A/N: So forth another update before I disappear again to study. Finals coming up and NK2's latest chatper is still undergoing hell. I'm estimating it'll be more than sixteen pages...probably like, eighteen, maybe. And guess what? I've only done four pages. TT''

Forgive me if this is a pretty bad horror / mystery. I haven't tried anything of this genre for a while so that's why this crossover's going to be as short as possible. As in, probably two to seven pages long each chapter, etc, unlike NK2. I'm also assuming everyone knows the characters of CSI so I don't have to describe them as much. Everything's mostly going to be from their point of view.

I hope you'll enjoy! This chatper was sort of to set things moving. I got a lot of things planned for this fic, I just hope it all unfolds well. And please tell me if I have everyone in character! I haven't read enough CSI fanfiction to get everyone 'in character', yet. TT..

Read and Review please!

Act One

Scene One: The Crime Scene

A couple of hours had passed, and yet, Sara, Catherine and Warrick were still cleaning up the scene's vicinity. Grissom, Brass, and Nick had already left to consult with the lab back at headquarters, but it was alright. They regularly switched roles, so Sara, Catherine, and Warrick were used to their share this time.

Warrick sighed and walked out of the adjacent bathroom, inserting a Q-tip in its plastic holder. "Found some blood in the bathroom sink. I guess maybe our killer didn't have enough time as he thought."

"That would leave why one of the victims survived," Sara said. "Perhaps the killer thought he had finished with them already."

"Probably panicked," Catherine sighed. She dusted the side of an upturned, chipped table. "Broken wine glass, dead girl, injured boy."

"What did the boy look like when he was found?" asked Sara. Catherine carefully rubbed the area of the table with a Q-tip.

"Apparently lying half-naked on the ground underneath our vic. The only thing covering his privates was a long towel."

"Some decency," Sara commented dryly. Catherine shook her head and watched as the Q-tip glowed red.

"I got blood," she sighed. "But not as though it will help much. Two bleeding victims, blood in the sink. Most likely we'll have three different samples: two vics, and the killer."

"Except it will be hell to sort through," Warrick sighed. "Looked like it was a bad struggle in here. Vics and killer's blood could be anywhere…mixed, splattered…"

"Well, maybe we can help a little with that," Sara said. She ran her ultraviolet gun over the rub where the white-haired boy had been. White spots glowed in the blue light. "Would you look at that. Teenage boys never change." She bent down and carefully rubbed a Q-tip against one of the white spots, nearer to the speckles of blood. "We rope off where each blood sample was found. And match the semen that was closest in vicinity to the blood."

"That could work," Warrick said. "Blood in the sink could only be the killer's…after what those kids went through, doubt they were able to clean themselves up in the sink."

"And the only boy in this place will make things easier to differentiate," Sara smiled. She looked around at the ravaged bed, and her face fell. "Unless there were more than one…somehow, I doubt that that was created with only a twosome."

"Possible rape?" Warrick suggested grimly. "Whitey came in, tried to knock it on with our vic?"

"Wouldn't explain why he ended up with more wounds than she did," Catherine said logically. "And wouldn't explain why he was bleeding…" She winced and regained control of herself. "From there…"

Sara sighed and shook her head. "Sexual assault kit found no traces of semen in the girl. We'll check it out on the boy."

"You actually think he's the victim here?" Catherine asked. Sara nodded grimly.

"Well, he has to be one of them." She reckoned. "Maybe killer wanted to do it with him, used the girl as a hostage? A threat? A warning?"

"A gay killer," Catherine sighed. "Wonder how easily it will be to get one of those."

Scene Two: Suspect

"So…tell me what happened," Brass said. "What did you see?"

The brown curly haired girl sniffed and wiped her eyes with her laced sleeves.

"…I…I was just cleaning. I came in. Saw them. Saw…"

"Did you hear some sort of disturbance?" Brass asked. "Did you hear yelling perhaps? A fight?"

Maria shook her head, sniffing. "No… nothing. Just…it was quiet. The d-door was l-locked…I unlocked it…went inside…it was dark," she whispered.

Brass sighed and nodded. "And you didn't bother to call 911?"

"I did," Maria argued, her voice breaking. "A-after…"

"After you walked into the crime scene?"

"I didn't know," Maria explained tearfully. "Dark…it was dark! I r-remember…stepping on glass…and then…I saw them…he opened his eyes!" Maria burst into traumatized tears and buried her face into her hands. "I swear I didn't kill them! I didn't even really know who they were! They were such nice guests!"

Brass sighed. "Regardless, I'll have to take in your fingerprints." He pointed to one of the CSI men. "Wipe off your fingers, and go to them. I've got some more questioning to do."

Meanwhile, Catherine had found her way into the lobby. Throngs of people stood cluttered about, whispering to one another as forensic men and women wove their way in and out. With some help of the clerk, Catherine spotted a group of teenagers sitting in the lounge, their heads hanging.

With much difficulty, she pushed her way through the crowds. When they had parted enough for her to arrive in the corner, most of the little group had raised their heads towards her. Catherine paused momentarily to take a good look at each character.

There were four chairs surrounded by a circular coffee table. In the nearest, right-hand chair sat a young boy, very small. He looked no larger than five feet, if you did not count the possibly another foot of multicolored hair that shot up to the skies. His large eyes were purple and tearful, and the rest of his pale face resembled much of a child's.

