Its been a few weeks since I heard anything about Doyle and decide to give Morgan a call to find out what's going on. It goes straight to voicemail so I hang up and dial the next number that comes to mind. "Maddison, is everything okay?" Spencer's friendly concerned voices oozes through the line.

"Spencer, hi. Everything is good. I was just wondering what's going on with the search for Doyle?"

He responds with nervousness "you called me? Why not your father?"

I nervously chuckle back "because we're not really talking right now. I'm sorry, I shouldn't have called." I mutter out, really realizing now this was a mistake.

He stops me before I could hang up "no, it's fine. It's good to hear from you." He lets the words sink if for an awkward amount of time.

I speak into the air "thanks."

"As for Doyle, we're still actively searching for him. We are taking on other cases as well though." He tells me honestly. I know that means they have no leads on where he is or any chance of finding him if they keep themselves on this case over others.

"Alright. Thanks Spencer." I say, ready to hang up and get back to work.

Spencer doesn't get the hint though and goes on "You taking precautions up there? He really could be coming after you, he did threaten that at his last hearing."

I sigh "I remember and yes, I am being careful. Don't worry about me."

"I'll always worry about you." He responds back before thinking about what he was going to say. He used to tell me that was one of his favorite things about me, I turned his brain off and he just said what he wanted to say.

I smile at his words "and me, you. Bye Spencer." I say and he returns the salutation before hanging up.

I walk back into the precinct and sit at me desk, getting ready for Benson and Finn to review us on how their on site interview went with the victim. "The glove they found in the sewer grate came back clean." Finn starts off as Benson pins a photo to the board. "No DNA. No prints."

"No DNA? Well, there goes codis." I say, knowing it's not always easy here.

"Look, it was worth a shot." Carisi agrees.

Benson explains "we think the perp knew her, so-"

She goes to further explain but Carisi jumps in "so we re-canvass the area, video cams, parking tickets, I crosscheck the tea shop's credit card receipts with known offenders." He smirks at our boss "I know the drill."

He sits down across from me opening laptop. "Fantastic." She tells him.

Rollins walks in hurriedly towards her desk "hey, sorry I'm late. Con ed was on my block. The transformer was out. So no electricity, no hot water. I had to take a shower at the gym. - It was-"

"Rollins, a word of advice." Benson stops her "when you're coming up with an excuse, don't oversell."

Carisi chuckles as do I and Rollins responds "copy that."

Finn fills her in "the perp wore latex gloves. We think he stalked her."

"Okay, so you put it into vicap?" Rollins asks looking at Carisi. He is about to say something when she continues. "You did, right? You have a detailed M. O. I mean, vicap is a comprehensive nationwide database." She finally sits opening her own laptop.

Sonny tries to cover his short slip up "yeah, I know. I was just about to get into that."

Rollins ignores him and begins typing. "Okay, early Sunday, a Caucasian male assaults Annie Lin. Now, she's young. She is Asian. He chokes her and uses latex gloves. What else?"

"He hummed." Finn clues us in.

"He what?" I ask, unsure I heard what I heard.

"He hummed." Finn says again. "Annie remembered the perp humming while he assaulted her."

Carisi pushes it off "he hummed? So he's musical."

Rollins taps her desk a moment "you might think I'm crazy, but was it gospel music?"

Benson answers "Annie said it sounded like a church hymn."

"Before I left Atlanta, we had a humming rapist that choked out his vics. I mean, it wasn't my case, but it was only back in 2008? 9?" Rollins tells us, thinking back to old cases at her old precinct.

I nod and Benson directs "Okay, well, Atlanta's easy call for you, right?" Rollins nods nows. "So Carisi, since you were gonna do it anyway how about you take over vicap with Grey? Check recently released parolees, offenders, okay? This guy had to come from somewhere."

Finn speaks up then, getting off the phone call he took "and he may not have gone anywhere. At the midtown magnet school just disclosed to her counselor, early morning, a guy choked her out."

I sigh along with someone else and Benson leaves with Finn to go interview the girl "let's go."

I drag my chair over to Carisi's side of the desk and we begin our Vicap search for the perp. "Click on that." I direct him a few moments later as he takes forever to go through the system. "No, scroll down, there's still more to input."

"Learn all of this at the FBI?" He asks, typing in the specific M.O of our perp.

"Just something I picked up while in prison." I joke and he looks at me strangely "of course from the FBI Carisi, sheesh." I slap him lightly on the arm and he awkwardly chuckles back "okay, now just click the perimeters you want to search and then we're good." I tell him. He specifies North America as our search perimeters and the loading begins.

We sit scrolling through report after report of incidents similar but not matching our perps M.O. Rollins returns from grabbing a file and Carisi engages her "so we're going over these vicap responses. You know how many rapists sing, hum, or whistle to their victims?"

"Mmmmm." She hums back not really fully engaged.

"A lot." He returns throwing his pen down. "You got anything?"

"Probation, no. Immigration, no. And the military hasn't gotten back to us yet." She tells him.

I shake my head "Oh, big surprise." Rollins phone rings and she looks down at it, making a weird face. "You okay?" I ask her.

She nods "yeah, it's- it's Atlanta." She accepts it. "Captain Reynolds, thank you for calling back."

Just then Benson and Finn return from their interview and Carisi asks "hey, you guys get anything from the new vic?"

"She remembered the latex gloves and the humming." Finn responds "No DNA. Didn't see the face. This guy targets his vics. He knows their routines."

"Any matches on vicap?" Benson asks.

"Yeah, too many." Carisi informs. "You know, unless this guy worked every city in the country, then I got to figure out how to narrow my search."

Benson puts her hands up, knowing the job all so well "without DNA, it's not gonna be easy."

"Well, let's hope we can figure something out before we have more victims." I answer, not wanting to surrender defeat.

"There's three open cases in Atlanta, same M. O." Rollins tells us now off the phone. "I mean, the latex gloves, the humming, the choking out. And they did the rape kits on all three of them but they never had them tested."

"Oh, not that again." Benson shakes her head. "Are they testing them now?"

Rollins returns "they think they're in storage."

"Along with what? Thousands of others?" I ask, knowing how far back most precincts are on testing their rape kits.

"Yeah, but they're looking at least, right?" Carisi asks her.

"Oh, and not very hard." Rollins explains. "These cases are six years cold."

Benson doesn't accept that "well, ours aren't. Rollins, if I send you down there, do you know where to look?"

Rollins weighs her head from side to side "it's still a boys club down there, but if I act helpless and bat my eyelashes—"

Benson interrupts her from going on "So, do that."

Rollins nods and Carisi asks "how about I go with?"

Benson answers "how about" she pauses for a second "you take Fin."

Trevor Langan walks in, asking to speak to Olivia. She goes into her office with him and shuts the door behind her. "Guess we're on desk duty." I say to Carisi whose standing now, happy Trevor didn't look my way.

"There's too much, we're gonna need to put in for O.T. later." He tells me looking down, frown lines forming around his mouth.

He goes to move to ask about it but I stop him "I don't think now's a good time to interrupt!" I call out, causing him to hesitate.

He throws his hand out at me like it's no big deal and knocks on the door before opening it without a response. I can hear it from here that she tells him it's not a good time but he gets out what he needs to get out and she agrees to O.T. He comes back over to the table "easy." He smiles, taking his seat and scooting in closer to look through more perp files.
