Grissom made his way down the hall from the break room toward the lab where Greg was analyzing samples from the bus crime scene. Loud noises, which Grissom could only assume Greg called music, blared from the room. Grissom walked over and turned the volume down. Greg, who had been dancing around the lab as he worked, stopped mid-step and turned around. "Hey, boss, what can I do you for?"

"Greg, this is a place of business, not a dance club." He answered with a raised eyebrow.

Greg quickly shifted gears, "Ok, I'm assuming you're here for an update on the case. Turning the ZZ Top CD down aside. Anyway, I've been analyzing the blood on the fabric from the seat your vic was found on. The blood is from a single donor. The vic's. I've also been analyzing the blood from the vic's clothes. There I found two donors. The vic's and a mystery donor. I ran the mystery donor through CODIS and it came up empty. Now, something interesting I did find was a stray fiber that didn't fit into the whole bus scenario. It is a black triangular fiber, synthetic, upholstery most likely, but not from the bus, the fabric from the bus seats are blue. Also, no DNA. I also found some hair, not unusual in a man our vic's age, but this hair is non-human. Appears to be feline in nature. Both were found on the underside of your vic's tie." Greg handed Grissom a printout with the detailed analytical information on the samples.

"Thanks, Greg." Grissom replied looking over the data.

"That's what I'm here for, boss." Greg smiled. "Let me know if there's anything else I can do for you. Greg's my name, DNA's my game."

Grissom leveled a gaze at Greg silently asking if he was done yet.

"Well samples call." Greg turned and went back to what he was working on.

Grissom took the data and walked out of the lab and down the hall towards the break room.

Nick and Sara finally arrived at work. As they walked down the hall toward the break room, they exchanged nervous glances at each other, knowing they would have to talk later about what had happened at Nick's. As they entered the break room they found the rest of the team was waiting.

"Nick. Sara. Nice of you to join us." Grissom raised an eyebrow and noted that Sara wore the same clothes that she had left in that morning. "How's the video analysis coming? I want to bring the bus driver in so you can over it with him and try and put some names to faces."

"Almost done, Grissom. Warrick was checking with LV Transit. Apparently, most bus riders use a card that acts as a credit card. It keeps track of how much they still have on their account. So we can track who was on the bus from that." Sara explained.

Nick interjected, "Yeah, also, we learned that the drivers have a log they keep that tracks how many people get on at each stop, and they have an onboard computer that tracks all transactions for a particular stop, so we should be able to tell who got on and when, except for cash fares. But it also keeps track of how many cash fares they have per stop. We're just waiting for Warrick to get us the list."

Warrick responded to the unspoken question, "I'll have it in about an hour. Brass was getting the warrant and then we were going to head over there."

"Good work." Grissom replied. "Oh, Nick, Greg found some fibers and a hair you might want to take a look at. We're going to need to get samples of fibers from the vic's home, car, and office to compare them to. You might want to ask Catherine for help on this since she's already met the vic's wife. I'm sure you'll have no problem getting any warrant that you need, Mobley is hot on this one and the mayor isn't too far behind. Sara, I'd like you to print out what you've got and get with Warrick about that list from LV Transit. Once you have that, have Brass pick up the driver and you can start going over the pictures with him to see if he noticed anything unusual from his passengers."

"Sure, Gris." Sara replied, a bit relieved to not have to work with Nick all day.

"Yeah, thanks, Gris." Nick added, also a bit glad that he could concentrate on work and not worry about Sara for a while.

Catherine took in the whole exchange silently and inwardly chuckled. She was going to have fun grilling Nick about Sara. She'd make it long and drawn out.
