SSAs Aaron Hotchner, Jennifer Jareau, Emily Prentiss, Spencer Reid, and David Rossi were ready to be briefed on their latest case. They were waiting on SSA Derek Morgan and the tech analyst, Penelope Garcia.

"Where are Morgan and Garcia?" asked Hotch.

"I don't know," said Emily.

"Sorry we're late," said Garcia, as she comes in wearing a bright orange dress. "My car broke down so I called Derek."

"Not to mention it's flippin' 5AM. We just got back from a case last night at midnight," said Morgan.

"I know, and I'm sorry, but this couldn't wait. JJ?" said Hotch.

"Last year, 15 year old Alison DiLaurentis went missing while at a sleepover at her friend's barn. Almost five months ago, her body was found buried in her backyard. She died of suffocation, but suffered from blunt-force trauma to the head," explained JJ.

"Well, why are they calling us, if there aren't any other bodies?" asked Rossi.

"Alison and her four best friends were a tight knit group at Rosewood Day. The Rosewood PD has asked us to come in because they believe that one of, or all of these girls may be future victims."

"Do they have any suspects?" asked Reid.

"Toby Cavanaugh, a senior at the high school was accused, but later let off because of false evidence. Spencer Hastings, one of Alison's best friends, found a trophy belonging to her brother-in-law, Ian Thomas, with blood on it. The remaining three girls and she took it to the police department, believing it was the murder weapon, but it was rat's blood, not human's."

"Rat's blood?" asked Morgan.

"Rat's are the most common animals scientists use for research. They are small and easy to maintain," said Reid.

"So you're saying that our unsub is a scientist?" asked Morgan.

"Not necessarily. Not only are they easy to maintain, but they are easy to obtain. Our unsub could have easily have went to a pet store and bought one."

"Alright. The jet leaves in 20 minutes. We're going to Rosewood."

A/N: I know that these chapters are short, but they will get longer as the story progresses. So any constructive criticism would be awesome! And also, anything that Reid says, I will most likely make up. So just think of me as Wikipedia: I am fun to read but totally unreliable
