"So what've we got?" Sergeant Hank Voight addressed his Intelligence unit.

Detective Antonio Dawson stepped forward, pinning 2 pictures to the board. "These two, Mary and Colin Harrington. We suspect them of kidnapping and torturing girls." He then proceeds to stick another picture on the opposite side of the board of a severely beaten girl, probably only around 15. "The victim, Jenna Kane confirms that these were the two who kidnapped her and we estimate that they have around 10 other girls trapped where she was"

The rest of the unit exchanged glances. No one liked these kinds of cases, especially Detective Erin Lindsay. She smiled sadly at the board thinking about the other girls and what they must be going through. Usually her partner, Detective Jay Halstead would have sent her a comforting smile or something but he had other things on his mind.

Jay felt confused. His mind was telling him that he knew these people, their suspects but he couldn't pinpoint exactly where he knew them from. "Hey Antonio, did either of them have a record?" he asked.

The older detective shook his head. "Absolutely nothing, not even a speeding ticket" This wasn't the answer Jay was hoping for; it only made him more confused. 'Hopefully, when we catch them I'll get some answers' he thought.

A few hours later, the team were stood on a street corner, just metres away from the house they would be searching in a matter of minutes. Jay and Erin checked each other's vests before nodding to Voight. A few minutes after that, Intelligence were approaching the entrance of the property. Breaking down the door, Officer Adam Ruzek entered the house first with his partner, Detective Alvin Olinsky just centimetres behind him. Halstead and Lindsay followed closely after, checking the next 2 rooms after the ones Olinsky and Ruzek had checked. Eventually, the whole house was clear.

All of the unit were looking around when Officer Kevin Atwater shouted from a different room "Hey sarge, I think you're gonna want to see this" Voight trudged into the newly discovered basement that Atwater was in. Cages were set up in rows, with a thin blanket in each. Each cage was no bigger than a small dog kennel. Most of the girls seemed to still be in the cages, although there were two or three empty ones. Voight set to work on calling some ambos to take the girls to the hospital to get checked over.

IIIIIIIIIIIIIII

After each of the girls were taken to Chicago Med along with Ruzek, Halstead and Lindsay, the remaining members of the Intelligence unit stared bagging up evidence trying to get ID's on some of the girls they had found and the ones who could have previously been in the vacant cages. Antonio was searching one of the cages on the far left side of the room, one of the few that had been without an occupant when something metallic caught his eye. There was a gold chain sticking out from underneath the blanket. Antonio pulled it out to get a closer look and realised it was a locket on a chain. Opening it up he found something that surprised him, a picture of someone he knew.

Pulling out his phone, he dialled Jay's number. It rang a few times before he picked it up.

"Dawson? Everything okay?" He asked.

"Yeah, just a quick question"

"Shoot."

"When we were in the house did you go over to the far side of the room, where the empty cages were?"

"No, I don't think so" a puzzled Jay answered, confusion evident in is voice.

Antonio, thinking it over, decided to tell Jay nothing further over the phone.

"Never mind, I just… uh… thought I saw something and Voight didn't agree with me. I thought you might've seen it too." Antonio lied as best he could but he knew it wasn't convincing. Without giving Jay the chance to reply, he ended the call.

Looking at the locket again he wondered if he was mistaken, if it wasn't Jay in that picture. However, the man in the picture couldn't not be Jay: the hair, the eyes, they just looked too similar. And the guy next to him in the picture had to be Will; he'd recognise that ginger hair anywhere. There was one more person in the photograph, someone he didn't recognise. She must have been around 4 or 5 when the photograph was taken which was probably around 10 years ago judging by the fact that Jay looked to be in his early teens. The girl had red hair similar to Will's however she sported a pair of grey-blue eyes, identical to Jay's.

Whilst puzzling over the locket, Antonio hadn't noticed Voight walk up behind him. "Dawson! What are you doing? You've been back here for 30 minutes already!"

"I found something Sarge" Antonio admits, holding out the locket for Voight to take. He carefully takes the locket into his gloved hand and examines it, eyebrows raising at the sight of the picture.

"Maybe Halstead just dropped it?"

"Not possible," says Antonio "he told me that he didn't go anywhere near this side of the room"

Voight looks at Dawson with a confused look. "You told him?"

"No, I just asked him if he had been there or not. Said I had a disagreement with you about something" Voight nods in approval.

"When he gets back to the district, we pull him to one side and tell him in person," Voight says in a low voice "you never know what his relationship might be to her and I don't want one of my detectives being distracted"

Antonio nodded in understanding. He hoped for Jay's sake that the girl in the picture wasn't one of the missing girls.
