Disclaimer: I don't own CSI, if I did Greg would be on CSI the whole darn episodes, not just one or five minutes with him! J

A/N: I don't know where I'm going with this story I just got the idea one day and decided to run with it, if it sucks, let me know!

It was early morning, very early. The tip of the sun was seen, the night of Las Vegas was almost over. Soon strips, nightclubs, and of course the pack heat of crowed people gambling will be closed. Yet Las Vegas was still active, 24/7. It was always alive, never died down………………

Four men were closing up soon, shift almost over, it was Friday night and they get their paychecks as soon as they finish cleaning up. Two of them, both 23 of age, were dumping the garbage in the dumpster as the other two, one 21 and the other turning 22 of age were setting the empty beer bottles in a stack next to the dumpster. The two oldest were friends, both in college and share dorms, the middle was also in college, yet only took this job to see the show girls behind the curtains and finally the younger one, same college as the two oldest, needed the money to pay back his college loans..

Four different men lives were about to change the next second as they laugh at a joke the youngster said, walking down the alley back to the back door when they hear muffles and banging. The four college students looked at each other and headed towards the muffles, hands on their hips were their guns were strap. They needed the gun in order a fight broke out or someone was hassling a striper. They gasp as they approach the site and saw a man letting go of a dead striper's throat Heather was her name.

The killer looked up and saw the four shocks, open-wide kids.  He started to take off when the four of them started going after him.

The youngest told the two oldest, "Call the police, we'll get him!"

The two stop and the first oldest took out his cell phone and called, while the other two ran deeper into the alley. The killer realizes he was heading towards a dead end and he needed to get pass the two kids that were armed. He pulled out a knife, hoping to slash the first one to reach him. It was the youngster yet he was fast as he saw the knife slash towards him, he rolled on the ground and turned around to see the killer lashing towards him. Scared, the kid lift his gun and shot the killer who was two feet in front of him, in the left shoulder. The killer fell back in pain just as the sirens were heard. The kid looked at the middle one and let out a scared smiled.

The four kids met together and watch as they pulled the killer in the hospital van and overhearing the police saying, "Make sure he stays alive for court."

The killer looked into the eyes of the younger one and said, "I'm going to get you boy, if it's the last thing I do!"

Of course they testify in court against him, which was even worse, because he got to know their names. They didn't have to go into the witness protection program since the man was going to jail forever, which was a good thing.

It's been seven years since the incident, and the four men went their separate ways, and all headed to Las Vegas for their jobs, all living a normal life. Until one day, the murderer ran away……….

Nick Stokes and Warrick Brown stepped out of the SUV. Both wearing black jackets that read "CSI" on the back. They walked up to the officer that was waiting for them at the French Palace a striper's place. The officer turned around and said. "The real action is in the back."

He lead them to the back of the building, where the yellow tape "Crime Scene do not cross" was tape across from the palace to another building, forming a square, and the two CSIs walked under the yellow tape.

They saw a garbage dumpster opened and they walked up to it.

"What happened?" Nick asked.

The officer replied, "A worker was throwing some trash in the garbage when he saw blood wiped on the edge, he stepped up and saw the body."

Nick and Warrick saw the smear of dried blood on the side. They stepped up on some little stairs and saw a white late twenties or early thirties male body lying on top of half filled garbage.

"No sign of blood pool." Warrick said, snapping a picture.

"The smear blood could be from the body, where the killer tried to dumped him in." Nick also said, snapping a picture.

"Are there any suspects?" Warrick asked to the officer.

"Yeah, the worker who found him and the boss, they were the only ones here since they're rebuilding the stage in there, opens again in two days." The officer replied once again.

Nick took out a q-tip and wiped the blood. "Guess Greg has something to do tonight." Nick joked.

Warrick shined his flashlight down the alley. "It doesn't look like he was killed here, no sign of blood."

Nick looked at the two men waiting to get the body out, "Okay guys take him out carefully."

They did so as Nick and Warrick check the alleyway for evidence.

"Maybe we should interview that boss and that worker." Nick said, after realizing that nothing was there.

Warrick sigh, "I hate when there's no evidence!" he shouted, as he remembered the serial killer that killed women and putted them in a pose.

They walked up to the officer and ask to see the two suspect.

