I know I haven't updated most of my stories (I will update as soon as inspiration hits). This is just a short story probably only going to be a few chapters long. Got the idea while watching season six of CSI Miami on DVD. Hope you like it & I only own the made-up characters, i.e. victims random cops etc.

Criminal Minds/CSI: MIAMI x-over.

Y.

Chapter 1: Innocence.

Miami, Florida.

Joshua Gordon smile to himself as he walked home from school. For once his parents would be proud of him. As he fumbled in his pockets for his house key he suddenly felt something tight around his neck. Everything went black as he tried to remove the noose around his throat.

When he came to, Joshua could feel that his hands and feet had been tied behind is back. He struggled to move and fell off the couch he had been placed on. He groaned and found he'd been gagged as well. Joshua heard a noise beside him and looked up to see where it had come from. His parents were tied up just like he was. His mother was crying. He noticed someone standing behind them. Someone he didn't recognise. The man walked towards his parents with something behind his back. Before Joshua could look away, the man used a butcher knife to slash both of his parents' throats from ear to ear. Joshua couldn't help but scream. A scream nobody ever heard. Before he could even open his mouth the man had grabbed a hand over it and ripped the blade through his throat from one ear to the other.

8 hours later...

"Frank, what have we got?" Detective Frank Tripp looked up.

"It's a bit of a mess in there, H. Parents and son all with their throats slashed from ear to ear. Nobody heard a thing. Neighbour called it in. They were supposed to be going over for dinner, when the neighbour couldn't raise anyone on the phone she sent her husband over to check it out, he rushed back and called it in." He replied.

"Do we know if anyone else lives in the house, Frank?"

"No, everyone that lives there is gunna be going home with Alexx. We're trying to get in contact with the mother's sister. So far we haven't had much luck."

"Keep trying, Frank." As Frank headed off to help the patrol cops, Lieutenant Horatio Caine walked inside.

"Alexx, what have we got?" Medical Examiner Alexx Woods looked up at the sound of Horatio's voice.

"It's a massacre Horatio. This boy is only 11 years old. Who would do something like this to an 11 yr old?"

"I don't know Alexx but I intend to find out."

(Cue MIAMI THEME)

While the rest of the team worked the scene, Horatio followed Alexx back to the morgue.

"This is the fourth family massacre in a month. Horatio, I hate to say it but I think we have ourselves a serial killer."

"I agree Alexx. Which means we need to work fast before he kills again."

"Everything is the same as the others. You know Horatio, you may some help with this one." Alexx looked at him through the plastic face covering she was wearing.

"Any ideas, Alexx?" She smiled

"Now, honey, I can't solve everything for you."

Horatio smiled as he walked out.

"H! Managed to catch the sister she's flying in from Chicago tonight. Caught the first available flight. Should I send someone to meet her?" Frank just managed to catch Horatio at the elevator.

"Good idea, Frank. Keep me posted." Frank nodded as the elevator doors shut.

Horatio walked into his office and shut the door. He sat down at his desk. The files of each of the families sat piled one on top of the other in front of him. The newest at the top. Horatio reached into a drawer and pulled out a card with a phone number and email address on it. He scanned the files into the computer and opened up his email and entered the address into a new message. He added the files, wrote a short message and clicked send. He picked up the phone and dialled the number.

"Agent Jareau? This is Lt. Horatio Caine from Miami Dade Police Department. I've just sent you an email containing the files of a case I currently have that is building way too fast. I would appreciate it if you and your team could take a look."

"I'll take a look and see what the team thinks. I'll call you back to let you know whether we're going to take the case." Came the answer.

"Thank you, ma'am." As he hung up, the door opened.

"H, we finally finished at the scene. It's the same as the others. Killer left nothing behind. All the blood belongs to the vics. Calleigh's checking everything for prints but so far there's none. Valera is running all of the blood just in case but we're not likely to find anything."

"Thank you Eric. Frank has someone meeting the sister at the airport. Talk to her see what she knows. Excuse me." Horatio added as the desk phone rang. Eric nodded and left.

"Agent Jareau, thank you for getting back to me so quickly."

"We're just heading to the jet hanger now we should be in Miami in a couple of hours. We'll go over the case on the plane."

"Thank you. I will meet you at the airport myself."

One hour previous

Washington, DC, Virginia.

Special Agent Jennifer Jareau was quietly sitting at her desk, absentmindedly staring at the photo of her, Will & their son Henry when her phone rang.

"Agent Jareau? This is Lt. Horatio Caine from Miami Dade Police Department. I've just sent you an email containing the files of a case I currently have that is building way too fast. I would appreciate it if you and your team could take a look."

"I'll take a look and see what the team thinks. I'll call you back to let you know whether we're going to take the case." JJ answered.

"Thank you, ma'am."

JJ printed out the case files and headed out of her office.

"Hotch? We've got a new case in Miami. Families being massacred in their homes."

Special Agent Aaron Hotchner looked up.

"Ok, I'll gather everyone in the conference room." JJ nodded and headed back to her office to make copies of the files for the rest of the team. When she walked into the conference room everyone was waiting.

"Miami. They've had four families massacred in their homes in a month. The latest family the Gordons were murdered sometime last night. Each of the families had a young son ages between 9 and 13. The only other similarities were the MO, slashing their throats from ear to ear, and the fact that the killer left nothing of himself behind. Lt Caine has asked if we could take a look and help him out before this guy strikes again."

"Wow, look at how he kills them. According to the autopsy reports he kills the parents first, probably makes the kid watch. Then, before the kid can react he kills the kid too. Question is what did these families do that pissed this guy off?" Special Agent Derek Morgan shook he head in disgust as he spoke.

"He obviously feels inadequate about something to cut them from ear to ear like that. He might be unable to perform sexually and he gets the thrill he needs by killing them so brutally." Doctor Spencer Reid suggested.

"Yeah, well whatever it is he's not likely to stop on his own. JJ you'd better call Lt Caine back and let him now we'll be there as soon as we can." Hotch said as he gathered his copy of the files. "Everyone ready in ten minutes wheels up in half an hour."

JJ walked back into her office and grabbed her overnight bag. Then she picked up the phone and dialled Lt Caine's number

"Agent Jareau, thank you for getting back to me so quickly."

"We're just heading to the jet hanger now we should be in Miami in a couple of hours. We'll go over the case on the plane."

"Thank you. I will meet you at the airport myself."
