A/N: I know I have other things to finish, but this wouldn't go away until I wrote it.

Greg was wearing his trademark smirk as he picked up his guitar and faced his audience. He shifted his fingers to form the first chord of Welcome to the Jungle. The band started playing, as and so did he.

He made it through the intro without missing a beat, losing himself in the music. Greg started sing along and dance to music, fingers moving almost without thought. He jumped right into the solo as the break room door opened and he gained an actual audience, instead of the virtual one he'd been playing for.

Nick Stokes shook his head and tried not to laugh as Greg continued to sing, dance, and otherwise make a complete fool of himself while playing Guitar Hero. For his part, Greg was focused on what he was doing and hadn't made a mistake yet.

As he finished playing the last few notes, Greg noticed that he wasn't alone. Instead of being mortified, like a normal person, Greg just shrugged, "Told you I could've been a rock star."

Nick couldn't help but laugh at his friend. Trying to be the more responsible one, he warned Greg. "I know that it's a slow night and all, but Grissom really doesn't like it when people play video games on county time."

Greg rolled his eyes, "Grissom is…" Catching his boss' reflection in the cabinet, he continued, "A really great boss."

Nick forced back a laugh as Grissom himself spoke. "Save it. We've got a scene." He sounded a little rattled. "Brass said the killer left us one hell of a mess."

Shifting gears quickly, Greg nodded. "Did Brass give details?"

Grissom nodded, "Crime scene is at UNLV, Professor was murdered in her office." He paused. "Jim said it looked like our killer could be Jack the Ripper."

Nick nodded. It must've been pretty bad to unnerve the twenty-plus year veteran.

"We'll be ready in five."

Grissom nodded and headed for the parking lot. Nick and Greg joined him after a quick stop to grab their kits.

The drive to the scene was short, and very silent. In the backseat, Greg was dying for Grissom to turn on the radio or at least say something. The quiet was driving him nuts.

When they arrived on the scene, it was clear that Jim wasn't kidding; the office she was found in was a bloody mess, and the body itself looked as if Doc Robbins had autopsied her while she still alive.

A very pale David Philips was waiting for them. "Hey, guys. Cause of death seems obvious. It also looks like your killer took at least one major organ, probably more." He paused and frowned at Grissom. "Bears a strange resemblance to Jack the Ripper's victims."

"Unless you can put the time of death at a few centuries ago, I doubt he's a suspect, Super Dave," Nick pointed out.

"TOD is about three hours ago." Dave said. "I'll be able to tell you more after autopsy,"

The CSIs thanked him and got to work. Grissom and Greg took the perimeter, working their way in toward the body. Grissom studied the blood spatter on the walls, trying to picture how this happened.

The victim is sitting at her desk when she hears somebody knock on the door. She opens the door, thinking its student with a question, And it's likely that the attacker is a student, or at least somebody that the Professor doesn't consider a threat, because she lets him inside. They talk for a few moments and walk to the center of the room, where he pulls out a large knife. Caught by surprise, she doesn't put up much resistance until he plunges the knife into her chest…

Greg's voice seemed to echo his thoughts. "Looks like she knew her attacker. No signs of forced entry, and judging by these shoeprints, the attacker wasn't very big." He indicated a set of small, bloody prints.

Grissom nodded. "It could have been a student. Make sure you swab everything."

"This much blood, killer probably cut himself." Greg agreed.

Meanwhile, Nick went join Brass. The captain was waiting with the student who found the body. The student was a young, average looking college kid, brown hair and eyes, just shy of six feet tall.

"This is George Hunter. He found Professor Lee's body and called it in."

George Hunter himself looked pretty shaken by what he had seen. "Yeah, I was going to talk to her about the midterm. I set up an appointment." He stopped, trying to gather his thoughts.

"What happened after that, George?" Nick asked, trying to encourage him. He studied the student, who seemed to be in shock. After viewing that crime scene, Nick didn't blame him.

George took a shaky breath and continued. "I knocked, more then once, but she didn't answer the door. I tried the door, and it was unlocked. She never leaves it unlocked. I went in because I thought something was wrong. I was kinda freaked out, but I remember calling nine-one-one"

Nick nodded. "Did you touch anything?"

"No. I left as soon as I saw her, or what was left of her…" George was still pretty freaked out, Nick noted.

"Okay, good. Listen, I'm going to need your shoes."

"To rule me out, right?" Stokes nodded. " 'cause that's what Jen taught. Forensics, I mean."

Nick nodded. "So I don't have to explain to you why we need your DNA and finger prints."

"No problem." Nick briefly wondered if George might a bit too cooperative. After getting prints and DNA, he went to join Greg and Grissom.

He quickly explained what he had learned from George and Brass, adding that the killer may know something about forensics.

Greg shook his head. "Great. Some psycho cutting up his victims, and there's a good chance he knows a lot about forensics."

A/N: And there goes chapter 1. I know where I'm going with this, really. Anyhow, I need to start chapter 2. If you're nice enough to leave a review, I may post it in the morning, or at least as soon as I finish it. (hint)

Thanks for reading !