They walked in to see to the boss moaning. They ran up to him.

"What happened?" Warrick asked.

The boss barfed up a pile of blood over their shoes and fell to the ground. Nick check for a pulse.

"He's dead."

"Poison." Warrick said, holding up a syringe.

"Where's the worker?" Nick asked the officer.

"I think he ran away."

Nick and Warrick looked at each other.

"Well at least we got a suspect." Nick said.

"Yeah," Warrick growled, "But we don't know who he is."

Twenty minutes away of the French Palace, another body was found. A male choked to death in the middle of an alley between two apartment buildings.

Snap-Snap!

Catherine took another picture of the death male db, while Grissom check the surrounding for evidence. They identify the male as a Jake Berenson, age 30, registered in Vegas. Born 8-24-73, died 10-3-03, three stories down of his own apartment.

"Well the murderer didn't drop him from three stories." Catherine said, noticing there is no impact of him hitting the ground from that high.

"No evidence around here, there's no door that leads to the alleyway from here."

"Expect for the fire escapes." Catherine said, "Which opens a whole variety of suspects for us."

"Well it narrows it down for us compare to all the people in the Las Vegas area." Grissom said.

Catherine kneeled down to get a better look at Jake's neck. "There is a huge bruise around his neck, but no actual hand marks, which probably means.."

"The killer wore gloves." Grissom replied.

"Grissom!" a voice shouted out.

Catherine and Grissom turned around to see Brass coming.

"Did you turn off your cell phone?" he asked.

Grissom looked down then glance up sheepishly, "Yeah sorry."

"Tell that to Nick, he's been trying to call you for five minutes. He said that he just got back from his crime scene and learned that you guys got a db twenty minutes away."

"Yeah, Why? Catherine asked.

"Well they said that a worker that called them in escape, killing the other suspect before running away." Brass sighs before continuing, "It turns out that he was gone for about an hour."

"We just got here ten minutes ago.." Grissom started.

"And the guy is still fresh, we check his temperature, hasn't been dead for an hour yet." Catherine said, "We could trace the phone call and see where the guy called us from, reporting a murder on the alley way."

"Where was Nick's db at?" Grissom asked.

"French Palace, db is Josh Denver age 30." Brass answered.

"That's almost twenty minutes away, yet in cars usually ten minutes tops." Catherine said she turned to Grissom, "Serial killer of thirty year old males or just a coincidence?"

"In my opinion there is no such thing as coincidence," Grissom started. "We take the body to the coroner, then we deal with this like two cases."

Catherine nodded, "I'll try and trace the call and see where he was or traveling when he called us." She started to walk but stopped, "But then again, maybe we should check and see what the victims both have in common.."

"Blood on the dumpster is your db, Josh Denver." Greg said.

"Well the guy died by strangulation and we found a scratch on the victims hips, still fresh." Nick said.

"Maybe it got there while the killer dump him." Greg replied, and turned back to his paper work that he was doing.

"Hey Greg, could you do me a favor?" Nick asked.

Greg turned to him, "As long as I get something in return."

Nick smiled and he handed Greg a piece of paper, "Could you find what these two victims got in common?"

"Well whose the other victim?" Greg asks, taking the paper.

"Grissom and Catherine's victim." Nick explained the worker escaping and the theory that Nick came up with, that the same guy killed the two victims.

Greg nodded, "Sure, gives me a reason not to do all these paper works."

BEEP-BEEP

Greg and Nick turned to the printer that had a paper printing out of it. Greg grabbed it and replied, "The drug in the syringe is Stovamringe, it's the new drug med that people use for upset stomach, too much causes them to throw up."

Nick nodded and was shock by Greg's fast reply on what the med was, "The guy cough up blood, which means-"

"He hasn't eaten anything for the past six hours." Greg interrupted.

"Yeah," Nick pager beeped he looked down at it, "I've got to go to autopsy for the boss, good luck finding what the two victims have in common."

Greg nodded, he turned on his stereo and punk rock filled up the air.

As he read the name on the paper, "Josh Denver and Jake Berenson." He got the strangest sense of déjà vu but doesn't know why..

A/N: Now it's time for you guys to Review!! I'll probably have the next chapter up in a few days…
