When Grissom came into the breakroom he wasn't surprised to see Sara sitting there.
Even if it was before shift it looked like she was always at work. He got some coffee and sat down to wait for the others.
When they came he explained the case.

"Okay so we have one case tonight. One dead guy in a abandoned warehouse. Since there aren't any other cases we will all be working on this, cause we have a lot of ground to search for evidence. And I do have to say that the warehouse is where a gang has his so called home. The victim on the other hand was from a different gang. The police informed the gang so you shouldn't be surprised if they show up to see their death friend. Any questions?" Grissom said.

No one said anything so they all went on their way.

When they parked their Tahoes and gotten their kits they went inside.

"Okay, Catherine and Warrick, make pictures of the victim. Don't touch anything yet, the coroner isn't here yet.
Nick I want you to check outside for any tiretracks, weapons that could be dumped or other interesting things.
Sara I want you to walk all the way back and start looking for evidence in the rooms there.
Greg and I will start here and we will work our way to you in the middle." Grissom said.

They all got started.

Cath and Warrick started on making pictures of the victim and went looking for evidence close to the body.

Grissom and Greg were first checking the main hall, while Sara walked all the way to the end of the warehouse.

She saw that people were coming there often, because of all the trash and she spotted some drugs.
This should be the place the gang hangs out. She started investigating without noticing someone spotted her in 'their' home.

Nick on the other hand was aware of everything that was going on.
When he was checking some tire tracks from a car he heard some cars getting closer. "Oh no." He said and called Grissom and Greg. "I guess they know their friend is death." Greg mentioned.

The cars came closer and stopped right before the policecars. Brass saw they were planning on going in so he stopped them before they could destroy evidence that would help the CSI's to find the killer of their gang member.

"Guys stop, if you go any further you will only make it harder to them to find the killer. If you just stay out here someone will get your statements." Brass said.

A guy stepped forward. "Cant we just see the body for a moment? Just to confirm its our friend. We could help you, cause some gangs place the bodies of the people they killed in a special way, so that we know who did it." The guy said.

Brass looked at Grissom. "Well only a few and just go in and out without touching anything." Grissom said and lead 4 guys inside the warehouse.

"Cath, Warrick, could you step back for a second. They are here to help us a bit with the case. They need to see the body. They wont touch anything." Grissom said.

Cath and Warrick agreed and stepped back. They walked a few metres back to give the gang members some privacy.

Meanwhile Sara was still investigating and had no idea what the others were doing or what was happening.
She found some blood splatter in the back of the room so she moved her kit there.

When she was swabbing the blood, and unknowingly faced away from the door, she didn't hear people getting in.
That was, until she felt someone standing behind here.

"So you two are quick." Sara said, assuming it were Grissom and Greg and didn't turn around.
"You know, I found some blood here on the wall and im guessing this room is where that gang stays when they are here. What do you think?" She asked.

"Well I think you are completely right about that gang staying here." Sara heard a voice she didn't recognized and immediately turned around. There she froze, before her stood 5 large men.
They were covered in tattoos and Sara knew they were part of the gang.
Sara knew she was in trouble.

At the same time somewhere in the bushes Tom watched everything what happened in the warehouse on the little screen he got from his car.
He watched the CSI coming and he was mad his plan didn't work out and that he would possibly hurt innocent people.

But then his wish came true.
He saw the people who killed Dave and Alexa coming towards the warehouse.
The CSI people let them in!
He couldn't be happier.

But he didn't like what he saw on the other camera he set up.
He saw another gang entering the warehouse in the back.
They moved into their room.

But Tom saw a CSI getting into that room a few minutes before.
It was a pretty girl who looked a bit like his girlfriend Alexa.
He knew what kind of gang it was.
He had to save her before they could hurt here.
He switched back to the main hall and saw the gang he was targeting standing around their dead mate.

This was it.

He pushed a button.
