A/N: Ok so this is my first FF. Constructive criticism is welcome . Had this idea for a while, so now I'm getting it out of my head! Set sometime between Series 5 and 6 I think but I've only recently started watching the show so please allow for a little Poetic License!

May Day – Chapter One

Garcia looked out of the plane window. She was excited about being able to actually leave Quantico but was not looking forward to the things that may lie in store. The team were heading to Las Vegas. Five families had been murdered and the only connection between them was that they had all downloaded the same viral video the night before their murders. She was pulled from her thoughts at the sound of Hotch's voice.

"Ok so what do we know?" Hotch asked, looking around the plane.

"We know that the victims appear to have nothing in common other than the viral" JJ answered, looking at the case file in her hand.

"The Un-Sub is killing the children first," Reid said, not looking up from his file. "He's making the parents watch, tying them to their beds so they can't fight back,"

"How's he overpowering a whole family?" Morgan asked, looking at the team from his seat next to Garcia.

"He's drugging them while they're asleep," Reid answered. "Each victim had a track mark on their ankle suggesting he's injecting them with some kind of sedative."

"Tox-Screens all came back positive for Diazepam." Prentiss said, flicking through autopsy reports.

"Ok," Hotch said, "We know he's drugging them and we know the order he's killing in, but what we don't know is why or what connects them, apart from the download." He looked back down at his file.

"And that's where Garcia comes in." Rossi said, entering the conversation for the first time. "The viral is wiping the hard drives 12 hours after it's viewed. Nobody even knows what this video is about. The only people that see it are the victims themselves."

Garcia nodded. "If I can manage to access the hard drives we should be able to restore them and view it." She said.

"But if the drives wiped," JJ looked confused for a second. "Doesn't that mean everything's gone?"

"Yes," Garcia answered. "But in a lot of cases a digital burn is left within the hard drive itself. If you can access that you can usually restore most of the information the drive had on it."

"Wait," Prentiss said, shaking her head. "If this is a viral then how come he's only targeting people who view it in Vegas."

"He's emailing it to them" Reid answered. "The email address was set up.." He quickly looked through the file "Five years ago in the name of.. "He flicked through the folder again "Martin Harris," He raised his eyebrows "In an internet cafe in Birmingham, England."

"In England?" Prentiss asked, sounding surprised.

"Harris died four years ago in a motorbike accident" JJ said, placing a photo of the accident on the table between herself, Hotch, Rossi and Prentiss.

"Somebody hacked his account" Garcia continued. "But each time the Un-Sub emails someone he bounces off more IP addresses than a 70's kid on a Space hopper!"

Reid looked at her from his seat opposite. He looked like he was about to say something but changed his mind, instead turning to face the others. "So he is targeting them."

"Now we just need to find out why." Rossi said, staring at the photo of Harris.

"We'll be landing soon," Hotch said, looking at them each in turn. "Get some rest."

Reid had moved over the small sofa at the back of the plane. He was reading through the case file when Garcia came to sit next to him. "Hey" She said as she sat down.

Reid closed the file and smiled at her. "Hey," He replied, "You ok?"

She nodded. "I've never been to Vegas before." She said, smiling shyly.

"Really?" Reid asked. "Well when the case is over I can show you around a little if you'd like?"

Garcia clapped excitedly. "Ooh that'd be gooooood!" She replied. "You going to see your Mom while we're out here?" She asked.

Reid sat back and ran his hand through his hair. "I, erm..." He smiled awkwardly, "I haven't called her to tell her I'm coming." Garcia looked at him disapprovingly. "I know, I know," Reid defended himself before she could even say anything. "But if I tell her I'm coming and then don't make it she'll get upset. Plus last time I told her I was coming to see her she went off her meds so that she'd be sharper but that just ended badly." Reid shook his head. It was odd. He didn't really feel comfortable talking to anyone about his Mom except Garcia.

She smiled at him sweetly, but said nothing. She turned to face the others, then turned back to face Reid. "You want a coffee?" She asked, realising it was a stupid question. Of course Reid wanted a coffee.

OK so not much really happened, just setting the scene. Promise more will happen next chapter! If y'all could jot down a little review that'd be great. Hope I'm doing ok but like I said, first fic so please feel free to inform me of any obvious character faults. I don't really know how to write Rossi so he might not be in it too much, just FYI
