Brass entered the room unassumingly as he sized up the young suspect. He had gotten the impression that this kid may have been roped into coming down to the station and asking for the missing gun for someone else; he certainly did not expect someone with criminal savvy. Still, you could never underestimate what someone of any age was capable and he put on his game face knowing that the three CSIs were behind the window taking in every nuance of the interrogation. "Well, Billy, it seems you and I have something in common." The grizzled detective placed his hands flat on the table in the center of the room and flashed a smile that looked far friendlier than it actually was.

The suspect looked doubtful. "I don't know what you're talking about." Billy was visually nervous; he'd obviously expected that he could simply walk into the police station and waltz right out with the gun in hand. The fact that it had been used in a homicide and an assault on a police officer didn't even seem to register with him.

"Yeah." Brass leaned across the table and quirked a single brow. "You and me want the same gun; problem is, I'm not sure why you think it's yours." Brass was fishing and he knew it, but he'd gotten information for less and this nervous young man looked like he just might give out enough for them to find out if someone else was behind their shooter.

"It's mine...I need it back." The young man looked scared as hell and certainly wasn't thinking about what was coming out of his mouth.

"Well, we're going to need some proof." Brass smirked and then settled himself in the chair across from Billy. The detective gestured broadly and then crossed his arms over his chest waiting for some sort of answer.

Billy's eyebrows shot up. "How am I supposed to do that?" He clearly was in over his head and he was just beginning to pick up on the fact that he might be in trouble.

"Well for starters, you could give me the serial number?" Brass felt like this was going very well. He just sat back with an expectant smile on his face.

"I can't do that." Billy stammered and then swallowed hard. "It doesn't have a serial number." This kid clearly looked scared and it wasn't just because he was sitting in a police interrogation room.

Brass leaned forward, his friendly smile gone. "Oh, I see...you filed it off before you lent it to your friend Gunther." The widening of Billy's eyes was enough for Brass to confidently continue. "The thing I don't get is what a kid like you has to do with a thug like that." Brass was staring the young man down waiting for him to crack.

"He stole it from me...I don't know anyone named Gunther...if I don't have that gun back, my uncle is going to kill me." Billy broke like a dike.

Brass smirked. "And just who is your uncle?" He knew that they could find out whether Billy confessed or not.

"Frank Sutherland." Billy's eyes were wide and he was obviously scared to death that he'd mentioned his uncle's name.

"Why don't you tell me more about Uncle Frank?" Brass glanced over at the CSIs behind the two-way mirror to indicate that he thought they'd broken the case wide open as Billy continued to spill.

Warrick let out a soft chuckle and shook his head. "Boy, Brass played him like a roulette wheel." He was always amazed at the ease the detective could solicit information out of a suspect.

Catherine smirked. "Well now that we have a little more to go on, I think we'd better get back to the lab and track down whatever we can on Billy's Uncle Frank." They were going to have to see if the evidence tied Frank to their original homicide before they could draw any conclusions about guilt or innocence. Although from where she stood, Catherine was almost certain that they would find a connection, she had a feeling about this one.

"I'll get right on that." Greg was eager to get to the bottom of the case and since he knew that Catherine would most likely ask him to start digging up information anyway, he thought he'd just volunteer instead. Besides, the sooner they wrapped up this case, the sooner he'd be able to go home and actually sleep, something he'd had a great deal of difficulty with since they'd begun the investigation.

"I'll see if we can find any connection to Walter Bradley." Warrick knew that if they could draw a connection to their original victim they would have a much better chance at obtaining a warrant to search Frank Sutherland's house."

"Good." Catherine would wait until Brass had finished up with Billy and then she would see if Warrick or Greg had managed to come up with anything. She heard the two men slip out and she focused back in on the interrogation.

Billy was practically sobbing. "He told me he'd kill me if I didn't get the gun back...and he'd do it too; he's killed guys who worked for him before. Please don't tell him I was here; I don't want to die."

Catherine arched her brows as she watched; this kid could be a very good actor or he could be just as scared as he looked. And at this point she wasn't going to rush to form an opinion. The sound of the door opening caused her to glance over and her eyes widened in surprise and then narrowed. "Gil, what are you doing here?" This was her case and he was supposed to be hands off.

"I was hoping that I could talk to you." There was something about the expression on his face that just seemed off. Or maybe it was the fact that he had sought her out rather than wait until she'd stopped by his office. This was definitely unusual for Grissom.

Catherine pursed her lips together. "And you came down to PD while I was observing an interrogation in a high profile murder investigation?" Clearly the man wasn't thinking clearly.

"It's important; I wouldn't have come down here if it wasn't." Grissom looked like he felt physically ill.

Catherine's immediate thought was that something had happened to his mother. "What is it?" She knew that the interrogation was being videotaped and that she'd most likely review it again anyway, so she focused on her friend.

"It's Sara." Grissom's words faltered.

"Is she ok?" Catherine knew that despite the way he tried to hide it from everyone else that he had feelings for the younger woman.

"Yes, she's fine I think." Grissom took a deep breath and continued. "She's dating Nick." Clearly the expression on his face indicated that this information was on the same level as announcing that the Bay Checkerspot Butterfly was extinct.

Catherine tried to hide her amusement; she knew he was probably heart broken, but in her opinion he had no one to blame but himself. Just how long did he expect her to pine away for him if he was never going to act on his feelings? "Nicky's a good guy, Gil."

"I know that." Grissom took a deep breath; Catherine was one of the few people he trusted and this was difficult for him. "But I'm in love with her."

A small smile tugged at Catherine's mouth as she looked at him with compassion. "Gil, just how long did you think she was going to wait? Maybe if you'd let her know how you felt about her, you might have had a chance with her." In fact she knew that Gil would have gotten that chance if he wasn't so hard headed.

Grissom's face looked pained as he confessed to his longtime friend. "I did tell her...we've been seeing each other for the last few months...but she left me for Nick."

Catherine couldn't have looked more surprised if she tried.
