Hotch and Morgan entered the interview room where Dunn was waiting. His head was resting on the table and he looked up when they came in.

"What am I still doing here?" he asked.

"We have some questions for you," Hotch replied, his face stoic.

"You can't keep me here. Emily's not pressing charges, I want to be with my daughter."

"Your paperwork has been misplaced," Hotch answered flatly. "While they're trying to sort that out we need you to answer some questions."

"Oh, my paperwork is lost is it? That's - " but Morgan cut him off.

"Hey," Morgan shouted. "Quit worrying about yourself. Your wife and kids were murdered and we need your help to catch whoever did this. Now quit bitching and tell us what we need to know."

Brady was quiet for a moment. "Okay," he replied.

"Eli Atocha," Hotch stated and Dunn stiffened. "Do you know him?"

Dunn paused, thinking before replying, "Yes, he was my cell mate in Osborn."

"Did he supply you with cocaine while you were in prison?" Hotch asked.

"No."

"He didn't?" Hotch verified.

"No, he didn't."

"Then how did he feel about you getting coke from someone else?" Morgan asked.

"What?" Brady asked.

"If you weren't getting drugs from Atocha, you were getting them from someone else," Morgan elaborated.

"No. I wasn't getting drugs from anyone in prison."

"Oh, well that's not true," Morgan replied.

Hotch continued, "You were an addict when you went into prison, you were an addict when you got out of prison. You were getting drugs while you were inside."

"And a guy like Atocha," Morgan said, picking up the thread, "he wouldn't like it if his cellie was getting coke from someone other than him."

"No, he wouldn't," Hotch agreed.

"He'd see it as a betrayal," Morgan continued.

"Definitely," Hotch nodded.

"So we know you were using, and we know Atocha was your only option as a supplier," Morgan mused.

"So let's try this again," Hotch stated, "did Eli Atocha supply you with cocaine in prison?"

"Yes," Dunn replied.

"Okay," Hotch said continuing, "how did you pay for the drugs he provided you with?"

"I have money," Dunn replied.

"Quit lying to me," Hotch spat. "we looked into your financials; your drug use bankrupted you before you went to prison. So how did you pay the Nevaro family?" Dunn said nothing.

"Let me tell you how it went down," Morgan offered. "You told them you'd pay off your debt when you were released. You tossed your daddy's name around so they knew you came from money and so they thought you were good for it. But when you got out of prison, you couldn't come up with the money you owed them, and any cash you did get your hands on, you spent on coke for now instead of paying off your debt. After a year and a half, the Nevaros are pissed and they want what you owe them. And then you remember Caroline's coin collection, but you didn't know she'd moved it to a safety deposit box."

"What happened Brady?" Hotch asked. "You snapped, is that it? You got high, so you could work up the courage to handle the break in. You used your security code to get in, but when you found the coins weren't there you got pissed and you decided to teach Caroline a lesson. You killed her. And the girls, well, they weren't supposed to be home, they were just collateral damage."

From the other side of the window Detective Belem turned to JJ. "He left out the part about the alarm system being turned back on. And you said they were organized, that doesn't fit with an angry guy on coke."

"I know," JJ replied, "he's just trying to get a rise out of him to get him talking."

"Ah, an old school cop trick. I didn't think you guys would mess around with those." Belem chuckled.

"No!" yelled Brady, jerking JJ and Belem from their conversation. He slammed his fists down on the table as he rose to his feet. "I wouldn't. I would never hurt them. I love them."

"Then tell me what you know!" Hotch shouted back.

"For god's sake these are your kids." Morgan said. "You're gonna keep lookin' out for yourself when your kids are dead?" Look at them." Morgan pulled photographs of the bodies out of the folder. "Look at what happened to your babies." Dunn looked away. "And your wife. You see what happened to your wife." Dunn continued to stare way.

"You can't look at what you did?" Hotch said and Dunn yelled,

"I didn't do this, I wasn't even there!"

"No, but you know who was there." Hotch replied coldly.

Morgan held up Addie and Lou's photos. "Are you telling me you know who did this to your children and you're gonna let him get away?" Your kids are dead because of you. Look at them!" Morgan bellowed and this time Dunn did turn his head. "They are dead. You owe them that much. You tell us what happened to them."

Dunn gently touched his daughter's pictures before he whispered, "I don't know what happened."

"You tell me what you do know," Morgan replied.

"It was just supposed to be a robbery," Dunn stated in a small voice. "All I did was give them the code for the security system and tell them where the coins were. They were insured. No one would lose."

"But you didn't know that Caroline moved the coins to a safety deposit box when you moved out," Hotch stated and Dunn shook his head.

"They sent Atocha didn't they?" Morgan questioned and Dunn nodded. "You were his mess to clean up, he vouched for you in prison and when all he got in that trunk was some tree ornaments he thought you had set him up and he was pissed."

"So he taught you a lesson," Hotch continued, "and he killed your family so you would know he was serious about collecting and not to double cross him again."

"No one was supposed to get hurt," Brady said as tears slid down his face. "They were just supposed to take the coins and leave. Caroline would be at work. Addie and Lou would be at Yale and Cory would be at school."

"Cory," Hotch said, "they left her alive as a message to you – that you still have something to lose."

Dunn nodded. Morgan shook his head. "Do you know how long you've been at this police station? Atocha thinks you're in here talking and he's gonna be even more pissed. He got a taste of killing when he murdered your wife and he liked it. If he thinks you're in here talking he's gonna try to hurt you again. He's gonna go after Cory again."

"Oh god." Dunn cried, as he dropped his face in his hands.
