, I hope you'll like the story but you have to know that I don't know a thing about all the scientific stuff on CSI so I'm sure I'll make mistakes.

I hope you enjoy it!

The swing's secret/ chapter one: Crime scene

The body of David Trent, 10, was found not far from his family's house by someone who passed there on his way to work. It looked like a murder, a knife tore the kid's throat, and he couldn't do that to himself because he was right handed and the knife moved from right to left meaning somebody killed David.

Grissom, Catherine and Nick analyzed the scene it was pretty obvious that he wasn't killed there and they didn't find the knife.

"I guess we're done with the body" Grissom said, "I'll call the coroner to take the body" Grissom left.

"Are you OK?" Catherine asked Nick.

"Sure" Nick said "we should go talk to the family".

"Yeah, lets go Gris will join us later" They both went towards Brass who was talking to David's parents, the mother Alex was holding a one year old girl, David's little sister Jeanie, he also had a six years old brother Josh and a thirteen years old sister Rianne. Rianne wasn't sitting with her parents like Jeanie and Josh.

"Mr. and Mrs. Trent I am Catherine Willows and this is Nick Stokes we are from the Las Vegas crime lab" Catherine looked at Alex.

"You said you have another daughter", said Brass "do you know where is she?"

"Rianne, she's probably in the park," Alex said and pointed at the park's direction, she had tears in her eyes "she loves going there", she continued "she has this problem with people you see…" she stopped for a moment. Her husband, Trevor putted his hand around her shoulder "she's a very closed person, she doesn't talk a lot and…" she looked at Catherine "you don't think she did it do you?"

"We don't know" Catherine said and looked at Nick "we'll try to find who did it". She, Brass and Nick left the parents.

"I'll go look for the girl", Nick said.

"Yeah OK" Catherine looked at Brass "Grissom and I look in David's room, get Sara and Warrick they will talk to the parents and the kid".

"Fine", said Brass. Nick went to the park and Catherine went to Grissom and called him to go into the house.

*********************************************************************

Grissom and Catherine went into the house.

"Do you think the knife came from the house?" Catherine asked.

"We don't even know when he was killed, not by who and of course not where the knife came from".

"We can check, can't we?" Catherine went to the kitchen and looked at the box with the knifes "lets see if we can find some blood" she took all the knifes and putted them on the counter. She took something out of her kit (the thing that finds blood, makes it blue) and putted it on the knifes. "Grissom", she said, "close the blinds" Grissom did what she said and the room got dark. They looked at the knifes only one of them became blue on the edge. Catherine took the knife and looked at it, the blade was sharpened. Catherine and Grissom looked at each other and than at the knife.

"I think there's…" Grissom said and took the knife he took a magnifying glass from his kit and looked at the knife and then at Catherine "what?" she asked him.

"Look at this"

She looked at the place that Grissom showed her "is that a..?"

"I think it's a piece of skin" Grissom "looks like we maybe found the weapon, I'll go back to the lab you look in the kid's room, do you want me to ask Sara or Warrick to help you?"

"No, I'll be fine", she said, "call me as soon as you know anything".
