"I can't believe her father would leave her alone like that!" Catherine exclaimed, "It's horrible!"

"Not kidding," Sara replied, "It's amazing she can live like that."

"Think she's hiding anything?" Brass asked as the Tahoe pulled out of the driveway and sped down the open road.

"I doubt it," Catherine said, "She doesn't seem like the kind who would lie, even to protect someone she cared for."

"Well she certainly wasn't worried or trying to protect her dad," Sara said, "Who can blame her with an asshole like that..."

"Now, now Sara," Grissom said calmly, "We don't know he's an asshole...yet."

"Oh get off it Gil," Catherine said, "If you were a father and your wife had been dead for years would you really leave your 14 year old daughter home alone for weeks at a time in Las Vegas no less?"

"No," Grissom replied.

"My point exactly," Catherine said, "Leaving a teenage girl home alone for weeks on end in Sin City isn't the best thing he could be doing for her. There are sicko's everywhere just waiting to find a girl home along like that."

"Well we promised not to say anything," Brass said, "And we wouldn't be setting a good example by betraying her trust."

"Still," Catherine said as the Tahoe pulled up into the crime labs parking lot, "It's just not right, being by herself 24/7..."

"Well, we'll keep an eye on her if that makes you feel better." Brass said.

"It will, thanks," Catherine said as she stepped form the Tahoe, "Alright, let's match some evidence."



Two hours later...



"Nothing!" Grissom threw down the folder Greg had handed him moments earlier. "Nothing matches, are you sure?"

"Positive," Greg replied, "The evidence you found at the scene holds no connection what do ever to the evidence to anything you found at Amy Walker's house."

"What about RAP sheets on Morrison or Walker?" Grissom asked Warrick who was sitting in Grissom's office, "Please tell me you found something.."

"Nothing," Warrick replied, "Neither of those guys even have a parking ticket, their both about as clean as can be."

"Mrs. Morrison?"

"Clean too," Warrick said, "Honestly there is nothing pinning her or David Walker to Morrison's murder."

"Have you checked Philip Morrison's records? Any business problems? Strange phone calls?" Grissom asked.

"Nope," Sara said as she walked into Grissom's office, "David Walker on the other hand was receiving fairly strange calls. In one day he received eleven calls which only lasted about a minute each."

"What day?" Grissom asked.

"Umm, the 26th of June." Sara replied, "I tried to track where the call had come from but it came up blank. Probably a prepaid cell phone card or something like that."

"So if we can find who called him we may have another suspect." Grissom said thoughtfully, "But who..."

"Hey Gil," Catherine said as she walked into the office, "I called the school that Amy goes to and talked to her teachers. She's one of the best students there, honest, hard working, and she's never missed a day."

"Did they know about her father?" Nick asked as he sipped a cup of coffee.

"No but they do now. They had no idea, mainly because they never had a reason to call her house."

"They plan on doing anything about it?" Nick asked.

"Well her home room teacher said she'd keep an eye on her and if things didn't look good they would call social services." Catherine replied simply, "But i think she'll be fine."

"So have we hit a dead end?" Warrick asked.

"It looks like it," Grissom said.

"No way!" Sara exclaimed, "There has to be something we've missed."

"Well where do you suggest we look?" Nick asked, "Unless we plan on getting a fine tooth comb and checking everything again we're pretty much sunk."

"Well then that's what we have to do," Grissom replied, "Get those combs out and start searching."

Everyone in the room sighed, "Where should we start?" Catherine asked.

"Let's start at the very beginning," Grissom said.

"It's a very good place to start," Nick snickered as he jabbed Warrick with his elbow.

"If you start singing like Julie Andrews I'll smack you," Sara said.

"Enough," Grissom said, "Let's get to the crime scene, We'll start at the warehouse and move out. There may have been things we missed on the first time around."

"You know in our line of work that isn't a good thing." Catherine pointed out.

"That's why I'm hoping we didn't miss anything," Grissom said, "If we did it could mean the end of the case."

But the only thing they had missed was a set of tire prints, fully intact, the CSI team went back to the labs and ran them through the computer.

"Mazda," Sara said as the results printed from the computer, "They match the partials we got from the scene the first time."

"Correction," Greg said as he peered through a microscope, "A black Mazda, probably old too."

"How'd you come up with that?" Sara asked.

"Paint chips," The lab rat replied, "By the way they look I'd guess that they came off when the car brushed up against a tree or something like that."

"Well that narrows it down the many thousands of people in the Las Vegas area." Sara muttered angrily, "Honestly."

"Wish I could be more help," Greg said, "But I'd need field work to..."

"Forget it Greg," Sara said, "You know I don't have any power over who works in the field."

"Can't help trying..." He muttered as he went back to his microscope.

Sara chuckled and walked out of the lab, Catherine quickly caught up to her, "Come on." The older CSI said, 'We're going to lunch."

"Oo where?"

"Some diner down the road." Catherine replied.
