A/N: shortish chapter but wanted to give you a Christmas gift! Hope everyone enjoyed your holiday!!

Fyi: I remember a lot of the streets they use in the show, but I don't remember all of them. So anything with an actual address will be made up in my story.

Chapter 18

Back at their house Antonio was a wreck. Hank ordered him to stay out of the investigation , but it didn't work. There was no way he would just sit this out, so when Kelly showed up, Hank requested he and Matt stay with Antonio to stop him from doing anything drastic. The team split up with Jay, Hank and Hailey going after Ken. Kim and Kevin pulled pod footage from the street. It was determined the assailants had broken in the back door, and this hadn't been a robbery attempt. Adam was dumping Kat's and Ken's phones for all activity.

Matt and Kelly went with Antonio as he talked to his neighbors. They needed him away from the crime scene – He kept trying to go in the house and take over. They knew he wouldn't calm down until he had some sort of job to do, and Hank gave his blessing.

The first stop for Hank, Jay and Hailey was Kens attorney. They pulled her out of her house and had her dragged to the district under threat of prison time for impeding an investigation if she didn't cooperate. After questioning her they found out the guys Ken owed were some pretty shady people, Mark and Rodger Valdez were the main ones, brothers that ran a drug running operation out of the South side of Chicago. Jay and Hailey got a warrant for their house, which ended up being clean. Adam ran their phones and came back with the link to Ken, the three shared a bunch of texts over the last few hours. Everyone met back up at the district to run everything down, including Antonio , Kelly and Matt.

"So what do we know so far?" Hank asked, and had 5 people start talking at once. He held a hand up. "Ruzek, go."

"Well I pulled muds and luds on every phone. Kat hasn't had anything strange come across hers, no out of place texts or calls. But Ken, he's been messaging these two" pointing to the photos of the Valdez brothers " All night long." He handed out print outs of the text messages. "This one is from about an hour ago. Ken – tell me you got the package. Now I'm going to assume the package is Kat…" he stopped when he heard Antonio growl.

"This bastard said he wasn't involved . Kat believed him." He slammed his hands down on the nearest desk. "Sarge, give me 5 minutes with him."

Hank knew the anger Antonio was feeling , he felt it too. "You'll have to get in line. Atwater, Burgess. We get anything on the pod or surveillance footage?"

"Yes, found a black SUV that pulled up into the alley behind the house. Looks like they picked the back door lock, one male offender entered there, the other came around to the front. It's not a great angle, but we can make out a part of the plate. Too dark to run facial recognition though." Kim was on her computer, showing the video to the group. "We see the one male enter the back holding something in his hands, then about 5 minutes later they both appear, carrying what looks to be…" she trailed off.

"We think it's Kat Sarge." Kevin finished.

"You think? Why don't you know?" Hank peered at the computer. "Is that…"

"What? What is it?" Antonio couldn't stand it, he rushed over and pushed his way to the computer screen. He stood staring at the image in front of him. The two men were carrying a plastic tarp, with something rolled up inside of it. His voice cracked "Is that Kat?" he backed up slowly and bumped into Matt and Kelly, who held him up before his legs gave way.

Kim shot him a sad look and nodded "We believe so. We don't see anything or anyone else after they leave. The whole thing took less than 10 minutes. "

Jay spoke up "With the amount of blood that was at the scene, it looks like they knocked her out so they could carry her without a struggle."

"No neighbors mentioned hearing any gun shots or loud noises. " Matt mentioned "So it seems probable they knocked her out ." He still had a hold of Antonio's shoulder and gave it a squeeze.

"Where is Ken Bowman. I want him in the cage, NOW." Hank barked. The team gathered their coats and all headed out to his LKA, leaving Matt, Antonio and Kelly at the district. When they didn't find him there Adam pinged his phone, which had just received another text . Mark- your package is secure. The ping put him at a bar on Wabash, so the team hit it. They found Ken sitting at the bar, like he didn't have a care in the world.

