Title: Foster Murders

Author: Kitsune Rose420

Story type: Crossover: Four Brothers/Criminal Minds

Rating: K+ (just to be safe; it's for language)

Summary: There's a serial killer going around killing foster parents in the Detroit, Michigan area. The BAU team (excluding Garcia; she is still working the case, but is doing so out of their home office) is sent there and help comes in the form of Ms. Evelyn Mercer. (In my story, Bobby has already left-to do whatever it is Bobby does, Angel is in the army-though he might be coming home for a visit, not sure yet, and Jeramiah is married and living with Camille, and Jack is a senior in high school, still living with Evelyn. Since there aren't any safe hotels in the area and they have more than enough space, she invites them to stay with her and Jack. Unbeknowst to anyone, someone is planning a surprise visit to the Mercer household.

Side notes: I know that Derek is technically from Chicago, but for the sake of my story, pretend that he's from Detroit, and that he grew up with the Mercer boys, living only a few blocks away. This story is going to have Gideon, but no Rossi. I have nothing against him, but Gideon just fits better for my story idea. I, by the way, have no real knowledge of Star Trek, so I'm already sorry for the millions of mistakes I'm probably going to make with that alone.

**BAU, FBI Headquarters, Quantico, Virginia*****

It seemed, to the BAU unit, that it was going to be a quiet day at the office, catching up on paperwork and maybe a little sleep. Or, at least trying to sleep, which would be a lot easier for SSA Derek Morgan if he didn't have the resident genius telling him about the differences, for the third time in a row, between Star Trek and Star Wars.

" …the different atmosphers alone! I mean, while they both take place in outer space,", Spencer keeps rambling on, not realizing that his audience is currently hitting his head off his desk repeatedly, " Star Trek was primarily on a ship while the vast amount of Star Wars didn't happen anywhere near one, but-"

"Reid!" Morgan interputed, not being able to take it anymore, "If I hear one more comparison about them from you, kid, I'm going to make you wish you were on the U.S.S. Enterprise right now!"

In typical Reid fashion, Spencer looked thoughtfully into space and replied, "You think I don't wish that now, anyway? I think that would be incredibly fasinating! Just being able to learn about their technology alone-"

Morgan, seeing JJ walk into the bull pin, hands full of files, sees his opputunity and says, "Hey JJ, whatcha' got there?", walking over to her and taking half of the files she was holding, afraid she was going to drop them all. Spencer had followed behind him to help as well.

She looks up grimly and says, "Unfortantly, our newest case. Could you guys round up everyone for me and have them meet in the conference room in about ten minutes? I just have to put some old cases away quick."

"Sure", they both reply. Morgan and Reid then split up and told everyone. Ten minutes later, Reid, Morgan, Hotch, Gideon, Emily, even Garcia were all gathered, waiting for JJ in the conference room. A minute later, she came in and started passing out the folders on their new case.

"For the past year, there have been twenty reports of different murders in the Detroit, Michigan area."

"So?", Derek says, looking up after having glanced at the file, "I'm not trying to sound cold or anything, but I'm from Detroit. Twenty murders in a year is not an uncommon thing."

"It is when all the victims so far have been involved in the foster care system somehow." JJ states, turning on the screen, showing them the murder photos, "Fifteen so far have been foster parents and the other five have been social care workers." Turning from the screen to the team, she says, "If that's not weird enough, at every murder scene so far, the same note has been left."

"What did it say?" asked Spencer, ever the curious one.

JJ brought a photo of the typed letter up on the screen, "They are all finally going to get what they deserve." It's always the same note, same words, same font, same everything."

"Well," Gideon says, looking up from the case file, "What are we waiting for? Let's get going to Detroit."

Author's note: Okay, so I know that I have two other stories, and that I've left them in very awkward spots. Don't worry, though, to anyone who has nothing better to do than read the garbage that I write! My stories are NOT abandoned! The plot platypuses just wouldn't leave me alone untill I wrote this. (At first, it was just plot bunnies, untill they got eaten by the plot platypuses!)

Author's note: Reviews are very much appreciated, but not expected, considering that my writing is such crap that I'm amazed that anyone has liked anything that I've written so far. But, if anyone out there has nothing better to do, I would love to hear from someone, other than the voices in my head, what they think and if this story is worth continuing. If it is worth it, that damn platypus won't leave me alone just yet, meaning that I'll be updating a lot quicker than I have for my other stories.
