"Voight stood in the middle of the crime scene as a handful of Crime scene investigators snapped pictures and collected samples. No sign of Jay had turned up and currently Antonio, Haley and Adam were canvasing the building to see if anyone heard or saw anything. The flash of a camera caught Voight's attention; a CSI was focused on a lamp that lay broken on the floor, the shade was crumpled, and the bulb shattered. It was the weapon no question that had put Will in the state he was in, the metal stand of the lamp lay bloody, carelessly thrown ten feet away from its parts. Blood splatter had been sprayed up the walls, it wasn't hard to see from the trajectory that Will had been laying on the floor when he had been beaten.

"Voight," Antonio appeared in the doorway. He was stunned by the crime scene yet again as he crossed the yellow tape after placing the booties over his shoes. When they first arrived, they had all been stuck in place, not sure what had happened, but it was all overwhelming, so Voight had sent them out. Now, as Antonio stepped back in the coppery smell attacked him, it hung heavy in the air.

"What do you have Dawson?"

"Canvased the whole building, the neighbor below Jay said he heard loud stomping and a few thuds and the one next door said he heard some shouting."

"Shouting but he didn't call 911," Voight questioned.

"His excuse was Jay's a cop, so he didn't see the point, also this man was in his late 80s, spoke highly of Jay."

"So, no witnesses in the building, maybe Adam and Haley will find something."

"Where we able to track Jay's phone?"

"No need, his phone and wallet are here, nothing is missing."

"I don't like this," Antonio voiced his concern. "There was no forced entry, nothing is missing and all we have his Will beaten close to death."

"Maybe they knew their attacker," Voight had to have such wishful thinking. Given everything they had so far there was a possibility that no one wanted to jump to. Hank watched as one of the investigators placed the metal base into a bag, sealing it shut.

"We've got everything we need here Sargent Voight; we are going to take it back for processing.

"And put a rush on it," he demanded.

As Voight was barking orders Haley and Adam scanned through the blizzardy streets to find some sign of Jay. The blood trail obviously ended with Will collapsing in the snowbank, there had been no indication that he had been with Jay at the time of escape. It had been silent out, the blizzard had boarded up much of the Chicagoans, it had been sheer luck that a couple had braved the storm for a bite to eat or Will wouldn't have been found in time. The heat was on full blast in the car but still Haley's fingertips felt frostbitten for the ten minutes she had just spent out of the truck. Adam's cheeks were a rosy red where the cold had nipped at him, like a thousand little needle pricks.

"I can't see a thing," he complained as he tried to navigate his way up and down the streets while keeping a look out in every passing alley.

"I don't see anything; I don't think he is out here." Haley sounded defeated after three hours of searching there was still no sign of their friend.

"Of he was he would be a human icicle like Will," though it came out as a joke he was pretty serious about it and Haley knew that but still gave him a light back hand to the shoulder. She was growing increasingly worried about Jay, like a snowball in an avalanche. They had combed each street at least five times each surrounding Jay's neighborhood, anything more they didn't think he would make it that far.

"Maybe we should call into Voight, if we haven't found him by now, I don't think we will."

"I guess," Adam groaned in frustration. He pulled his phone out and clicked Voight's contact number waiting as it rang.

"Voight," the gravely voice of their boss sounded.

"Boss, we have searched these streets a million times over, no sign of Halstead." The other side of the line was quiet for a moment and then he could hear a muffled conversation between Antonio and Hank.

"Alright, we are gonna meet back at the precinct, we will meet you there."

"Roger," Adam confirmed before hanging up. He looked at Haley, both of them were a little frustrated by the lack of good luck in this case but they had been given their orders and now they dove back, both of them still keeping an eye out.

Kim and Kevin had returned first from the crime lab where they dropped off the evidence from Will. They had been able to get back a few of the photos and the DNA testing of the blood, there was only one donor; Will. Kim taped the department photo of Jay up on the board, it was always absolutely heartbreaking when one of their own was up there. She lingered for a moment as she was finishing up the board, it seemed too strange to be their case.

"I just got a call back from the lab," Atwater was running up the stairs. "Only fingerprints on the weapon… they were Jay's."

"Okay well its his apartment they were bound to be there," She rationalized.

"Yeah, perp could have been wearing gloves." He stopped next to her and stared at the crime scene photos, he was surprised at the among of blood that was sprayed on the walls, it was a miracle that with the injuries he had Will was still alive, especially seeing the photos parallel showing Will's bloody, bruised and broken body. They had spent two hours at the hospital before getting the call to head back and in that time Dr. Choi had listed of the injuries that Will had suffered. It was lengthy and both Kim and Kevin could see that the whole Emergency room staff was taking it hard. What they had heard was that almost all of his bones on his left side had been broken or fractured. Choi had voiced how shocked he was that Will had made it as far as he did with a fractured pelvis and Tibia.

"How's Will," Haley and Adam appeared at the top of the steps.

"He's critical, he got one hell of a beating," Kevin cringed.

"Internally he's a mess," Kim added.

"Damn," Adam shook his head, looking at the crime scene photos.

"Any luck," Kim asked hopefully, any little trace would give her some relief, but Haley shook her head.

"This is too damn crazy; we just saw him like six hours ago."

"Six hours ago, and he was fine and now he's missing, what do we got," Hank demanded as he and Antonio ran up the stairs.

"None of the neighbors in the surrounding buildings saw or heard anything from outside," Adam sat on the edge of his desk.

"We got the DNA back on from the crime scene, it's Will's."

"Nothing from Jay," Antonio asked in disbelief.

"There was a small trace amount of blood of Jay's but the majority of it was Will."

"So, they left Jay alone and beat the snot out of Will, that doesn't make sense."

"Unless they needed Jay unharmed," Haley was at a loss with the suggestion.

"Even so Jay wouldn't have sat back and done nothing," Kevin reminded them.

"So, what are we saying," Kim asked frustrated, "That Jay did this."

"No… I mean he…" Adam tried to figure out the words to clear all their minds of the thought be he was just as lost.

"As long as there is no sign of Jay, we are to treat this like Jay is in danger," Voight demanded. "Antonio, me and you will talk to that neighbor that came forward." Antonio nodded and ducked out of the room where the tension was so thick it could be cut by a knife. Kim retreated back to the board and scanned the photos, each one of them more gruesome than the next. Staring at the swollen face of Will made her nauseas and he stomach churned even more when she thought of Jay doing that to him. A photo that the CSI had taken caught her eye, it was a picture of blood splatter but they had also caught the image of a few photos from the table beside the wall. It wasn't super clear but she could see one of Jay, grinning gapped toothed as he held his baby brother in his arms, the one beside it was of Will and Jay outside of Molly's. Kim pulled the photo off the board and showed it to the team.

"There is no way Jay did this," She showed each one of them the photo to prove her point. It slightly worked, none of them wanted to believe this was Jay, it was their Job to prove it. Adam took the photo from Kim and carefully tore away to divide the crime scene and the photos. He pinned the blood splatter pick back to the bottom of the board before grabbing a knew strip of tape and putting the other half between Jay and Will's photo. It would serve as a reminder to help prove that terrible theory wrong. Adam looked at the little boys again, he remembered Jay saying how tough childhood had been but in this photo he was as happy as a clam; there was no way he could do this to his own brother.