"CHICAGO PD everyone remain calm! Kenneth Bowman, we need you to come with us." Jay was first in the door, making sure no civilians were in the line of fire, while keeping Ken in his gun site.

Ken took a sip of his drink. "This feels a little like déjà vu… am I being accused of something again ?"

"Put your hands on your head and turn around slowly. We need to ask you a few questions. " Jay kept his gun on him.

"I need you to talk to Kat. She can straighten this whole thing out." He smirked and put his glass down. "I'm reaching in my pocket for my phone ."

At that moment Hank stormed in, walking up to Ken and pointing his gun straight to the mans temple. "Do it, I dare you."

"Sergeant Hank Voight I take it? Have you talked to Kat yet? She was going to set this whole thing right." He flinched a bit when the cold steel pressed against his temple harder.

"She's been kidnapped, but you know all about that, don't you. Get up" he grabbed the man by the shirt "You're coming to the district. " He pulled him up off the stool and shoved him at Adam and Kevin who were standing next to Jay, guns drawn. "Get him in the cage."

"Wait, Sergeant what do you mean she's been kidnapped? I talked to her today, she said she would talk to you!" the man looked confused. "I don't understand!"

Hank reached in his pocket and took out the phone they had pulled the texts from. He handed it to Adam who verified the text was there, handing it back to Hank. "You see this? What package are you talking about? Huh??"

Ken looked wide eyed "That's NOT about Kat… Sergeant I wouldn't hurt her."

They shoved him in the back of a car and drove him back to the district. Hank pulled him out of the back seat and threw him into the cage, when Antonio walked downstairs followed by Matt and Kelly, then Adam. They had to hold him back from going after Ken when he saw him.

"Hank, let me in there with him! I'll get a confession from him…" Antonio's face was red.

"Antonio you can't be here. Guys take him upstairs. NOW." Hank pointed to the door and the men pulled on Antonio's arms.

"Antonio come on. You don't want to do this, let Voight take care of him." Kelly tried reasoning with him but he wouldn't budge.

"Wait, is this the guy that stole Kats heart? When I saw her today I could tell she was different … "Ken acted genuine . "Listen you all need to know , I apologized to her about my actions years ago . I told her I haven't been doing these things to her, and I definitely didn't do this. I'll help any way I can." He turned to Hank. "Sergeant, I know it doesn't mean much but I couldn't do this… I wouldn't. " His face seemed sincere… or he was a stellar actor.

"Bring him to interrogation. " Hank ordered Adam, who pulled the man from the cage and brought him upstairs. The firefighters followed, leaving Hank with Antonio.

"I know okay. I get it." Antonio held his hands up in surrender . "I can't just sit around and do nothing, Hank I love her and she's out there. We need a lead, something . " He scrubbed his face with his hands in frustration.

"I know. I want to put a bullet in this guy for what he did to her, but we need his help. Let me handle him, you go to my house. Get a shower, some rest. You can't keep on like this bro, Katie would kill me if she saw you right now. " he slapped the younger man on the back. "I'll call with any updates." He handed Antonio the spare key Kat had given him back and practically forced Antonio out the door.

Kat concentrated on her breathing , trying to keep the nausea at bay. The man that had come in the room had mentioned Hank, and how when he was distracted they would strike. That meant she was just a decoy but she didn't know why. She wished she had told Antonio she loved him in that message… it might be the last time she got the chance. Kat shook her head slightly and cursed at the pain. She couldn't think like that, she had to get out of here. She became quiet, and she could hear what sounded like metal clinking… a chain hitting something. She took a deep breath and smelled… water. She was near the lake or the river... Her eyesight had gotten used to the darkness and she could make out concrete walls, it looked almost like an abandoned warehouse of some sort? She heard noises again so she sat back down on the filthy mattress, curled up in a ball , teeth chattering .

