AN: My first CSI fanfic… I apologize in advance for any grammar and spelling…

Chapter One.

"Calleigh?" Eric reached out a hesitant hand to her only to have her push it away and back away from him.

"Calleigh please look at me."

"No! Just leave me… please, I can't… I can't do this anymore. Please…" she pleaded moving further from his grasp.

"Please" she whispered, his heart broke when he saw the tears running down her face.

"Let me help you." He begged reaching for her once more only to have her push his hand away again.

"What do we have?" Calleigh asked as she and Eric made their way to Horatio.

Before he could respond Alexx cut in. "Caucasian female, early thirties looks to be beaten to death but I won't know for sure until I get the body to the lab." She told them removing her gloves.

"I guess we better get started." Calleigh announced making her way to the body.

Eric turned to the surrounding area to see if he could find any tracks left by the attacker.

"Found blood under her finger nails." Ryan said as Calleigh snapped a couple pictures of the victim's body.

"Hopefully it belongs to our killer." She smiled zooming her lens in on the bruises that covered the woman's body.

"I found some tire tracks." Eric told Horatio while snapping pictures. "Good work Eric, keep looking" Horatio adjusted his glasses and walked over to the body.

"Find anything?" He asked his two CSI's.

"Ryan found some blood under the finger nails, some finger prints, we'll know more once Alexx can examine her." She lowered her camera taking all the pictures needed from the scene.

"I'll be glad when this shift is over" Ryan said running the blood sample they had retrieved underneath the victim's nails.

"You and me both man… no matter how many crime scenes I process it still amazes me the extend someone will go to take a live, you think you've seen it all."

"Eric? Did you get anything off of the victim's prints?" Horatio asked stepping into the lab.

As if on cue the machine beeped giving them a match.

"Sandra Mitchell, reported missing a week ago." Eric told him and not seconds later Horatio's phone went off.

He answered the phone placing it to his ear. "Okay Alexx I will be there in a minute."

He snapped his phone shut and made his way to the door. "Alright Eric, find out who reported her missing and let me know if you get a match on any of the prints found on the body."

Ryan looked to his screen as the results for the blood sample came in. "Eric, the blood under the victim's nails belongs to her."

"Are you sure? Why would she scratch at herself?" He asked as he looked at the screen.

"What do you have for me Alexx?" Horatio walked in to find Calleigh already there.

Alexx moved towards the neck and began turning the head when Horatio's phone rang.

"Thanks Ryan" He said hanging up and redirected his attention back to Alexx.

"Ryan says the blood under the nails belongs to the victim."

"Well that explains what I am about to show you." She told him pointing to the marks at the back of the victims head.

"What would make her claw at her own skin?" Calleigh asked stepping closer to the body.

"I asked her the same exact thing. So I looked a little deeper and that's when I found this." She told them holding up a little device.

"What is that?"

"I don't know Horatio, I am only here to tell you how she died." She placed the little electronic piece into an evidence bag and handed it to Calleigh. With it she walked out of the lab.

"Hey guys" she smiled as she found Ryan hunched over looking at the prints while Eric was trying to match the tire marks he had found.

"Hey Calleigh, what've you got?" Eric asked looking up.

"Well Alexx found this in the victims head." She opened the small evidence bag and took out the little electronic device.

"What is it?" Eric asked taking the small piece and looking at it closely.

"I have no idea, that's why I'm here." She took the piece from him and placed it under the magnifying glass to get a better look.

"Hey" Natalia said joining the team in the lab. "Horatio had me look up similar MO's after locating the device and guess what?"

"It's not the first time?" Ryan asked already knowing the answer.

"Nope, two other females within the last 4 weeks. Erica Carter from Virginia and Crystal Johnson from North Carolina, both were reported missing and then found one week later dead, both had their own blood under their nails, both Caucasian and in their early thirties."

"Crystal Johnson" Calleigh repeated.

"You know that name Cal?" Eric asked breaking her concentration.

"It sounds so familiar I've heard it somewhere." She paused trying to remember where she'd heard it.

"We'll need the evidence collected from those crime scenes." She told Natalia as she turned to the magnifying glass once again.

"Already on its way." Horatio smiled walking into the lab. "Anything on the device?"

"Well I found the serial number, with any luck we'll find the company that carries it and hopefully they'll have the name of the buyer."

"Good work, Alexx said the cause of death was repeated blows, the one to kill her was a kick to the abdomen, victims rib broke, puncturing her lung causing internal bleeding."

They'd all seen so many ways people had been killed before but to go in such a painful way made the team cringe.

"Horatio the tire tracks we found at the scene belong to an SUV, Trail Blazer maybe Explorer."

"Good work Eric. Anything from the prints found on the body?"

"All of them belonged to Sandra Mitchell except for two. I've ran them through CODIS, couldn't get a match." Ryan replied.

"I talked with the investigators that were on the other two cases and they told me the only prints they found were those of the victims, so we may have the killers print." Natalia cut in as the chance of catching the killer grew.

"That is definitely a plus Ms. Boa Vista. Alright, keep looking Ryan. Calleigh, what about the device?"

"I found the company that sells it, they're called Electronic Solutions, they manufacture electronic devices for automatic blinds, doors, remote controls for your TV, radio, you name it. They reported a batch of them stolen 6 weeks ago."

"Giving our killer a week before the first murder." Horatio remarked as he played with the tip of his glasses.

AN: Well that's it for Chapter one…let me know if I should continue… R/R please.
