"Okay, the DNA came back to the daughter's boyfriend." Ray walked with Catherine through the hallway.
"He's in the system?" Catherine took a look at the results.
"He works at a Casino. He has no rap sheet. Brass talked to him, he seems to be a nice kid..."
"It's likely that the killer knows they were a couple. We should give him protection."
"Brass' already on it." Ray and Catherine parted ways as Ray went to find Sara and Catherine went into the DNA lab.
"Hey Greg. How are you holding up?" she smiled at her young colleague.
Greg gave her a rather annoyed look. "I'm fine..." getting back to the DNA sample he has been working on before Catherine showed up, it was obvious for Catherine that he was angry with her.
"You do understand why I had to pull you from the case, right?"
"Yeah, of course..." he didn't bother to look at her.
"Greg..." Catherine walked up to him, forcing him to face her. "I'm worried about you. I don't want you out in the field as long as there's a lunatic threatening us."
"Yeah, I know that but..." they were interrupted by Catherine's cell phone ringing.
As Catherine looked at the caller ID and saw it coming from Greg's stolen cell phone, she went off to the A/V lab. Greg followed her.
"Archie, I need you to retrace where this call comes from!" Catherine answered the call. "Who's this?"
"Hello, Catherine. Nice to finally hear your voice."
"What do you want?"
"Nothing. I just wanted to talk to you. You look like such a nice person."
This got Catherine thinking. Was he just trying to intimidate her or did he actually know what she looked like? And if he did, how? "Oh yeah?"
"Yes. But you all look like very nice people..."
"Okay, so you stole a CSIs cell phone only to make prank calls? Or is there something else you want to tell me?"
"Could I please talk to Greg?"
Catherine could hear the guy grin as he said that and she wasn't sure Greg could handle talking to him right now. "Why do you want that?"
"I'd rather tell him personally. So hand him your phone or I'll think about another way to talk to him, you got it?"
She could hear the amusement in his voice being replaced by anger and although she didn't really want to, she decided to let him talk to Greg.
"He wants to talk to you..." Catherine held the cell phone out to Greg.
Greg hesitated for a second but then took the phone. "...Hello?"
The caller moaned. "It's so good to hear your voice again."
While Greg was on the phone with him, Archie was able to trace the call back. Catherine informed Brass about it and he sent a Unit to the place where the call came from.
"How's your rib? Feeling better? Listen, I wanted to apologize. I didn't mean to make you cry... But your friend Nicky is taking good care of you, right?"he laughed devilish.
"What do you want from me?" Greg was having a hard time fighting back tears but didn't want to cry in front of Archie or the guy on the phone.
"Oh good. I hear the cops coming already. You probably didn't think I knew you'd trace back the call, right?" Again he laughed devilish.
Greg covered the phone with his hand. "Archie, call Brass, it's a trap!"
While Archie was trying to reach Brass' cell phone, Greg kept talking to the man on the phone.
"Why are you doing all of this? What's your agenda?"
The man laughed again. "Who said I had an agenda? Maybe I'm just a psycho having fun killing cops, you ever thought about that? Maybe I just want to be friends with you all and can't find a better way talking to you, who knows?"
Greg didn't know what to say to that. He was just worried about Brass and the police officers who were about to go to him. He desperately looked to Archie who couldn't reach Brass.
"Listen, Greg. I'm going to hang up now. I'm expecting company..." He laughed again.
"No! Please, just get out of there and leave them alone!" Greg didn't know what else to say, but he was sure it wouldn't help much.
"Actually I am planning to get out of here. But I have to take care of your friends first..."
Greg heard several shots being fired, loud enough for Archie to hear them, who was standing a few feet away from Greg. Both men just stood there, stone still. They both tried to imagine what was going on.
"I'll get Catherine..." Archie finally said, running to her office.
Greg was still standing in the A/V lab, holding his phone to his ear. He didn't move an inch, he was imagining the worst happened.
"Did you hear that? Nice sound, huh?"
There was a lot Greg would've liked to tell this man now, but he wasn't able to say anything.
"Are you still there, sweetie? Why don't you try calling Captain Brass right now?" he said with an evil laugh.
"We're going to find you... You'll have to pay for what you've done..." Greg said with a trembling voice, hanging up the phone.
He sat down, trying not to break down. It was hard, but he managed to keep it together. Then the phone rang again. It came from his cell phone again.-
"Oh god..." he rubbed his teary eyes, trying to find the strength to answer the call. He let it ring several times but then answered.
"Don't you dare hanging up on me again, Greg! I'm serious. You don't want to see me angry, alright?"
"Please, just tell me what you want from me! How can I make you stop?"
The caller could hear Greg's desperation and was quite amused by it. It's what he wanted.
"Frankly, you'd have to kill me to stop me. But you can't kill me until you've found me. And I doubt that'll happen anytime soon. Talk to you later, Greg."
Archie came back running into the A/V lab. "Greg! Brass is fine! They didn't find the guy, I think he used some kind of router!" he had a relieved smile on his face as he told Greg the good news.
Greg released a deep sigh. He didn't say anything, just smiled at Archie and walked into the break room.
Nick walked into the break room, searching for a cup of coffee, but instead finding Greg sitting in there alone, looking like he just cried. "Hey..."
"Hey Nick." Greg tried to cover up his sad face with a smile.
"Archie told me about what happened. I imagine that was quite a shock, huh?"
Greg nodded. "He's playing with us and having fun doing it..."
"You're not supposed to worry about that... You're off the case for a reason."
"How can I not worry? I feel like this is all my fault and I have no idea what he wants from me..." he looked at Nick with a sad face.
"No, Greg, don't you think that. He just..." in this moment Ray walked in.
"Guys..." Ray's look on his face let the two men prepare for the worst news. "It's happened again..."
The CSIs arrived at the new crime scene. Everyone but Greg was at the scene, as he was still pulled from the case. He wanted to go with, but Catherine didn't let him.
When they arrived, they found a man in his early 30ies with a gunshot wound to his chest. A bag of groceries was lying next to him, suggesting he was on his way back home from a supermarket when he was shot.
"How do we know it was our guy who killed him?" Sara walked up to the body.
Brass took a moment to gather himself. "Because he's a cop." obviously devastated by this, Brass walked away.
The CSIs just stood there for a moment, not believing that the man they were looking for would now hunt the police officers down when they're not at work and killing them.
