Disclaimer: I own nothing, not Criminal Minds (CBS), not Rizzoli and Isles (TNT) I'm just taking them out to play for a little while.

A/N: Uhmm wow! The number of story alerts and reviews lead me to believe that some of you have wanted this kind of crossover. I hope to not disappoint. (My longest story so far is 30 chapters for R and I –Fear and All Its Beauty) This is the first time I am writing for Criminal Minds-(I'm a bit terrified)

Also, just for clarifications sake, some folks have asked about when in the timeline of the CM and R and I worlds this is occurring, here goes: This is post S1 season finale of R and I, so yes, Jane shot herself to save Frankie and Maura. As to CM, this is post 'Lauren', Ian Doyle and is set after Emily's return and congressional hearings. With one show on TNT and the other on CBS, the seasons don't run in the same time frame so…(literary license has been exercised) Enjoy!

Walking into the conference room, Jane looked around at the set up. Frost had brought in the portable smart board and had hooked them up with a computer. On the screen was the weirdest person Jane had ever seen. She came across as an explosion of color and energy.

Frost was sitting animatedly at the keyboard, nodding and responding to the woman on the screen, headphones in his ears.

"Good lord, Frost made a friend"

Walking over, "Detective Rizzoli, and Dr Isles I presume?" Hotch knew who she was but wanted the woman to feel comfortable.

Extending her hand, "Yes, yes I am Agent…"

"SSA Agent Hotchner ma'am, and I believe you know Agent Rossi?" Looking at the other man, Maura smiled widely, "I certainly do, how've been David?"

With a warm smile, Rossi gave her a brief hug; aware of the protective stance the Detective had taken next to her. "Good Maura…and you, how have you been?"

Waving her hand at the files and pictures of the victims on the bulletin board, "busy"

Hotch sensed an ally in this woman and was happy for it. Detective Rizzoli was still an enigma to him and he couldn't tell yet whether she would be a help or hindrance to this investigation.

"Well then, can I get everyone's attention please, I'd like to have a briefing in about five minutes. Detective Frost if you could insure we have audio with Ms. Garcia…"

"Already done."

Smiling Hotch nodded, "Dr Isles, Detective will you join me?" gesturing to the small office outside the conference room, Jane let Maura lead the way. "Prentiss, JJ, office please.

Jane sat down rubbing her hands, it was a nervous habit she hated since it drew attention to her scarred hands but she hadn't been able to break it. Maura patted her knee reassuringly as they waited for Agent Hotchner to sit down. Agents Prentiss and Jareau were already seated.

"Detective," he started "I know that you don't want us here, but we are here and if we are going to be effective at all, we need your help. This is a joint venture and we are here by invitation only, so, that said. We won't step on your toes but we want you to readily utilize the resources that your Chief of Police has given you." Looking directly into her eyes, "We're here to help you"

Jane thought about his commentary and the fact that of all the agents he could have brought in, he had brought in the two women assigned to his team. She knew he was making a point and she had to admit that part of her irritation was the introduction of more testosterone into her investigation. She could feel Maura looking at her as well as the two female agents.

Sighing, "I get it okay, I'm not completely happy about it but" and with a wry grin, "who am I to look a gift horse in the mouth" the sincerity in her voice surprised them all. Emily and JJ exchanged an appreciative look and at a nod from Hotch left the three alone.

Sensing the tension, Maura broke the silence, "Agent Hotchner, I'm sure we're all going to be able to work together to make sure we can apprehend this individual. I think we'll all be able to compliment each other." That said, she stood, "shall we go, I have some new information based on the autopsy of the most recent victim that I would like to discuss with everyone"

Maura looked quickly at Jane and tried to hide the hurt she felt from Jane's glare. Walking out ahead of her, it was obvious that Jane was angry with her for not giving her the information first. Sighing she followed Jane out, unhappy about the discussion they were sure to have.

As soon as everyone was situated, Hotch gave the floor to Maura.

Trying not to look at Jane, "Well, the first four victims, were beaten severely around the abdominal and pelvic area before ultimately being strangled to death. Our second victim had been beaten so severely that it was difficult to ascertain what caused her death asphyxiation or internal bleeding. Needless to say the force used by this individual is…extensive. Yes, Dr Reid?"

"Is there any evidence of an object being used in the beings? Beatings that severe every two days have to be damaging to our Unsub."

Maura thought about how best to answer, she had her suspicions, but she did not like to guess and unlike Jane she refused to rely on her 'gut', instead. "There is no specific evidence of an object being used however, the impact surface area is rather large and…" seeing the confusion on their faces, she quickly looked around, "Agent Morgan, could you extend your dominant hand please"

Wondering where she was going with this, he obliged. Holding his hand, Maura explained "Now Agent Morgan,"

"Derek" he smiled, she had soft hands.

