A/N: Thank you to everyone who's reviewed so far, I really appreciate it J

Nick looked at the object in his hand, turning it over to see it from all angles. "Why didn't she call 911 if she had her cell phone with her?" He asked Sara in his southern drawl.

"Maybe she didn't have it with her. Maybe she wasn't conscious." Sara replied, handing him a bag to place the cell phone in.

Nick frowned. "It's like she just lay down and died. There's no blood anywhere except where the body was."

"There's no nothing anywhere, except for where the body was." Sara told him, frustration evident in her voice. "This is ridiculous, there's nothing here."

Nick sighed and switched off his flashlight. "We're done in here, let's move on. Kitchen's the last room right?"

Sara nodded. "Yeah." She replied, heading out of the living room and towards the final room they had to check. "So, have you seen Greg? Is he okay about this?"

Nick shrugged, gently pushing the kitchen door open as they reached it. "He seemed fine. So did his sister too."

Sara frowned, walking into the room. "You saw his sister?" She asked, placing her kit on the kitchen table.

Nick nodded, making his way over to the far side of the room. "She came and told him in the lab. Me and Gris were there."

"What did she say?" Sara asked, beginning to check the cabinets nearest her.

"She just walked in and was like 'Hey Greg, mom's dead. See you later'." He shook his head, pulling his flashlight back out and shining it onto the work surface in front of him. "It was weird. She just said it, left, and he just kind of nodded and carried on working."

Sara stopped and turned round to look at her teammate. "You're kidding? Neither of them was the least bit upset?"

Nick shook his head, moving along the surface to the sink. "Nope. He followed her out though. Came back and still seemed fine. Even when he found out she'd been murdered."

Sara frowned. "He got any other siblings?"

"Yeah, apparently he's got two ol—hold up." Nick paused mid sentence. "Sara, come have a look at this." He asked her, standing back so she could get a closer look.

"What?" She asked, frowning.

Nick pointed to the cloth in the kitchen sink. "See that?" He asked, picking it up with a pair of tweezers.

Sara stared at the green cloth in his hand. It had a reddish shadow on it, with a darker stripe down the middle. "Blood?" She questioned.

"Looks like it to me." Nick replied, Sara nodded and walked over to her kit, pulling out a small bottle. "Look's like somebody wiped a knife clean." He commented, his eyes searching the rest of the room.

Sara looked up from the cloth and held it towards Nick. "Positive for human blood." She told him, showing him where the cloth had turned bright pink.

Nick nodded and took the cloth from her, placing it flat on the work surface. "Knife block." He stated, pointing to the wooden object next to the toaster. "What do you wanna bet the weapon's one of these?" He asked, pulling the six knives one by one out of the block.

Sara smiled and shook her head, watching as he held them up to the stain. "That looks like the one." She nodded slightly to the knife in his hand, as he held it up to the stain.

"Fit's perfectly." Nick agreed.

"We may have just found our murder weapon." Sara nodded, then looked down to the floor and scanned it with her eyes. "So, if the murder weapon's in here…" She began trailing off.

Nick followed her gaze to the floor. "Then someone had to come in here to put it back." He continued, catching onto where she was going.

"And maybe, we can lift some prints." Sara finished, smiling.

"Let's do it."

"Hey Warrick man," Warrick turned at the sound of Nick calling his name, to see the smaller man heading towards him down the corridor. "Evidence from Greg's parents place." Nick told him, following his gaze to the evidence bags in his hands. "Do you know if we give these results to Greg to be tested?" He asked.

Warrick shrugged. "I dunno man, conflict of interest and all that."

Nick nodded. "I know, but he's the best DNA guy we got. He didn't seem all that bothered, maybe it's okay if he does."

Warrick shook his head. "I dunno Nick. I doubt it. Brass seems to think he had a hand in this. I'd check with Griss."

"Greg?" Nick asked, disbelief evident in his tone. "Brass thinks Greg had a hand in this?" He paused. "Greg Sanders?" He repeated.

Warrick nodded. "Don't ask me man. It's crazy."

"Okay, I'll go ask Grissom." Nick replied. He paused before leaving. "Greg Sanders? A murderer?"

"Say it as many times as you want Nick, it's not gonna make it come true."

The two older men jumped at the sound of the third voice. They turned to see Greg leaning against the doorframe of the lab. "Greg." Nick said seeing him.

Greg nodded. "That's my name Nick… don't wear it out." He replied dryly. "Do you want me to run those for you?" He asked, gesturing towards the bags.

"How long have you been standing there?" Warrick asked, ignoring the tech labs question.

"Long enough." His reply was short and tense. "Do you want tests run on those?" Greg repeated, turning his attention back to Nick.

"Uh… well I'm just gonna go show Grissom what we found and see if it's worth running tests." Nick told the younger man, hoping his response was convincing.

Greg stared at them silently for a minute. "How did she die?" He asked quietly after the pause.

Nick shifted from one foot to the other and Warrick averted his gaze.

"She's my mother. I think I have a rite to know how she died." He stated, a hint of anger in his voice.

"She was stabbed." Nick said eventually.

"Once?"

Warrick nodded.

"Okay." Greg said quietly. He paused for a moment; running his tongue along the edge of his teeth, then spoke up. "I didn't do it." He told them firmly, before turning and walking back into the lab.