Her eyes drifted away from the first boy. Behind the first boy stood a teenage girl, with shoulder-length brown hair and large blue eyes. Her cerulean orbs were glimmering with tears, and her fingers were twisting each other rather nervously. Next to her stood a rather built boy of dark descent; though his hair was blond, his eyes were a deep, rich purple. His expression was hard to decipher as his violet eyes met Catherine's blue ones.

A blond girl stood next to the tanned blond boy. At first, Catherine nearly mistakened her to be one of the hotel's dancers. Her hair was long and thick, her breasts were upheld within a white corset that was cut above her bellybutton, and her mini-skirt barely ended after the curve of her derriere. Catherine bristled slightly and continued.

In the next chair sat a tall teenage boy with blond hair, his head in his hands. Catherine inwardly shook her head. This must've been the lover, or the brother, or some relation of sorts.

A brown-haired guy looked up, looking at Catherine warily. His companion, a boy with long black hair tied back in a ponytail, also watched Catherine warily. Catherine cleared her throat.

"My name is Catherine Willows," she introduced herself, holding up her ID card. "I'm with the Las Vegas crime lab."

"Is Bakura-kun going to be alright?" the boy with the tri-colored hair asked immediately. Catherine turned to face him, his violet eyes shining with tears. "Will he be okay?"

"What about Shizuka?" the boy with the brown hair demanded. "What about Shizuka? Where is she?"

Catherine raised the ID card of the victim. "Is this 'Shizuka'?"

The blond haired boy with his heads down looked up. His eyes widened and Catherine noted how significantly paler he had turned. The two girls turned to face the picture, and sniffing, the girl with the brown hair nodded.

"Is…Shizuka-chan…alright?" the brown-haired girl asked in a whisper.

Catherine sighed and lowered the picture. She carefully avoided the question momentarily.

"How…are you all related, to Shizuka?" she asked. "What are you doing here in Vegas?"

"We…we're Shizuka's friends," the short boy croaked. He wiped his eyes. "We…we come from Japan…we came here for summer break and arrived here just a couple of weeks ago…"

"But you checked in here a week and a half ago," Catherine said. "Where were you all before?"

"Tourist attraction," the blond haired girl said dully. "They stayed with me."

Catherine moved her gaze towards the blond girl. "I see. And you are…?"
"Mai," the blond retorted coldly. She flipped back her long blond hair. "Mai Kujuyaki, or Mai Valentine, if you will. I used to live here in Las Vegas. You can find my American citizenship under any file here."

"I'd rather prefer to see your ID," Catherine said. Mai sighed shortly and glared at Catherine.

"What would you need my ID for? I did nothing," Mai said haughtily.

"Regardless, I still want all of your ID," Catherine responded calmly. "You are all related to Serenity, am I right? Therefore, I will have to know everything about you."

"No one would want to hurt Shizuka," Mai said venomously. "She was a sweetheart! Everyone here loved her!"

"She was so kind! So sweet!" the brown-haired girl cried. "She was like a sister to me!"

"Calm down," Catherine sighed. "There's no point in getting uptight right now. All I want are your names, and for you to answer some questions."

"We don't need to answer any questions until you tell us what has happened to Shizuka!" Mai shot. "Girl, you've got some problems if you---"

Catherine raised a hand and shot Mai a glance. The other blond fell silent.

"I know you're all upset," Catherine said quietly. "But this is protocol. I need to know your names and your relations to Serenity."

"Serenity isn't her real name," the little boy in the front said quietly. He looked up, his purple eyes shimmering with tears. "It's Shizuka. Katsuya Shizuka."

Catherine arched an eyebrow. "Could you care to tell me why she has different names on different ID cards? And you are…?"
The little boy bowed his head. "Yuugi. Yuugi Motou."

"We all have different names on our ID cards," the brown-haired girl spoke up, her voice wavering. "We are foreign students, coming here for vacation. We were given English names and ID from our school to 'fit in'."

"Strange system you people have," Catherine commented. "Where do you all come from then? And you are…?"

The brown haired girl bowed slowly. "Anzu. Anzu Mazaki. My English name is Tea Gardner."

"Alright, Anzu," Catherine sighed. "Let's start. I'm aware that you all share the same room with Serenity?"

"It's a connected room, really fancy," Mai explained softly from her corner, not even sparing Catherine a glance. "We have nine people here. Shizuka-chan, Anzu-chan, Yuugi-kun, Bakura-kun, Honda-kun, Ootogi-kun, Malik-kun, Jonouchi-kun, and me. Four bedrooms; one of us had to sleep out on the sofa."

"And who's room was the one that Serenity was found in?" asked Catherine.

Anzu bit her lip and looked away.

"How is Bakura-kun?" Yuugi piped up. "How is he? I saw him being carried out on a stretcher! What happened to him?"

"What happened to both of them?" the black-haired ponytailed boy demanded from the corner. His green eyes were vivid with anger. "What the hell happened to them?"

Catherine shook her head. "I'm afraid I can't tell you much at this stage. Your friend…Bakura, is it?…has been moved to the nearest hospital."

"But---"

"Look," Catherine bent down and raised up her kit. "I know this must be all hard on you. And it's chaotic here. But I want you to all co-operate with me. After we go through this, I promise I will keep you updated about everything as much as we can. As soon as everything clears up a bit, we'll contact her next of kin. Your rooms are all shared and connected, am I right?"

Everyone nodded.

"Okay. This means that any one of you had access to Serenity's room where she and her friend were found. This means…" Catherine opened up her kit. "Everyone, raise up your hands and open your mouths."
