Author's Note:

So this is my first Criminal Minds fanfic and my first ever fanfic! Tell me what you think. If there's any mistake please tell me (I'm not so good at writing. -_-).

OC characters: (Sorry if it gives away story)

Charlotte Whitman (Wong): Daughter of Sarah and Jason Wong. Parents/family were murdered. She is fifteen years old and is a junior in high school. (She's suppose to a freshman but in elementary school she skipped 3rd and 4th grade.) Charlotte won first place in the Karate Nationals for the Ninth time. Her first win was at the age of six. And Charlotte also works for the BAU. Kristina and David are her adopted parents.

Sarah Wong: Charlotte's birth mom.

Jason Wong: Charlotte's birth dad.

Kristina Whitman: Sarah's best friend. Adopted Charlotte after her parents/family were killed. (Charlotte's adopted mom) Mother of Lucas.

David Whitman: Jason's best friend. Adopted Charlotte after her parents/family were killed. (Charlotte's adopted dad) Father of Lucas.

Lucas Whitman: Charlotte's best friend. Charlotte's adopted brother.

How does the BAU get involve: (Sorry If it gives away too much stuff.)

Charlotte is a highly skilled fifteen year old girl. When she was fourteen and won her ninth first place trophy for the karate national, she got a call from the BAU. The BAU hired Charlotte as a secret agent. Charlotte has perfect shot when firing a gun and can beat Dr. Reid at a game of chess. The BAU gets involve in this case because Charlotte's whole family has been killed and the next victim is the BAU team. The BAU know that the unsub is killing everyone that is important to Charlotte but the unsub does not kill the Whitman family (Who is way more important to Charlotte than the BAU team) and it leaves a huge clue on who the unsub may be.

Sorry if this author note is way TOO long. I had to put in everything I thought was important(which is a lot!) Please read and review. I love getting reviews! It helps me! But in the reviews don't be too mean.

-Chapter One-

A Strange Note

Charlotte stares at the dirty bus window, noticing that her stop was next. She couldn't wait to get home because today was her birthday and her parents are going to take her out for dinner. When the bus finally stops in front of her home, Charlotte gets up from her seat and walks off the bus. Walking to the front door, she notices that the door was wide open. Her heart beats faster than ever.

"Mom? Dad? Is anybody home?" Charlotte yells but didn't get a answer. Walking into her parent's bedroom, she saw her parents dead and covered in blood. "Oh no! how could this have happened? I got to called the team."

Charlotte reaches into her pocket to look for her cell phone but it wasn't there. "Where did I put my cell?"
Charlotte walks to the living room to check if her cell phone was in her backpack. As she open her backpack, she found her phone and heard someone knock on the front door. "Who is it?"

"Charlotte, open the door. It's Kristina and David. We tried to call your parents but we got cut off," Kristina said while Charlotte opens the door.

"What's wrong?" David asks, seeing the tears in Charlotte's eyes.

"Just follow me," Charlotte said leading them to her parent's bedroom.

Opening her parent's bedroom door, Charlotte let out more tears. Kristina frozen from what she just saw and David shock at what he saw. Charlotte walks around her parents bedroom and finds a note on top of the wooden dresser. The note reads:

I'm Sorry I had to do this.

I was force to.

Please forgive me!

I REALLY don't mean for this to happen.

Sorry Charlotte.

I'm truly sorry!

YOU GOT TO HELP ME!

I REALLY DON'T WANT THIS TO HAPPEN!

BUT I HAVE TO.

I'M FORCE TO!

Once again...

I'm truly sorry Charlotte.

'The note seem a little strange. Why would the killer leave a not saying sorry? How was the killer force to do this? I gotta call the team.' Charlotte thought. Charlotte notices that there are teardrops on the note but it's not hers.

"Whoever did this, really didn't want to do this. But who can it be? Who force him to do this? It it even a him? Can it be a her? So confused. Too mad. Too sad. Why would anybody do this?" Charlotte said as more tears roll down her face.

"What? How could this have happen? Your parents are loving people. They were always so nice to everybody, even when people were rude to them. How could anybody do this? Charlotte call the BAU now," Kristina said sadly, hugging Charlotte. "David, go call the police."

Charlotte dial Aaron Hotchner number.

"Hotchner."

"Hi Hotch. It's Charlotte. Come to my house now! I need help!"

"What? Slow down. Tell me exactly what happened."

"My parents were murdered. The person who killed my parents left a note. A very strange note."

"What did the note say exactly?"

"Um... I'm Sorry I had to do this. I was force to. Please forgive me! I REALLY don't mean for this to happen. Sorry Charlotte. I'm truly sorry! YOU GOT TO HELP ME! I REALLY DON'T WANT THIS TO HAPPEN! BUT I HAVE TO. I'M FORCE TO! Once again... I'm truly sorry Charlotte. How does the killer know my name?"

"I don't know exactly. We're on our way." Hotch said hanging up the phone.

-Quantico Headquarters-

Hotch storms out of his office and towards his teammates. "We got to get to D.C. now!"

"Why? Shouldn't we go over the case before we get to D.C.?" Dr. Spencer Reid asked.

