I'm setting this fanfiction between season 6 and 7, so Warrick, Grissom and Catherine are still there. And I changed Greg's age from about 30 to 26

CBS own CSI I own nothing, sadly. The only thin I own is the character Max Mackay but I wish I owned Greg :(!

The Las Vegas nightlife was in full swing the casinos and clubs were full of people enjoying Sin City and everything it has to offer. A mysterious man walks down the strip eyeing up the many women he passes before heading into one of the many Vegas Gentleman's Clubs. In the club images flash from dozens of screens surrounding the bar the mysterious man scans the crowd of dancing people as if he is looking for someone in particular then his eyes land on a young blonde woman at the bar, she seems shy and appears to be alone. The man just smiles to himself as if he is a hunter who has found his prey. As he walks over to the blonde her eyes widen in surprise hinting that the mysterious man is very good looking. He leans in close to the blonde and whispers something in her ear, smiling the blonde invites him back to her place he just nodded to agree.

Fast-forward the two are now just outside the blonde's apartment door but his lips are on her neck and his hands slide up her dress, the distraction causes her to moan with pleasure. She giggles as she pushes him away slightly to open the door. The both walk inside the blonde's apartment and what started as the blonde's best night of her life quickly changed as soon as she closed the door. The man grabs her hair and threw her to the floor and reveals a knife he had hidden in his jacket, this causes the blonde to scream and try to crawl away but the mysterious man jumps on her pinning her to the floor. As the blonde begs for her life, tears run down her face. But the man is unmoved by this in fact this just gives him pleasure and let him feel like the animal he knows he is. He looks into her eyes one last time and growl in an inhuman way before driving the knife into the blonde's chest.

Greg's eyes shot open, sweat dripping from his face; his heart was racing a mile a minute. His whole body was shaking, frighten by what he dreamed it was nothing liked he'd dreamed before it felt too real. But what disturbed him more was the pleasure he felt when he hurt that poor woman he dreamed. A beeping noise caused Greg to jump slightly but he soon realized it was just his alarm clock and that he needed to get up and get ready for work but he couldn't shake the unnerving feeling that things were only going to get worst much, much worst.
