Back at the lab, Calleigh was joking with Eric and Walter at the reception desk, when Horatio came through the elevator. "Guys, lets meet in the conference room in 5 minutes its important." he said walking past them to the DNA lab.

Maxine was typing on the computer when Horatio came, "Hey, Horatio what can I do for you today?"

"I need you to run these for me and tell me everything you can about this person. I need to know ASAP." He said handing her the paper that Natalia found earlier.

"Not a problem, I will run them now." She said getting ready to start the tests.

Horatio nodded and made his way to the conference thru the glass he could see Frank, Calleigh, Eric and Walter all sitting in there talking, just before he was about to walk in he saw Ryan come through the elevators. "Mr. Wolfe" he yelled waving he over to the conference room.

"Okay..." Horatio trailed off looking at everyone "Where's Natalia?" he asked.

"She must be stuck in traffic. I left the scene a few moments before her and the causeway was pretty packed." Ryan said.

"Okay, we will just catch her up when she gets here." Horatio continued "I called you all in here because these murders are becoming more serious. Our killer has moved up from killing prostitutes and homeless people he is moving up to bigger people, people that are more likely to be reported missing, his is getting more comfortable, and he must be stopped. Right now four people on this case will not cut it anymore, I need all of you to help." Horatio said.

"Not a problem H, what do you need?" Eric said.

"Well up till now, our killer has been leaving clues to who the next victim will be. We didn't get the clue for Mr. Clayton because the owner of the funeral home thought it was another threat from one of the local gangs. Mr. Clayton was the lead software development engineer for Xbox live." Horatio said.

"So his next victim will be someone who is in the public a lot, or has a lot of authority." Calleigh added.

"That is correct. At the scene today Natalia found a paper that blood, hair and a used Kleenex probably from his next victim. I gave the samples to Maxine and she is running them right now." Horatio said.

Horatio didn't get the chance to continue his statement when Maxine came into the room pale with wide eyes.

"Miss Valera?" Horatio asked.

"I ran the DNA samples you found at the scene..." she trailed off.

"And?" Eric said leaning forward in his seat.

"All three samples are a match to... Natalia..."

Walter grabbed the paper from Maxine's hand to look for himself. "She's right," he said.

Ryan got out his phone, "I'll call her cell," he said punching in the numbers.

"I got her house," Eric added.

"I'll try dispatch," Frank said.

Ryan hit send and he listened as the phone rang hoping that she would pick up. But no luck, her phone went to voicemail. "Hey, it's Natalia leave a message after the beep and I'll call you back as soon as possible." Ryan heard the beep, "Hey Talia it's Ryan, call me back when you get this." He said before hang up the phone.

"She didn't answer her house phone." Eric said putting his phone down.

"Same for me" Ryan added.

"Dispatch didn't get a response from her either."

"Okay guys lets not panic, we will find her. Ryan and Eric I want you guys to go back to crime scene. Calleigh and Walter I want you two to stop by her house, and her sisters' house maybe she might be there. Frank go downstairs and listen for any unusual activity and I'll stay here just in case she shows up." Horatio said. And with that the CSI's went there separate ways.

All the way to Natalia's house Calleigh tried to calm herself down. She kept telling herself that Natalia was okay, probably stuck in traffic and her hearing aid was malfunctioning so she couldn't hear the phone the ring. But those thoughts were short lived because soon images of Natalia tied to a chair shot and stabbed started to fill her head. She became so disgusted that she felt like throwing up, she felt her foot go closer to the ground as Walter and her raced to her Natalia's house.

Beep Beep

Brian pulled up into Nathan's custom auto car shop on Hialeah Hia Gardens Blvd. He got out of car and was greeted by his friend and owner of the shop Nate, Brian raised his hands, "And you said I couldn't kill two birds with one stone" he said with a grin.

Nate just smiled as he wiped his hands and walked up to Hummer. "You are unbelievable Brian, pop the hood."

Brian popped the hood, and walked in front of the car with Nate as they both looked at it. "So does this put me ahead of everyone else?" Brian said with a smile.

Nate made a face and backed away from the Hummer and walked around to the side to see the Miami Dade Police Department seal on the door. "This is cop car, I can't take this."

"Why not, this has all the parts that you need the lowest part on this is car is $100,000." Brian said.

"Yeah, it's fucking cop car Brian! look at the engine this thing is riddled with GPS tracking units. It connected to everything in this car. The engine, the brakes, the air conditioner, everything." Nate said in a raised voice.

"Holy shit" was the only response Brain gave looking closer at the engine.

Looking in the passenger seat Nate paused "Tell me that is not the cop that was driving this car?"

Brian just looked at Nate and smiled.

"You need to get this shit off my lot now! I already have the cops breathing down my back for this being a chop shop, I don't need this added on."

"So, what's the big deal?" Brian said.

"What's the big deal? Were not listening about the GPS? The cops will know everything about this car, where it's been, how fast she was going, they probably know if this bitch is wearing her seatbelt. They are probably tracking this car right now... Get rid of it!" Nate yelled.

"Fine" Brian said under his breath.

"And don't talk to me till you get rid of ALL of this." Nate said point to the car and Natalia.

"Okay, you know I miss the old you. The you that didn't care about anything, the new you is a punk little bitch." Brian said before he got back into the car.

Walter and Calleigh pulled up the Natalia's house; Walter got out and walked up the front door. Calleigh took her time, she pulled out her phone and instead of calling Natalia's house phone she called her house. The phone went to voicemail "Hey Nat, it me please call me when you get this. We all worried about you."

"She's not answering." Walter said raising his hands, "do you know where her sisters live?"

