Alison was in the middle of collecting evidence off one of the VIC bodies when Mac walked up to her.

"What do we got, Alison." She sealed the envelope.

"Murder-suicide but not the way we normally find it. The shooter didn't commit suicide." Mac looked over her shoulder then gestured for her to get closer. She stood up, walking over to him.

"Why's Danny doing the interview? I thought Flack was on this case." Alison flinched slightly, looking down at her feet.

"He didn't show up. I couldn't get a hold of him. So I called Danny." She looked up at him, bracing for his next words. "What should we do?"

"I'll call his C.O., have him put him down for a day off." Mac shook his head. Turning his attention back to the case. "Walk me through it." He pointed at the victims.

"Right, our shooting VIC is Kenneth Grant. He's a hedge fund player, and he hand, his partners, were celebrating the recession with a little party. When Bob over there decided to put one right in his forehead." Alison pointed at a man in cuffs being watched by an officer. Apparently, he wasn't satisfied with Kenneth's hedging. He's just about to take out another partner when."

"The jumper saves the day. But he died on impact. But considering we are under a bridge, that was probably the idea." Mac looked around the boat. "Hawkes is looking at the place where he jumped. Can you finish up down here?"

"Yeah, I'll clear things up here and see if Danny needs anything."

"Good, let me know if you find anything. I have to look into somethings."

Greg sat across from Messer, looking over a bank robbery report. Stella had been working it, but something personal came up, and she handed it off to the two of them.

"So you think that this was an inside job. Who out of the 6 employees do you think it was. Gloria. She seemed shifty during her interview." Greg said, looking at the notes Stella had made.

"No, she's not strong enough to pull the plant in front of the camera. And she's not the right body size for the shooter." Messer titled his head.

"But Loren, the assistant manager, is the right height."

"Yeah, but she has a bad back."

"I don't know; maybe they're all are involved." Greg's phone went off, and he stood up.

"It's Mac follow that thinking that might explain the sticks that were in the vault." Greg stepped out of Messer's office, answering the phone.

"Sanders."

"Flack didn't show at Alison's crime scene." Greg placed his forearm on the wall resting his forehead on it.

"I tried calling him, but he hasn't answered."

"That's what I was afraid of. Listen, Greg, I need you to run over to his apartment and see if he's there." Greg straightened.

"Sure thing, anything you need."

"If you have a spare key, use it. And if he's sleeping one-off, throw him the shower and call me."

"You got it." Greg took a deep breath before heading back over to Messer.

"Hey Greg, I think this might actually be all of them." He looked and stopped. "Mac needs you to do something, doesn't he." Greg grabbed his coat.

"Fraid so I'll be back when I'm finished and can work late tonight." Messer waved him off.

"I'll follow this lead. Don't forget your cane. Your limping." Greg ignored him. He needed to find Flack and get him sorted out before it was too late.

Alison stood next to Syd, looking at the body scan.

"Your jumper broke every bone in his body except for two of them." Alison shook her head.

"Jumping from a bridge and landing on a boat will do that to you."

"And yet." Alison winced.

"Don't say that I was supposed to help Erin clean out her storage unit." Syd pointed at the chest of the victim.

"Sorry, But he was shot in the chest, and it lodged in this center area."

"Is that what killed him." Syd took his glasses off.

"That's the thing. Since he jumped, it's hard to see where he was hit. If it hit an artery, he would have bled out but considering everything. I'm ruling that the jump killed him before the bullet got a chance."

"It's an odd place to shoot yourself, and we didn't find any stippling pattern on the clothes. Meaning the gun had to be fired at least three feet away."

"You better call Danny and let him know that his murder was staged as a suicide." Syd paused, tilting his head.

"What somethings bothering you?" She asked him. Syd took a deep breath.

"He normally hangs his victims but could this be the compass killer." Alison's eyes shot to the body.

"No, we didn't find any of the signatures. I mean, the Compass killer always leaves a note of remorse and a compass with each body." Alison ran her hand through her hair.

"Alright, I'll talk to Danny. He has more experience with this case than I do." Syd flinched slightly. The compass killed had started before she was back at the lab 3 months ago. From the look on Syd's face, he had forgotten. Alison smiled at him, trying to remove the guilt that filled his eyes. She hated that look. "Can you get me the bullet as soon a possible?" Syd relaxed at her change in subject.

"Did you find the gun?"

"No, but the killer dropped the body off the bridge why on a gun."

Greg walked up to Flack's apartment, using his fist to knock on the door.

"Flack, it's Sanders, open up." He waited a minute, listening for any sound before pulling out his key. Taking a deep breath, he unlocked to door into the apartment. The sight that greeted him as sadly a familiar one to him pulling his phone out he called Mac.

"Sanders, what did you find." Greg walked over to the couch by the TV.

"There's food everywhere, and it doesn't look like he's paying his bills." He walked into the kitchen, counting the bottles of alcohol he could easily see. "Definitely been drinking. Mac, I hate to say this, but this looks like what my apartment started to look like when Alison was taken. The only thing that kept me from getting this bad was the hope that we would find her. Mac, he doesn't have that with Angel." Mac let out a low sigh.

