A/N: Hey, guys! Sorry I haven't posted in a while! I've been working on a ton more for you, I'm so caught up! But, here is chapter ten! Very suspenseful and packed! Enjoy!

"Why am I being interrogated, police officers?"

"For a case. Do you know him?'

"No...I don't. Sorry to disappoint…" She said, walking away.

"If we don't find this guy we'll be dealing with this all day." Jay mentioned, as they walked away.

"Damn." Antonio and Jay began to walk back to the car.

"Let's go for a few more before we-"

But, in the middle of Jay's words, there was a boom, right behind them. They turned quickly, but were shielding themselves from the strong impact of the an exploding building.

Smoke and debris began to fly at fast speeds. The two fell to the ground. The impact was incredible, considering they were far from the area.

There were screams and commotion for a while, then Chicago fell silent.

In Another Building Nearby:

"Do you know this man?" Erin Lindsay spoke, as her Task Force co-workers stood next to her.

"No, I-" the man was about to answer, until the strong boom was heard there as well.

Everyone was alarmed. Lindsay's eyes turned big, as she then walked over to the window, and saw the explosion in action.

"Sorry, to take your time, we have to go." She said to the man.

"Erin, wait, we're in the middle of som-" her boss tried.

"No! We're police, we were probably going to get called anyways, let's go."

At the Scene:

"Holy…" Antonio said, as he began to rise from the ground. He was covered in gray soot from the dirty dust. He sat on the ground, looking out at the area. There were people on the ground, cars tumbled, some destroyed or on fire. the area felt silent, but there were screams everywhere.

People were running from the exploded building. People were running out, scathed and unscathed. Fire trucks were already heard minutes later in the distance.

Antonio wanted to get up, and walk towards the injured, but he realized, his best friend was with him.

"Jay, you okay? Jay?" Antonio asked, crawling over to Jay, who started to sit up with an aching body.

" ...Uh, yeah. I'm good. You?"

"I'm okay. Let's get you up, we gotta go help." He said. He stood up, then helping to pull Jay up from the ground too. Then, the rest of Intelligence finally arrived just in time. Everyone was able to hear sirens in the distance of the other aids that were coming to help.

Jay felt a little lightheaded and wobbly as he stood, trying to steady himself as Antonio looked him and held his shoulders.

"You good?" Antonio asked.

"Tony, Halstead? You okay?" Voight asked, as Intelligence came over.

"Yeah, yeah I"m good, just got up too fast." Jay replied to Antonio, which also answered Voight's question.

It was hardly an instant before there were even louder screams. They realized a man, dressed in black, running through the streets. His hood was up, but these detectives are too keen to not notice.

"That's him! That's him!" Ruzek shouted. Atwater and him began on foot.

Voight ordered Jay and Antonio to go in the car.

Antonio immediately started the engine and took off as Jay shut the door.

Atwater and Ruzek ran down a main street, noticing the ambulance and firetrucks passing to the scene. Other cars began beeping at them as they ran through the streets, legally, chasing an illegal runner.

Beeps were made at Antonio and Jay as they sped through as well. Voight and Olinsky went around another way. They had the choice to help the victims, but they needed to catch the jackass that did this. Other responders were close to the scene.

The criminal was fast. He made a sudden turn, into a side road with a few cars on it.

Antonio and Jay were farther behind because of the cars flooding the streets, but they could always be more productive in these situations, so they found a way around.

Atwater and Ruzek had already turned the corner of the street. And once the detectives in the car were about to turn there, another detective looking car was beginning to move forward from the street.

Then, all unexpected hell broke, when impact was suddenly felt through the car, on Jay's side. The car continued to drive for a moment, pushing the detective's car, since it happened so sudden that the other driver didn't even see.

But, as Jay looked to his side and out of the slowly shattering window, during the impact on his side, he was in even more shock and awe, as he realized…

It was Erin Lindsay.