Antonio walked into Voight's house, petrified and angry. He knew not being at the district was the right thing to do, but it didn't stop his gut from twisting. This woman meant everything to him, and he couldn't do anything for her. He immediately retreated to the shower, hoping to get some clarity in the hot water.

Instead he thought about Kat. Her smile when she looked at him...how she would make little noises when he kissed certain spots...how her hand fit perfectly in his. When she laughed really hard at something, sometimes she would let out a cute little snort, which always caused her to turn bright red but didn't stop her from laughing . Mostly he thought about her eyes. He couldn't get enough of those eyes, looking at him with such love… They turned blue when she was happy and grey when she was turned on…he slammed his fist into the shower wall when he realized he might not see those eyes again. He got out of the shower threw on clothes he had grabbed from his house ,then retreated to the kitchen . There he grabbed a beer from Hanks fridge , and jumped a foot in the air when he heard a noise behind him.

"Jesus Halstead. What the hell are you doing here?"

"Voight suggested I keep you company. I think to make sure you didn't come back until you had gotten some sleep." He glanced at Antonio's hand , which was bruised and bloody.

"Shower wall, it's fine." Antonio grabbed another beer from the fridge and handed it to Jay. "I'll sleep when she's found. Have you come up with anything yet?" They both went to the living room and sat down.

Jay wanted to make a smart remark about the wall not being his enemy, but he bit it back. His friend was hurting , and he understood the frustration and anger Antonio was feeling. He was feeling it too, although maybe not to quite the same degree. After Kat and Antonio became official, Jay was happy to remain her friend. Their friendship was important to him, even if it was a bit strained at first, but Jay never stopped caring about her.

"He's in interrogation with Voight right now. Figure we will hear something soon." He took a pull from the bottle Antonio had handed him, and hoped his assumption was right.

Ken was in interrogation, but wasn't saying much . He stuck to the story of the texts being about a shipment of drugs, and that he had no clue who had Kat.

Hank wasn't about that. He had who was left at the district start from the beginning, looking for connections , grasping at straws.

Kat heard the men talking outside the door before they came in, and prayed this would all be over soon. If her father figure had taught her anything, it was to never let the enemy see you upset. So she took a deep breath and waited .

The younger of the two walked in , carrying a blanket. Kat would have jumped up and kissed the man if he hadn't kidnapped her. She had only changed into sweats and a hoodie, no socks or shoes after her shower so she was freezing .

"Here. Figured you might be cold. " He handed her the blanket and turned to walk back out the door.

"Thank you! I really appreciate that. I'm sorry, I don't know your name. Mine is Katherin , but everyone calls me Kat ." She wrapped the blanket around her and rubbed her arms trying to get warm.

The man turned back around and opened his mouth to say something when she heard a shout from outside the room. "What the hell are you doing?" the older man that had pointed the gun at her earlier stood in the doorway. "This isn't the Ritz, why are you giving her a blanket ?"

"Bro she's cold. I'm not an animal." The younger man smiled at her and walked past the other one through the doorway.

"Don't get comfy little girl. You won't be here much longer." The older man waved his gun at her. "Your daddy will figure it out sooner or later."

"Figure what out exactly? Maybe if you tell me what you're after I can help ?" Kat was starting to get feeling back in her arms so she went to rubbing her legs.

"Nice try . You think you're clever don't you?" he sneered at her. "Well you aren't. As soon as we get the go ahead , we'll be done with you."

"Go ahead… from Ken right?" she took the chance and by the look on the man's face she guessed right. "Ken and I go way back… he wouldn't have wanted this. In fact he told me he wasn't involved in all the things that had happened to me. But let me guess, you were ?" Another correct assumption.

The man laughed "He wasn't involved? He's the one that orchestrated the entire thing." The man walked closer to her, staring. "I don't see why you make him all worked up… although maybe I'm not getting the whole picture. " He was uncomfortably close to Kat now, who was having a hard time keeping calm. At that moment she heard a beeping noise, and both she and the man looked down at her wrist. "What the hell is that ??" he yelled pointing the gun at her.