"Greg, go to the front closet top shelf." Greg's stomach turned into a rock as he walked to the door. Opening the door, he relaxed at the sight of Flack's gun.

"No, Mac, it's here."

"Good. At least he's smart enough to leave his gun at home."

"What do you want me to do next?"

"Hit his local stops if he's not there, track down his sister. Maybe she knows where he is."

"Alright, I'll keep you up to date." Greg hung his phone up, looking around the apartment. This could have been him. Now he had to make sure that the darkness didn't take his friend.

Alison walked over to Danny and Baez's desk, holding up a folder.

"Hey Kid, what'd you bring us today from your lab." Alison smiled, taking Danny's cup of coffee handing over the folder. "I was drinking that."

"I know, and now I am." Baez shook her head.

"This has to be big if you're coming all the way down here." Alison leaned against Danny's desk.

"We had Hawkes search under the bridge for the potential gun that I told you about." She explained to Baez while Danny read. "And we found a compass instead." Danny looked up at that.

"SO you think that it the Compass Killer."

"Yeah, I know that he normally hangs his victims, but the compass matches his signature. The needle is permanently facing east. He glued it just like the others." Baez stood looking at the file where the pictures were.

"Why change his MO."

"I don't think he had a choice," Danny said. "We were getting too close. Did he leave a note?" Alison reached over, flipping to the last page.

"Yeah, Mac saw him watching from the bridge while we were on the water. By the time we got to the spot, he was gone leaving just the note. "It says, "I should have stayed awake. I'm sorry" handwriting matched the sample we have on file." the officers cleared the area still no sign of him." Danny shut the folder.

"That's our guy."

Greg walked up to Mac, who was walking down the hall.

"I check all his normal locations and even some of his not so normal ones." Mac slowed his walk noticing to Greg frustrations the amount he was limping.

"And I'm guessing you walked the entire time without your cane." Greg ignored the comment, handing over a piece of paper with an address on it.

"What's this."

"I triangulated his locations using his cell phone. It's not a nice area, Mac. I was going to go check it out but wanted to let you know first." Mac stuck the paper in his pocket.

"No, you've done enough. I'll take it from here." Anger shot, thought Greg.

"I can do this, Mac."

"I know, but you have already done enough. Now go help Messer out with the Bank robbery, and I'll see if I can find Flack." Greg looked down at his feet. It was probably for the best, but that didn't make it any easier.

"Fine, but let me know if you need anything." Mac patted his shoulder.

"Sure thing."

Alison took pictures of the small hospital room while Danny looked over the file they provided.

"I can't believe that a man with schizophrenia was able to just walk out of this place," Alison said looked over the drawings on the walls.

"Yeah, the time line matches with the killing, and his picture looks like the sketch." Alison pulled one of the pictures off the wall.

"This looks like our first victim." Danny looked around the room and pointed at a drawing of a woman stuck to the window.

"That looks like our second VIC." Alison pointed at the drawing next to that.

"And there's our third VIC."

"Al, I think we just ID our compass killer." Danny looked at the desk in front of him. "Hold up, hold up." He picked up a sketchbook so Alison could see it. She had taken a picture of it early but hadn't really looked at it. "Now, who's this." Danny flipped the page. "To my beautiful Calliope." Alison tilted her head.

"I was looking over the evidence from the other vic's, and the compass on the first VIC had the initials C.E. engraved in it."

"This guy's name is Eckhart, maybe his wife."

"Hopefully, she can tell us where he is." Danny scanned the paper.

"No, it's not gonna be possible. According to this, she was murdered two years ago."

Greg sat in the lab looking over the notes that Messer had main. The DNA on the sticks matched each of the employees. The shortest stack was the one that matched the employee that was shot in the arm. There was a knock on the door. Looking up, he smiled at Alison.

"Hey hun, how was your day." Alison walked over to the chair next to his pulling her feet up.

"Long I feel like I could sleep for a week. And Eckhart got away. So the Compass killer is still out there." Greg reached over, rubbing her back. She leaned into it, closing her eyes.

"I just have to finish this report for the DA, then we can head home." Alison rubbed the back of her neck.

"Actually, you can drop me off at Erin's. I still have to help her out with that storage container." Greg shook his head.

"That's right. How about I go to Jamie's to see if he needs any help fixing Joe's old car while you help Erin. Whoever is done first saves the other." Alison rolled her eyes.

"You don't even know if Jamie is working on the car tonight." Greg raised an eyebrow.

"Ally, he's always working on that car. Besides, he asked me to pick him up a part earlier today. While I was out of the lab." Alison rolled her eyes. Mac walks into the office.

"Thanks for your help today, Greg." Greg glanced over at Alison then back at Mac.

"Did everything get sorted out?"

"Yes, it's all taken care of. Thanks again. See you two tomorrow." Alison spun her chair, so she was facing Greg.

"What was that about?" Greg looked around the lab, making sure it was empty.

"He had me look for Flack since he didn't show up at your crime scene. But it looks like it's all sorted out." He signed the file and shut it, putting it in the stack next to him. "Now, let's get going before Erin and Jamie finish all the work before we get there." Greg stood up, holding out his hand helping Alison to her feet.

"Wouldn't want that." Greg kissed her.

"No, we wouldn't want that."
