New York, New York – 11:42 pm

"What've we got?" Olivia asked, ducking under the crime scene tape beside Elliot. It was elven o'clock in the evening and they were investigating yet another rape and murder case committed by the killer the press had dubbed "The Violator" due to his mutilation done to the bodies. To make matters worse, he was recording video diaries and posting them on the internet with his face covered up, his voice tuned out, and his every little detail about the killings revealed.

Their medical examiner Warner gestured to the body of a girl who couldn't have been older than eighteen, her face slashed up and her body covered in deep lacerations.

"Our perp struck again," she said bitterly, shaking her head from her position of kneeling down next the body. "This guy is getting worse."

Olivia sighed as she looked at the poor girl on the ground. The bastard who'd done this to her deserved to rot in a cell for the rest of eternity. And he would if she got her hands on him. "Do we have a name on our victim?"

"One of the ladies over there identified her as one of the regulars on this block," Fin reported. "Her street name is Kitty Duvall…real name Sally Hawkins. She's seventeen years old. She was apparently going to college at Hudson, doing this on the side to pay the tuition is what her girlfriends over there tell me."

"All that was found on her person was a purse, usual things for a prostitute: lipstick, wad of cash, et cetera," one of the other officers added.

From beside her, Elliot's cell phone rang and he answered it. Olivia took the opportunity to survey the scene more. Her job was rough, she saw things no one else saw or even fathomed seeing. The capacity some people went to show their blatant disrespect for human life never ceased to amaze her. And this rapist, this killer, was one of the worst she'd seen in a long time.

"Yeah," her partner said into the phone before hanging up. Turning to her, he said, "Captain's on his way. He said he's got an announcement for us."

"I can only imagine what he's got to tell us," she huffed.

Twenty minutes later when Cragen arrived at the scene, Olivia, Elliot, and Fin gathered around to hear his announcement. "What's up, Captain?" Fin asked impatiently.

Cragen took a deep breath. "I know how you all feel about the Feds," he began hesitantly, "but there's not much more we can do now. We're up to our sixth victim and we have no idea what to do to catch this guy."

"So you're calling in the Feds?" Elliot asked incredulously. They all hated working with the Feds, particularly Elliot. "Captain, we can figure this guy out."

Cragen shook his head. "No," he said bluntly. "We can't risk another victim. So I've called in the FBI's Behavioral Analysis Unit to assist. These people are top of the line, best at what they do. Maybe they can help us figure out what to do to catch this bastard. I'm sure they can help." He paused to study them all with a strict gaze. "I trust you can all be civil with them. They're here at my invitation."

With much grumbling, the detectives of the Special Victims Unit agreed to their Captain's decision and set about finishing the crime scene.

"What've we caught?" Alex Blake asked as she sat down with Derek Morgan by her side in the Round Table room.

At the head of the room, Penelope Garcia clicked the remote to show crime scene photos sent to her by the NYPD's Special Victim's Unit. "Six women have been killed viciously – faces slashed, bodies mutilated, and raped repeatedly – and their murders have been vlogged about on the web." Her face very clearly showed her disgust, her skin ashen and eyes dreading the talk.

"These are vicious killings, obvious overkill done to the bodies," Rossi said pointedly.

"Why the hell did it take them to six victims to call us in?" Morgan demanded. "They should've called us in after two."

"Well, they haven't," Hotch said bluntly. "We've got to get in there and catch this unsub before he kills again." He turned to Garcia. "Garcia, you're coming with us. If this man is using the web to talk about his crime, we'll need you along."

She nodded. "Yes sir," she said.

Hotch rose. "Right then. Wheels up in thirty."

"Agents, I'm Captain Cragen," Cragen said, extending his hand to Hotch.

"Captain, it's good to meet you," Hotch said. "I'm Agent Hotchner…these are Agents Rossi, Morgan, Blake, and Jareau. This is Dr. Reid and our technical analyst Penelope Garcia."

Cragen nodded. "I suppose it's only fair to introduce my people to you too," he said. Motioning to his detectives to join him, he said, "Here we have Detectives Stabler, Benson, Tutuola, and Munch. They'll be who you're working with on the case." He shot his detectives a hard look, clearly telling them to be polite.

Detective Benson nodded to them. "Pleasure," she said.

She took the opportunity to observe the Agents. The two older of them were very clearly the leaders, while the youngest of the bunch was on edge. The long haired brunette was stood tall next to him and exuded intelligence. Behind them was the tall, extremely handsome African American man who was watching protectively over the red-headed technical analyst. In his gaze there was also deep love and affection. Essentially, the man was smitten.

But it was the blonde-haired agent that caught her eye. She was the most beautiful woman Olivia had seen. But before she could look at her more closely, she snapped out of the daze and focused on the case and what the head of the team was telling them.

"Blake and Reid, Captain Cragen wants you to go to the crime lab with Detective Stabler," Hotch said. "Rossi and I will speak to the families with the Captain, JJ and Morgan, you're with Detective Benson. Garcia will stay here with Detectives Munch and Tutuola."

"Let's get started then," Cragen said.
