The apartment was covered in blood, well the floor and the one wall was. The body had been removed shortly before the two agents got there.

"What do you thinks going on with Aaron?" Derek questioned Reid as they pulled into the shady apartment building's parking lot.

"The mother of the boy came into the BAU to see Aaron 4 days ago." Derek gave him a side glance as he parked the car and turned it off.

"What? Why?" Both men opened their doors and walked out towards the police that were still on the scene.

"JJ said she just asked to see Aaron, and after that he walked her to her car. She had been very nervous on the elevator ride up."

"You think it has something to do with this?" Derek gestured to the scene in front of them.

"I think Aaron would have mentioned something if it had to do with this." but Derek couldn't shake the uneasy feeling in his stomach. The cops seemed to be wrapping up when they made it to the apartment.

"Forensics' already been through here so you can do whatever." One of to cops informed them

"Did they find the murder weapon?" Reid asked, moving to look around, stopping at the wall with the writing on it.

"Nope, this place was completely spotless, no prints, in and out." Derek nodded, moving to open the closet next to the front door. Behind a few boxes four bags sat neatly against the wall. They were all a plain black color and each the same size. He opened the one closest to him, inside were a few men shirts and jeans, at the bottom a prepaid disposable phone and at least 500 dollars in cash. The one after that was similar, except it was filled with women's clothes, the one after that only held children clothes and a photo album. The last one only had toys inside.

"Reid, they were ready to run, they've got bags packed and everything." He closed the bags before shutting the closet door.

"I only see cash, if they were on the run, their money must come from under the table jobs." Derek nodded.

"Then the mom should know who has the kid."

"She could have been threatened, talk and they kill the kid. Or it could be different people." Spencer added. "No forced entry."

"So the uncle let them in, but if they've been running from them, why would he let them in?" Nothing about this was making sense to Derek.

"Maybe the kid opened the door and the guy pulled out a gun and threatened to shoot him if Grayson did anything." Reid suggested.

"Eliza, I need you to answer a few questions." Aaron was doing his best to keep him voice calm and comforting, but after what he heard a few minuets ago he was finding it rather difficult. She seemed to have calmed down slightly since the last time he was in here, she was actually responding to him.

"What?" Her voice was shaky and her arms were wrapped around her middle in a protective manner.

"Do you know who has your son?"

"Not for sure." She shook here head. "I don- there's a lot of-" She began taking faster and was nearing the edge of hysteria.

"Calm down." She looked at him with wide eyes and took a deep breath before nodding.

"I need a pen and paper." Aaron placed the requested objects in her shaky hands and she began to write. She handed him the paper after a few minuets.

"There are a lot of names on this list."

"I don't have many friends." She wouldn't meet his eyes, she just stared at the red ring that was still around her nails.

"We'll find him." He carefully paced a hand on her shoulder, he was pleased when she didn't pull away from him. He really didn't want to ask the next question, not because he didn't want to know the answer, but because he didn't want to her to blow up at him again. "Is Aiden's father on this list?"

"No, no he's not."

"And you're sure he doesn't have anything to do with Aiden's disappearance?"

"Yes, he is no longer a threat to Aiden or myself." She said it with such confidence, like it was the one thing in her life she was sure of.

"How do you know?"

"I know because I'm the one that killed him."
