Given what Booth and Cullen had disseminated about the man, an entire tactical team had staked out a perimeter around Mike Corrigan's home. Corrigan should have seen it coming a mile a way given his Special Forces training, but he slid out of his Ford F-350 and sauntered up to his front door like he didn't have a clue. For a brief moment as the reality that an FBI net had closed in around him he looked like he was going to panic and run; however, the sound of multiple rifles locking and loading as they trained their sights on him was enough to cause him to drop to his knees and place his hands on the back of his head before going face down on the sidewalk just as the tactical team leader had requested.

It all seemed a little too easy. Something that Booth couldn't seem to make friends with as he paced gingerly back and forth in the observation area outside of the interrogation room that Mike Corrigan now sat in. From outside appearances, Corrigan looked like the all American father of the year. And from the more detailed background they'd pulled up while they were trying to take him into custody, it appeared that he was an outstanding citizen too. Since his discharge from the military he'd coached soccer and football, worked with the Boy Scouts and even managed to squeeze in a little time helping Habitat for Humanity on a regular basis. Yeah, this guy was a real piece of work and Seeley Booth was trying to figure out his approach before he walked into the interrogation room and got him to confess to murdering seven people, because he was sure that Elizabeth Thompson was dead and that he was responsible for it.

"Booth, you seem agitated," Brennan had been watching him ever since they'd gotten the call from Cullen that Corrigan was in custody. She knew that a lot was at stake in this interrogation, but usually Booth seemed a bit more in control than he was right now.

"I'm not agitated…I'm just trying to feel this guy out before I go in there. Nothing about him makes any sense," Booth wanted this guy to be guilty, but he needed to pace himself, see if he could get a confession and find out what had happened to Elizabeth Thompson.

"But you're good with people, Booth; you'll get it out of him," Brennan had faith in science and she had faith in Booth; and neither was a blind faith, but they were based upon evidence and experience over time that both could be trusted.

Booth almost wanted to laugh at how naïve her belief in his ability to get what he wanted out of a suspect sounded just then, but he couldn't. Even if he didn't quite believe in himself just then, she believed in him and somehow that simple faith she had in him gave him just the measure of courage he needed to go in and face a man who in his mind was the face of evil. He offered Bones a smile and stepped towards the doorway, "Thanks, Bones."

"For what?" Brennan looked a little confused; she hadn't done anything that she thought he needed to be thanking her for.

Booth glanced back at her, "For just being you," He shut the door behind him and strode purposefully with his cane to the door leading into the interrogation room.

Brennan felt the corners of her mouth twitch upwards into a smile; she was still trying to get used to this feeling she had when Booth did things that couldn't be categorized as 'friend' or 'partner'; they were decidedly more affectionate in nature and she was doing her best to receive them; she'd missed out on so much of life by disengaging herself from the people in it that despite the discomfort of it all, she wanted to embrace what was happening between her and Booth.

Mike Corrigan glanced up at Booth walked in; he noted the cane and the disdain on the man's face and frowned himself.

"Mike Corrigan," Booth flipped through a file as he considered just how he wanted to proceed here, "Special Forces, tour in Vietnam, trained sniper, medical discharge," Booth glanced up and stared the man down, "Did I miss anything there?"

Corrigan could tell that this Agent Booth was pissed and that for some reason he was the target of it all, "That pretty much sums up my service record. The discharge was because they discovered I had an undiagnosed heart condition when I had surgery for a shoulder injury I got in Nam."

"Tell me about your brother-in-law Walter Fitzpatrick," Booth wanted to see if just the mention of the man's name might give him a clue as to where this was going if he didn't already.

"Walter?" Corrigan looked a little confused, "He's a good guy. Used to work for you guys; retired when he was diagnosed with Parkinson's Disease a few years ago." Somehow this was all related to Walter and he couldn't understand why. Had Walter done something to betray his country? That just made no sense to him at all.

Booth gritted his teeth a little; this guy was trying to play him and he didn't like it one bit, "Do you know who Elizabeth Thompson is?" If this guy was going to beat around the bush, then he was going to get straight to the point; he wanted to get this case laid to rest so that the victims could finally get some justice.

Corrigan furrowed his brow for a moment and then a smile stole over his face, "Yeah, I knew her. She was Walter's carpool partner and she set me up on a blind date with one of her friends years ago. Lila Montgomery was her name," Corrigan seemed to be taking a walk down memory lane and then his expression clouded over, "We dated for a little over a year; I thought maybe I might marry her, but she broke things off pretty abruptly after Elizabeth disappeared; never heard from her after that, and then I met my wife Ella so it didn't really matter."

"Lila Montgomery is dead," Booth let those words fall like a ton of bricks to see if it would shake this bastard out of his sentimental reverie.

Corrigan looked shocked, "Oh, God." Clearly the FBI wasn't informing him of her death as a community service; the fact that just a moment ago this agent had brought up Walter's name made him wonder if there was a connection, "How did she die?"

"Cut the act, Mike, Lila Montgomery was murdered, the same way that Elizabeth Thompson was probably murdered, and the same way four little boys who just happened to be in the wrong place at the wrong time were murdered. And the same way one of my agents was murdered. You, my friend, are looking at seven counts of capital murder," To emphasize his point, Booth leaned over the table and glowered at the man.

All of the color seemed to drain out of Mike Corrigan's face as Booth's words sunk in and his hand reached up to clutch at his chest just before his eyes fluttered shut and he slumped forward in his chair.

Booth's eyes widened as he realized that the man was having a heart attack, "Medic! I need paramedics in here now!" Despite the fact that he was convinced that the man had killed seven people and would probably sentenced to death once he was convicted, Booth wanted to make sure he stood trial and he immediately began administering CPR.
