Cath frowned, as a cup of coffee materialised before her eyes. She smiled at Nick and thanked him. She had just gotten the results back from the purple fibre on the body; it was satin. This had confused both CSI's as they had assumed the killer was male. She got up from the trace/analysis computer and followed Nick to the morgue.

"Good morning Catherine, Nick, no prizes for guessing your vic's COD. Exsanguination due to the laceration to her throat. The carotid artery is completely severed, using what looks to be a very sharp tool. My guess would be a scalpel or other medical implement." Doctor Robbins replied, gravely.

"So we may be looking for a doctor or surgeon?" Nick said, surprised.

"Yeah, I'd say so looking at the precision of these wounds, it looks like they are very skilled with a knife," Robbins responded.

"Anything else probative that we should know? Did you make a positive ID?" Catherine requested.

"I couldn't get any prints, the tips of the fingers have been burned off, but I've sent for dental records. The only other main thing that I can think to tell you is that she was already living on borrowed time. She had a cancerous tumour behind her right eye, I removed it for you," Robbins placed a metal dish in front of the CSI's.

"Did you run a SART kit Doc?" Nick asked.

"Yes, there was evidence of sex in the last 48 hours but it was consensual. Usually, when sex occurs, abrasions from around 11 o' clock to 1 o'clock, but during rape, there would be evidence of trauma at four to six o'clock and there is none here. I tried to get you DNA but whoever she had sex with wore a condom, sorry," the doctor concluded.

"Okay thanks Doc, we need to run the hair to see if we can get a match in CODIS," Catherine said to Nick, sighing.

"Yeah, catch you later Doc," Nick replied. Cath ran the DNA sample from the hair and waited. CODIS bleeped as Catherine had a match.

"Kelsey McIvers, cocktail waitress and the New York, New York Casino," Catherine said, curious.

"Landon kept that one quiet, why would a cocktail waitress be in our vic's room? Friend maybe?" Nick proposed.

"Yeah maybe, I'll ask Brass to bring him in to explain why he didn't tell us a member of his staff knew the vic," Catherine replied, before calling Brass on her cell. She finished the call with a smile on her face, Brass had already brought him in and he was in interrogation room one ready for them. As soon as she left the lab she bumped into Brass.

"Oh hey, can you bring in Kelsey McIvers for questioning?" she enquired.

"Oh, she's already here," Brass chuckled.

"Great, lets go find out what she was doing in out Jane Doe's room," she replied, relieved to be getting somewhere at last.

"She's on Doc Robbins' table, Sara and Greg are working the case now," Brass laughed.

"Damn it! Why do the only useful people in this case always seem to end up dead or missing?!" She sighed, exasperated.

"Hey, I'm not dead!" Brass' smile grew wider.

Catherine smiled wryly; "Is Landon is interrogation?" She asked.

"Yeah room one," Brass answered. Catherine strolled down the corridor towards the interrogation room; she peered through the door and entered. Landon was sat at the table, staring into space; he didn't even look up when Catherine walked in.

"Mr Landon, tell me about Kelsey McIvers," Catherine pried.

"She's a cocktail waitress at my hotel, nice girl, tall, pretty," He replied.

"She was found dead, dumped a few miles away from Lake Mead," She said, her eyes narrow.

"No. Are you sure it's Kelsey?" He replied, shakily.

"We made a positive match to her fingerprints. There was a hair on the victim from your hotel. It was Kelsey's. Did you know the victim?" Catherine asked.

"Only her name from our hotel records. The room was registered to a Lola Jacobs; I think that was the woman who was killed. I don't know why Kelsey would have been in her room, unless they were friends," Landon replied quietly. Just then Doctor Robbins entered the room, a report in his hand. He left the report with Catherine, nodded at her and Nick then left.

"The victim was Lola Jacobs, 19 from Newark New Jersey, she was here on vacation," Catherine read from the report.

"Oh now this is interesting, she was having a relationship with Kelsey McIvers, and now they are both dead, how strange," She smiled bitterly. "Well that's motive for someone out there. Possibly you Mr Landon." Catherine added.

"No not me Miss Willows. I have no problems with homosexuality, that's not my business. Especially not a reason to kill someone," Landon replied.

"Then you won't mind providing us with a DNA sample then will you?" Catherine smiled.

"Sure whatever you need," he smiled mock-politely. Catherine took an Integriswab from her kit and brushed the inside of his mouth.

"Thank you," She said lightly. Her cell began to ring and she answered;

"Willows,"

It's Brass. There's a good chance the hotel manager didn't kill your victim.

"How so?"

New victim, Jenny Phillips, found in her bedroom at the Tangiers, her throat cut, and that's all I know until you guys get here.

"Ok I'll grab Nick, see you soon," She clicked off.

"We have reason to believe another murder has been committed and since you have been in our custody you cannot have committed it, but we will be in contact with you again depending on what your DNA tells us, so stick around," Catherine said, somewhat harshly. Catherine left the interrogation room in search of Nick. She found him in the break room with Warrick.

"Hey there stranger, you back on shift now?" Catherine smiled at Warrick.

"Yeah, I'm back," He laughed.

"Grissom's put me on that hit and run out by Lake Mead, guy ploughed into a tree, with a man simultaneously. By hit and fun I mean he crushed the guy, and then ran off somewhere," He chuckled dryly.

"Some things never change, are we going somewhere?" he asked.

"Yeah, second murder at the Tangiers, same MO," She replied.

"Great," Nick said flatly, "Later Warrick,"

"Later man," Warrick laughed to himself.

"So what's this about?" Nick asked.

"Brass called, Jenny Phillips was found in her hotel room, throat trisected," Catherine answered.

" I think we've got ourselves a serial," Nick replied.

"I think you're right my friend, and we are hot on their tail," She smiled wryly, Nick smiled back at her;

"Yeah. You can run, but you can't hide,