"Derek has possibly the largest hands in this room" The snickers and muttered comments were lost on Maura so she continued. "Derek if you could close your hand as if you were going to punch somebody." Doing so, she again held out his hand, "if you measure the size of his fist relative to the size of an impact made by him, you would find it smaller than the actual fist because when you actually throw a punch, your hand naturally angles so there is never a consistent size, just an average." Expectantly, she looked at Reid,

"Gloves, the person is wearing some type of glove, boxing, mma." Surprised, Maura looked at the woman who had answered. Emily Prentiss was almost as book smart as Reid and she was certainly more street smart. She knew exactly where Dr Isles was headed but she didn't want to interrupt especially seeing how uncomfortable Morgan was whenever she touched his hand.

Smiling at her surprised look, "is that what you were getting at?" she said kindly, earning a glare from JJ. Prentiss knew she was flirting but it seemed like such an easy to do with Dr Isles she couldn't help herself.

"Yes, exactly!" happy that someone understood, she continued, "well, besides the likeliness of the gloves, there is the question also of the amount of force needed to cause that much damage. You see…"

"Weighted gloves! Morgan you use those don't you? They're used to increase speed but what if they are being used as gloves, would that explain the confusing nature of the contusions?" Reid's boyish smile earned him one in return.

"Yes Dr. Reid, a weighted glove could cause that damage. I cannot say for certain that it did. I was simply offering a hypothesis based on the evidence I had up to the fourth victim."

"Excuse me Doc," Korsak looked over at Jane waiting for her to say something, anything but she was just sitting there glaring at Maura. "Good grief Jane, really?"

"Why up to the fourth victim? Wasn't she beaten and strangled as well?" He knew she had been working on the autopsy all morning.

"Yes Detective, she was, but our fifth victim appears to have also been sexually assaulted, prior to her death."

"But why?

"Why not?

"Something must have precipitated?

"Its very unusual?"

Maura was taken aback by the at the amount of discussion that one statement had, she was thinking in terms of evidence they were thinking profile

"The offender left no DNA and the only trace evidence I found were some fibers that I was examining before this meeting." Maura queued up the pictures of all five victims. There were two pictures, one headshot and one post mortem displaying the injuries. "The nature of the injuries was almost identical, almost methodical. The first and second blows tend to do the most initial damage to the victim. The subsequent repeated blows…"

Hotch was impressed, this was some of the best information they'd ever gotten to begin to formulate a profile. And figure out why the sudden sexual assault.

"Thoughts?" Hotch posed the question primarily to the members of his team but wanted input from everyone, and thus far, he looked over, Detective Rizzoli had said nothing.

"White Male, athletic, or used to be…"

"Same age range as victims, approx 25-35 years of age" with the pause in ideas,

"Alright people we have five victims from diverse backgrounds, Garcia, we need everything Boston PD has on them and what you can dig up, we need to see how they tie together, also…" Hotch was surprised by the sudden interruption.

"Look at them,"

Jane's voice was cold, the raspiness of her voice more noticeable because of her agitation. "I'm sorry detective look at who?" Rossi said quietly, he had noticed the detective's increasing agitation and had worried she would cause a scene.

"Look at the victims, what do you see?" frustrated Jane looked for her people, ignoring Maura, "Frost, pull up the pictures we have that the families provided." She waited until they were up, "Agent Rossi, what do you see?" the seriousness of her voice made him look without question.

Looking at the smiling faces in the pictures Rossi didn't see what she was pointing to, looking back at her Jane just raised an eyebrow at him and nodded toward Prentiss.

"Son of a Bitch!"

Catching everyone's attention, he looked at Jane again and opened his mouth to apologize, when she turned and walked out.

"What the hell was that about Dave?"

"We've got it wrong Hotch, look?"

They all turned to look even Maura, "Oh my goodness,"

JJ looked at Emily in shock, "what?" JJ's look surprised her.

Shaking her head, "you could all be sisters, different ethnically, sure but look at them, Detective Rizzoli too."

Maura moved to go after her but was waved back by Emily.

Emily looked at the pictures and back at the eyes on her, "crap…I'll go get her"

Leaving them to try and formulate a new profile, Prentiss found Jane at the coffee machine pouring herself a cup.

"Want one?"

Never one to say no to coffee, "Sure, thanks. You okay?"

"Sure, aren't you, I just love resembling the victim of a serial killer at least once a year, didn't you know" Jane knew she wasn't being fair or nice to the other woman but contrary to what Maura thought, nice doesn't always work "how do you feel, you resemble them too."

"I know and it unnerves me but I'm still going to do my job and part of that is helping you do yours." Extending her hand she realized if no else on her team did she was going to reach out to the detective.

Seeing the outstretched hand, Jane hesitated but she needed an ally and if this woman was willing, then so be it as long as she stayed away from Maura. Shaking her hand she laughed out loud.

"What's so funny?"

"This, didn't they brief you? I'm like a friggin serial killer magnet, I'm guessing things are going to get pretty interesting around here soon, sure you're up to it." Emily heard the challenge in her voice and accepted.

"I am if you are"

So I hope you all are still enjoying this story, let me know how you feel and what you think. The interactions here are way more difficult than working a single show, but I am trying to stay as true to the characters as I can. Yes there will be much more Garcia and our favorite ladies will be interacting much more as well. So please I need feedback, review, review, review. Have at it, go to town (you know what I mean)
