"Sir, we have a case" JJ said as she leaned into Hotch's office. Hotch nodded at her, finished what he was writing then followed her to the briefing where the rest of the team were waiting.

"Eight hours ago Lilly Mae Crawford went missing from a footpath on the outskirts of Mount Wilson in Las Vegas, Nevada" JJ said as Hotch settled into his chair. "The local police department have had search teams out for almost all of that time and they haven't found anything… it's like she just vanished" JJ added as she clicked through a few pictures on the screen of a little blonde hair, blued eyed Lilly Mae.

"Looks like you're going home, Reid" Morgan said jokingly and laughed.

"There's something else" JJ said quietly. The team looked up at her with confused faces and JJ let out a breath. "One of the cops thinks this is a serial abduction… He led a child abduction case identical to this but, because it was eleven years ago, the local PD aren't taking him seriously"

"An UnSub that can go over ten years without abducting a child? What are the chances of that?" Morgan asked.

"It's exceedingly unlikely" Reid answered.

"No percentage for me, huh?" He said with a little laugh and grin.

"14% of all known criminals haven't committed the same offence within ten years of the first offence, but that's including every crime, not just abductions or murder" He replied. Morgan raised an eyebrow then picked up his thin briefing folder.

"Wheels up in thirty" Hotch said, grabbed his briefing folder and left the room.

"So, pretty boy. What adventures will you be getting up to in the adult's playground?" Morgan asked playfully.

"I'd rather just get on with the case" Reid replied quietly, took his own briefing folder and walked back to his desk. Morgan raised an eyebrow at Emily but she just shrugged and went back to her desk with the folder.

"Everything alright, Spence?" JJ asked as she stopped by his desk.

"Yeah, why wouldn't it be?" He replied with a question as he dragged his eyes away from the case file, although there wasn't much in it.

"No reason, just…" She began but couldn't find the right words so gave up trying. "I'll see you on the jet" She finally said before smiling and walking away.

He hadn't meant to be so snappy with her and Morgan; he just always got stressed when there was a case in his hometown, Las Vegas. He grabbed his go bag from under his desk, slipped the file into his messenger bag then carried them out to his car, ready to drive to the jet.

"If we forget about the time difference between the two cases, there's no denying the similarities. Both girls were the same age, both were abducted off a track in the outskirts of Mount Wilson and both had blonde hair, blue eyes.

"If he really is this controlled and efficient then he's been at this a lot longer than eleven years" Morgan said thoughtfully.

"To build up this much skill he'd need plenty of years practice, who knows how many girls have gone missing" Reid said as his eyes glanced over the briefing document for the twelfth time since he'd been handed it.

"Hey, baby girl" Morgan said into his phone, he must have called Garcia without the team realising. Morgan laughed a little then said "I'm gonna put you on speaker, keep it clean" before he pushed a button and Garcia's voice was audible.

"Aw! You totally suck!" She said loudly down the phone but everyone knew she'd probably have the usual big grin on her face.

"Garcia, can you run a check on missing children in Nevada for us?" JJ asked, staring down at the phone.

"Of course I can, but I'm gonna need something a little more specific" She replied.

"Blonde hair, blue eyed girls between six and eight years old going missing in or around Mount Wilson, Las Vegas" Reid offered as he finally closed the briefing folder.

"Ok…" She said as she relayed the information into her computer. "Oh, I got something. Your girl Lilly Mae's on here but so are a bunch of other girls… all fitting the description perfectly" She said, her voice drifting off the slightest bit as she said the last sentence.

"Dates, baby girl?" Morgan asked.

"Oh, right, yeah… The most recent one was Lilly Mae… after her it was eleven years ago, less than a mile away from Lilly's abduction sight" She replied.

"You got anymore?" Morgan questioned.

"Oh, plenty sugar. After that was in 1990, then 1979, 1968 and finally 1957"

"The abduction dates are all eleven years apart" Reid stated.

"What were the ages of the girls exactly, Garcia?" Hotch asked.

"Uh… they were all seven when they disappeared" She replied.

"So, what? One girl turns eighteen and they abduct a new one?" JJ interjected.

"If the girls are still alive" Prentiss pointed out quietly.

"Well, this could take out a sexual component. Paedophiles have a very specific type and age plays a large part in that" Reid added.

"Or he could be keeping them until he loses interest then selling them on to other paedophiles" Morgan commented.

"Then why would he wait eleven years if he didn't have her for the entire time?" Reid asked.

"A trade off, one paedophile gives him a younger girl for the abducted girl once she gets too old for his preference" Morgan countered, the back and forth questioning adding an uncomfortable atmosphere to the jet's confined space that even Garcia felt back in her office.

There was a long pause before Morgan sighed and took his eyes of Reid and back to the phone. "Thanks for the help, baby girl… "I'll call you later" He said quietly, the jet was now almost completely silent.

"Oh you better" She said into the phone, her grin audible in her voice "PG out!" She called down the line before it went dead and Morgan hung up.

There was an awkward pause then Hotch cleared his throat and everyone looked to him. "There's divided opinions on the case so we'll keep both ideas in mind while building the profile, ok?" He said like a dad trying to make peace between his two sons.

"Yeah" Morgan replied quietly as Reid awkwardly nodded.

"Good. Reid, once we're set up I'd like you to place the abductions sites on a closer view of Mount Wilson so we can see just how close they are together. Morgan and Prentiss, I want you to try and make contact with the abducted girl's family from 2001 and find out as much as you can, after them work down. Rossi and I'll start from the bottom of the list and work up to get it done a bit quicker. JJ, the police haven't made an official statement about ther abduction yet so you can work on that with them. Everyone clear on what they need to do?" Hotch asked as he looked at each of his team members.

Reid nodded again, this time with his other team members. Morgan's eyes glanced over at him for a moment then back to Hotch.

Once Hotch had seen them all agree he opened up the briefing file and looked over it while adding "Good, because we're landing in 10"