"No" Calleigh said shaking her head, she was lying. She felt a pit at the bottom of her stomach, this was not the time and place to lie. Natalia was missing, she could be in the hands of Horatio's killer, and she was lying about not knowing were her sister's lived. She had been to both of their houses for Christmas, New Years and Natalia's niece's and nephew's birthdays. Calleigh took a breath to tried to think of a lie to help her. "Wait! I helped find her sister Anya, I think I still have her phone number in my phone." She looked down at her phone, "I still have her address too" Calleigh said as they raced to the Hummer.

Eric and Ryan made it back to the back to the crime scene, "Natalia's Hummer is still here. Maybe she's inside." Eric said looking around.

"Yeah" Ryan said as he drew his gun and walked through the door. "Miami Dade PD! If there is anyone inside identify yourself!"

The room was quiet, the two men made their way further back into the funeral home. "This is where we were all morning." Ryan said looking around.

Eric looked around till a flash caught his eye, "Ryan" he said nodding to the chair where Mr. Clayton was found tied up.

"Oh, god" Ryan said raising his hand to his mouth.

Eric clenched his jaw in anger as he pulled out his phone. "H, it me... Yeah we found something... Her Hummer is outside and back at the scene we found something... We found her badge, gun, hearing aid and a jump drive... Okay" Eric said as he hung up the phone.

Walter and Calleigh made it Anya's house in record time, the whole way there they were calling her but she wasn't answering her phone.

"Do you think the killer got her family as well?" Walter said.

Calleigh closed her eyes, angry that Walter had to add that image to her mind. "I don't know Walter, just keep calling and don't stop till someone picks up." Calleigh said in a firm voice.

Once at Anya's house they saw her in the driveway taking out a bag of groceries. Calleigh had a sigh of relief when she saw that Anya was okay. "Hey Calleigh what's up?" she said with a smile that disappeared quickly when she saw that Calleigh was in no mood for small talk.

"Why haven't you been answering your phone?" Calleigh demanded.

"I needed to go grocery shopping and I left my phone at the house. Sorry, is everything okay?" she said walking into the house.

The three made it into the kitchen where Anya grabbed her phone and saw that she had 27 missed calls all from Calleigh. "Jesus Cal, what the hell?"

"Natalia is missing, has she called you at all?" Calleigh said.

"We spoke yesterday right before she went..." Anya paused and looked Walter, then closed her eyes and bit her lip. She silently punished herself for almost slipping Calleigh and Natalia's secret.

"Before she went where?" Walter demanded.

"A girlfriend's house" Anya shuddered.

"What's her friend's name?" Walter asked taking out a pen and paper.

"Don't know she didn't say." Anya said while exchanging looks with Calleigh.

"Well can you remember anything?" Walter continued.

Anya just shook her head. At that time both Calleigh and Walter got a paige to return the lab.

Sighing, Calleigh looked at Anya "Tell Christine from me, and if you hear anything let me know immediately regardless what anyone tells you. You understand."

Anya just shook her head again, and with that both Walter and Calleigh left and made their way back to the lab.

In 10 minutes Calleigh and Walter were back at the lab, getting off the elevator they looked around till they found Eric, Ryan, Horatio and Frank in the AV lab.

"Hey what's up?" Walter said looking at the screen.

"We found Natalia's gun, badge, hearing aid and this jump drive at the scene along with Natalia's Hummer." Eric said handing Calleigh a folder.

Without hesitation Calleigh grabbed the folder and began to thumb through it.

"What's on the jump drive" Walter asked getting closer to the desk.

"Well it's not just any jump drive, it's a dongle." Dave said without taking his eyes off the screen.

"A what?" Walter asked.

"It's a software protection device, you put code or a program on here that you want to protect. But thing is about this one is we have three tries to guess what the password is," Dave with sigh.

"What happens after three tries?" Eric asked.

"It will delete everything that is on here"

The room went silent as Ryan, Walter and Eric exchanged looks.

"Something's not adding up here" Calleigh said breaking the silent between the guys.

"How do you mean Calleigh?" Horatio asked taking a step closer to the blonde.

"Natalia was the only one to use the Hummer, expect for Eric when he towed it back here. When the Hummer was checked out it had 125,000 miles on it. Its 25 miles from here to funeral home, meaning that there should 125,050 miles on here. But the log says that says that the Hummer has 125,100 miles on it." Calleigh explained.

"There are 50 extra miles there." Eric said deep in thought.

"Maybe she ran a quick errand before going to crime scene." Dave said adding his two cents.

"No, ever since the hole Stetler scandal came out about him stealing cars, the county wired GPS into all the police cars. People started getting in trouble about running errands on the job." Ryan said who was now standing by Calleigh looking at the folder.

"Well if they keep track of the Hummer's movements let's just ask for log," Dave said looking around at everyone.

Horatio got his phone and called downstairs and asked for the GPS file on Hummer #35, with in minutes the file was being downloaded to Dave's screen.

"Okay let's see what we have here. At 6:50 a.m she went from the lab to crime scene, arriving there at 7:10 a.m. The Hummer does move till 10:45 a.m." Dave said looking at the screen.

"Where did it go?" Eric said leaning in closer.

"Let's see it went to a Nathan's custom auto car shop on Hialeah Hia Gardens Blvd. It was there for about 20 minutes till it drove back to the scene, then back here." Dave added.

"Okay, here is what we are going to do. Walter you stay here with Dave and see what you guys can get off that Dongle, Calleigh and Eric process Natalia's Hummer and Mr. Wolfe, you and I are going to Nathan's custom auto car shop." Horatio said, but just before he was going to put on his sunglasses a firm "No!" was shouted.

Everyone looked over to the petite blonde as she stood there, "I'm going with you Horatio." She said.

Horatio gave a slight nod indicting that Ryan and Calleigh would trade places. Once again the CSI's all went their separate ways.
