Sara was leaning over the layout table reviewing the evidence from Jenna Matthews' case for what seemed like the umpteenth time when Nick rushed in, a bit breathless but with a smile on his face. "Brass just called. PD picked the boyfriend up at the airport."

Sara glanced up a bit bleary eyed. "You driving?" She had been staring at evidence and crime scene photos so long she knew that her eyes needed a break.

Nick nodded. "I'll meet you in the parking lot." He turned and disappeared as quickly as he'd arrived.

Sara stood up and tried to work out a few of the kinks that had begun to form in her neck and headed to the locker room to get her jacket. She began to mull over various theories that the evidence would support, but nothing so far seemed to gel. There were so many facets to this case that didn't make sense, that she was convinced they didn't have all the pieces.

Nick was already behind the wheel when Sara got out to the parking lot. She climbed into the passenger seat and fastened her seatbelt just as Nick pulled out into traffic. She smirked at him. "You know he's not going anywhere."

Nick noted her barb about his hurry and just grinned. "You know you want this guy as much as I do."

"If the evidence supports that." As much as she wanted this guy to be guilty so they could wrap up the case, there was a glimmer of doubt in her mind that he really was the killer.

Nick raised a single eyebrow. "He's the best suspect we have." He knew that they would have to support any charges brought against him with evidence, but he also knew that they couldn't have detained him if they didn't have some evidence that pointed his way.

"Right now he's the only suspect we have." Sara conceded the point, but she still had a nagging doubt that there was something about this whole thing that just didn't fit.

The pair lapsed into silence for the rest of the drive to the police station each of them lost in though. As Nick pulled into a parking spot, something occurred to Sara. She glanced over at Nick with a curious expression. "Did they pick him up coming or going?"

Nick looked a bit perplexed. "Huh?"

Sara repeated herself. "Did PD pick him up leaving Vegas or returning?"

Nick furrowed his brow. "Brass didn't say." And truth be told, Nick was so excited that they'd found their suspect that he hadn't asked either, but now that Sara mentioned it, he began to wonder himself. Either option spoke volumes about the probability of his guilt.

Sara pursed her lips together momentarily and nodded.

Nick smiled at her. "Hey, if he's innocent, the evidence will support that."

Sara had to chuckle softly; Nick's ability to read her mind at times was both comforting and a bit unsettling. She glanced over at him and smirked. "And if he's guilty, the evidence will nail his ass to the wall."

"Let's do this." Nick grinned at her. Of all the CSIs, he enjoyed working with her the most. The friendly competition between them served to push them both to think smarter and work harder, and he also just really enjoyed being around her.

They made their way into the police department in search of Brass. When they located the homicide detective, he looked frazzled. Nick looked at him curiously. "Jim?"

Brass flashed them both a sardonic grin. "We have a little twist."

"What's that?" Sara furrowed her brow.

"When we picked up Kevin Parker he wasn't alone." Brass pursed his lips together.

Nick's eyebrows arched upwards. "So what, he dumped Jenna for someone else?"

Brass smirked. "That's our twist."

Nick and Sara exchanged a confused glance.

"The woman he was with when we picked him up says that she's Jenna Matthews." Brass gestured towards the interrogation room.

Sara shook her head in confusion. "I don't understand. We did a DNA profile based on a known sample."

Brass gestured for them to follow. "I think it'll be clear in a moment."

As Nick and Sara entered the viewing area of the interrogation room, a very distraught woman who bore a striking resemblance to their victim sat at the table on the other side of the glass.

Brass gestured towards the glass. "This is Jenna Matthews, or rather Jenna Parker. Apparently, the reason she didn't return from Jamaica on schedule is because Kevin and Jenna decided to tie the knot while they were there. Our victim is her identical twin sister Camille."

Nick nodded his head in understanding. "Twins. Same DNA different finger prints."

"Kevin and Jenna were both in Jamaica at the time of the murder. Confirmed by United Airlines and the Immigration Service. Apparently, Camille was watching Jenna's cat while they were gone." Brass informed them.

Sara furrowed her brow. "So we're back to square one." At least this new information explained why they hadn't found suitcases, plane tickets, or a passport.

Brass nodded. "That's the way it seems."

Nick gestured towards the window. "Did she give any indication who might want to hurt her sister?" His mind was already shifting gears to try and approach things from another direction now that one possibility had clearly been elimated.

Brass shook his head.

Sara crossed her arms across her chest as she studied Jenna. "Maybe whoever did this thought Camille was Jenna."

Brass nodded. "We're looking into the possibility as well."

Nick glanced over at the expression on Sara's face. "Brass, I think Sara's right. If the killer hadn't killed the cat too, I'd say it might have more to do with Camille, but I think Jenna was the real target."

Brass considered the CSIs opinions for a moment and then nodded. "You just may be right."

Sara continued studying Jenna. "I still think that the cat is the key. You don't just kill a pet in the same way you kill it's owner unless you're trying to send a message. If Kevin Parker isn't the killer, then who else had access to her house and who else was that familiar with her cat?"