Kat held her hands up "Its just my heart tracker. I wear it everywhere, it's letting me know my heart rate is elevated. I've had to wear it since…" she thought about whether she should tell him the story and decided to do it. "Ken stabbed me about 5 years ago. I almost died, so I wear this to remind myself to take care of my heart." Not entirely true, but the man didn't care.

"Oh." He seemed at a loss for words, so he turned around and walked out of the room, slamming the door behind him.

Kat let out the breath she had been holding. In reality it was a fitness tracker that was GPS enabled. She prayed the team would figure this mess out soon. She cursed Ken , and cursed herself for believing even for a second he had nothing to do with this.

Antonio had started to doze off when he bolted upright in the chair, causing Jay to sit up too. "What is it Tony??"

"Her wristband!" Antonio jumped up and started pulling on his shoes and jacket. "You drive, we need to get to the district."

Jay was lost but he did the same and followed Antonio out to the car.

When they got there and ascended to the bull pen the rest of the team looked as frustrated as Antonio felt earlier. Hank saw them come up the stairs . "I thought I told you to get some rest." He turned his stare towards Jay who shrugged.

"Kat wears a fitness tracker. Like all the time, she doesn't take it off. Those things are GPS enabled aren't they? "

"Yes!" Adam did some digging on the computer and found Kats tracker , and where it was showing her to be. "Old abandoned metal factory on the river. 2509 E 34th ST. " The team loaded up and waited downstairs for the signal to move.

Kat was appreciative of the blanket but she was still freezing. Her fitness tracker indicated her heart rate was slowing down, and her head was still fuzzy, so she knew she wouldn't last much longer before passing out. She heard the door open again and saw the nicer of the two men holding her with a bottle of water in his hands. Crossing the room he knelt down and held out the bottle to her.

"I'm sorry about my brother, and about the situation . You seem like a nice girl, you don't deserve this."

Kat took the bottle from his outstretched hand and quickly drank most of it before responding "I don't know why Ken would want to do this. I can't get him his product or money if I'm dead. "

The man looked at her wide eyed "We aren't going to kill you. No you're just our ticket to the money. Mark's gonna call your dad and ask for a ransom, that's all."

She took note of the name he let slip. "What about Ken? I'm sure CPD has re arrested him by now." She took another drink from the bottle "How does that work?" she wanted to keep the man talking maybe he would let something else slip.

"He has been. But he won't be there for long. Listen, I am really sorry about this whole thing. "

Kats eyes started to get heavy. "You… drugged me?"

She could see the man's face staring back at her, but she dropped out of consciousness before he could respond.

Hank phone buzzed with an unknown number as they were vesting up. He put it on speaker "This is Hank Voight."

"Sergeant , I believe you have someone in your precinct who needs to be released. In exchange for him and 100 thousand dollars I will hand over your daughter. " came the voice over the line.

Antonio started to respond when Hank stopped him with a stare. "You're talking about Kenneth Bowman . How about this. I keep him, and I give you the 100 grand. "

"Sure , you could do that. And I could send you your girl back in pieces. " That comment caused the entire team to get angry. "Bring Ken and the money in an hour, I'll text you the address. Come alone Sergeant. "

"I need proof of life. " Hank hated uttering the words. He heard his phone ding indicating a text had been sent and the line disconnected . When he opened up the picture he saw Kat, unconscious laying on a mattress in a dark room. There was a water bottle laying next to her, which made Hank realize she had been drugged. The next message gave him an address that was not the building her tracker was putting her in. "I want all of you to stake out the building at E 34th . I'll go to this location they sent me with Ken."

"Boss, you need back up. " Adam piped up. "Let me and Atwater follow you. You can get that much cash?"

"We won't need it."