"We don't need to go over the case. Charlotte's parents were just murdered. Now come on! Morgan, grab the car keys," Hotch said without stopping to wait for the rest of his team.

The team didn't asked anymore questions, instead they grab their guns and ID badges and head to the elevator where Hotch was waiting for them.

-Washington, D.C., Charlotte's house--

The police put crime scene tapes around the house. The BAU team got to the house.

"Sorry, but you guys can't come in," The policemen said.

The team got out there badges and said, "FBI, we got a agent in there."

Without waiting for an answer, they just walked into the house. Looking around for evidence. Emily Prentiss and Spencer Reid walked into the parent's bedroom and finds Charlotte there.

"Guys, in here!" Prentiss shout to her teammates.

"Charlotte. You okay?" Reid asked.

"Yeah. But there's something I need you to look at. It's a note the killer left. It's just.. Well... Really strange," Charlotte said, handing Reid the note.

"I'm Sorry I had to do this. I was force to. Please forgive me! I really don't mean for this to happen. Sorry Charlotte. I'm truly sorry! You got to help me! I really don't want this to happen! But I have to. I'm force to! Once again... I'm truly sorry Charlotte. Who ever killed your parents, really didn't want to. But why? And who is forcing the unsub to kill your parents?" Reid said.

"Reid, do you see those teardrop stains on the note? It was there when I got it. I believe that the person who killed my parents actually knows me and my family really well. But the person is being force by someone. But who can it be? My family has always been friendly to everybody, even when people won't friendly to us. This is just too confusing," Charlotte said as she starts to cry again.

"Charlotte. You said there was a note. Can I see it?" Hotch asked when he entered the bedroom.

Reid hands the note to Hotch. "Hotch, the note is strange. It's like.. Well.. The unsub probably doesn't want to kill anyone but is force to."

"Yeah. Look at the handwriting. It's messy. The unsub was in a hurry. In a hurry for what?" Hotch said to Reid.

JJ walks into the bedroom towards Charlotte. "Happy Birthday, Charlotte! How's it going?"

"Thanks JJ! Well... I had way better birthdays than this one."

"You okay?"

"Yeah. I just can't believe it. But for some reason I'm very sad but can't show it. Why?"

"Probably, you been hanging out with the BAU too often now," JJ said smiling at Charlotte.

"Haha. Thanks." Charlotte was crying really hard now. JJ wraps her arm around Charlotte's shoulder to comfort her.

"It's going to be just fine, Charlotte. We'll find the killer."

"Thanks JJ. You always know how to make people feel better."

"It's a gift!" JJ said smiling.

Charlotte, JJ, Emily, Rossi, and Morgan walks over to Reid and Hotch.

"So, how's it going?" They all said at the same time which was funny but weird and scary.

"We believe that the unsub it someone you know," Reid said looking directly at Charlotte.

"But who? I know a lot of people. I been traveling to a lot of places for my snowboard, skateboard, and karate competitions. It can be anyone."

"Have you met anybody who dislike you or is jealous of you winning so many competitions?" Rossi asked.

"When your in a competition everyone is jealous of you. It's just the way life goes. It can be anybody like I said."

"Charlotte!" Kristina yelled walking towards Charlotte.

"Yeah?"

"Well... David and I were talking things over. Since you have nowhere to go, we would like to adopt you."

"Whaaat? Really? That would be awesome. Plus you guys known me since I was born and are my parent's best friends, but what about my grandparents and my only aunt?"

"Yeah. We know. We called your aunt. She said it's okay. Your grandparents said it was fine to. So what do you say?"

"I would love that! Are you guys legally adopting me?" Charlotte asked being curious.

"No duh, silly!"

"So you become my mom? And David becomes my dad? Lucas becomes my big brother?"

"Yeah. We'll take you to the family courthouse tomorrow to make it official."

"Would I change my last name from Wong to Whitman?"

"Only is you want to."

"Sure. I'll change it, so it seems like I'm really apart of your family," Charlotte said smiling.

"Hahaha. Tomorrow when we go to the courthouse, we'll also change your last name," Kristina said with a smirk.

Charlotte turns back around facing the BAU team. "So... Is this a new case or something? Can I be a part of it? I haven't done a case since school started."

"I guess we have a new case then. But you can't be in this case, you have school," JJ said.

"No. It's summer break. We're out of school."

"Charlotte, it's January. Someone is lying," Emily said staring into Charlotte's eyes with a small smile.

"Fine. Wait! I can get excuse from school. I'm already two years ahead of school. I can ask Kristina if I can. And then one of you guys can write me a note to be out of school for awhile. PLEASE! This case involves my parents! I have to help. You guys know it!"

"Okay. Fine but only if Kristina says yes. Kristina! Can you come over here?" Hotch said.

"Sure," Kristina answered walking to the group.

"So, Charlotte wants to know if you'll let her be off a school for awhile to work on this case. So can she? We just need your permission," Emily explained.

"Yeah. That would be okay. Plus she's already two years ahead."

"Yes! I can help!" Charlotte said dancing around.

Hope you guys like it! I think I made a lot of mistakes but forgive me for that. Please review! Tell me what you think and what you think of my OC Charlotte. ^.^
