Mac looked at him with his flashlight and he noticed the man was dead. "Call for the M.E and I'll call for another investigator to come and process the scene with me."

"Okay," Officer Johns said as he radioed for the M.E.

Mac called Lindsay to get his kit at the crime lab and come process the scene with him, then Detective Flack showed up.

"Mac! Are you alright?"

"I'm fine. I was doing some work when I heard shots fired then I tried to find the gunman," Mac said while the officers secured the crime scene.

"I wonder how long he's been dead for?" They looked at the body.

"I don't know, but it appears to be quite sometime. I'm going to go back in and get dressed, I need to look decent."

"I'll be here, checking to see if anyone heard the shots and trying not to let the guy's stink bother me." Don and other officers went door to door to see if anyone saw or heard anything. Most people did not.

A while later, Lindsay showed up in the truck with her camera and kit, as well as Mac's. She walked to the alley and Mac resumed looking around with his flashlight.

"Here you go, Mac."

"Thanks." He took the camera and his kit and as they started taking pictures.

"How long ago was he found?"

"I heard gun shots about an hour ago then found him after searching for sometime. He does look like he's been dead for awhile."

"Did you sleep at all?"

"Not really. I think I got 5 hours sleep. What do you think of the vic's injuries?"

"Looks like he'd been tied up and tortured. Do we have a name on this guy?" Lindsay looked at his wrists and noticed some rope marks and bruises.

"No wallet, no ID. He was shot at close range but I think he's been shot several times before and tonight was the last time he'd been shot."

"This killer is creepy. Why shoot the guy a second time if you've already shot him before?" They looked at each other quizzically.

"I don't know."

"Is it me or does this guy stink?"

"No, he does stink."

After a few hours, the scene was cleared and they went back to the lab to process the evidence. They processed what little evidence there was then a few hours later Sid had called them to the M.E.'s office.

"What do you have for us, Sid?" Mac asked as Lindsay stood next to him.

"Well, I've already taken his finger prints and sent them up to Adam to process when he gets in. But this guy has been through the ringer time after time."

"It sure looks like he went through a lot," Lindsay said.

Sid showed them the CAT scan of the man's head. "See here, he was hit with a blunt object multiple times. The killer seems to have let each wound heal a bit before hitting him again," Sid said.

"Any idea what the object was?" Lindsay asked.

"No, but I'm thinking something flat, like a crowbar or the edge of a 2 X 4," Sid suggested.

"What about these ligature marks?" Mac asked.

"Some kind of rope or tie, but again, it appears they were used, then removed until the injuries healed, then he was restrained again," Sid said then continued, "Also, it looks like his wrists were bent back then were broken, and the same happened to his fingers."

"Poor guy," Lindsay said.

"I've also sent his clothes up to check for trace and here is the bullet," Sid said as he gave Mac the petri dish with the bullet in it. He continued, "The clothes should be there now but I'd wear a mask if I were you, they stink." Sid rubbed his nose.

"It does appear he went quite sometime without taking a shower, and after being dead for who knows how long..." Mac said.

They both left the office and went back to the lab as they walked quietly. Lindsay hoped that Mac wasn't going to leave her with the stinky clothes by herself when they noticed Jo walking with Sheldon.

"Morning. We thought you were at a crime scene," Jo said.

"We were this morning but just came back from seeing Sid," Mac said then continued. "Where are you off to?"

"Uh... we have to check on a location of a suspect, can't tell you more, sorry Mac," Jo said. Sheldon smiled as they both left.

"What was that all about?" Lindsay asked.

"Oh come on, Danny didn't tell you?"

"Are we talking about the case that we can't talk to you about?"

"Yes, I think."

"Oh, I thought it was about another case."

"No. It's just hard not to be in the loop," Mac said.

"I'm going to go to the ballistics room and test fire some guns." Lindsay took the petri dish from Mac's hand as she walked away and he looked at her, then chuckled.

Mac went in the trace lab, took out the pants from the bag then put on his mask since the pants smelled bad. He used the microscope to look over any evidence the killer left then processed it then a few minutes later Lindsay came in.

"Did you finish with the testing of the bullets?" Mac asked as Lindsay put her mask on then her gloves and got the shirt that was in the bag.

"No. Adam is using the ballistics lab so I figured I'd help you with this processing."

"He's here at 8:30 in the morning?"

"Yeah. He's working on the Turner shooting."

"Well, I've already sent some small traces that were on the victim's pants up to trace." Lindsay continued to look over the shirt with the magnifier.

"Got a hair here." She put the hair in a small envelope.

"Hopefully we can get DNA off it. Also, I think we will have the clothes hermetically sealed after we process it."

Meanwhile at an apartment complex-

They had gotten prints off the burned car and they belonged to Robert Neilson. Sheldon had gotten a new address for him.

"I hope this guy is there," Sheldon said.

"I hope so too," Jo said.

Don approached and knocked as the SWAT officers were ready. "NYPD! Robert Neilson, open up." He looked at the officer with the battering ram and nodded as he moved slightly out of the way.

The officer swung the ram and the door busted open. The detectives and officers went inside and noticed the room was empty.

"Damn! Missed him again!" Jo said as she looked around.

"This is borderline ridiculous," Don said when a man and his daughter approached.

"Excuse me, what are you doing in my house?" the man asked as his young daughter stood behind him.

"Please tell me we don't have the wrong house," Sheldon said annoyed.

"I don't know. Do you know where you are at?" the man asked.

Jo showed him the warrant.

"He doesn't live here and I don't know who he is," the man said as he gave Don the warrant back.

"Must be a fake address," Don said as he sighed then said to the man, "Sorry."

The man nodded then the police left for the precinct and the lab.

At the lab-

Adam walked out of the ballistics room and headed back to his work station when smelled a horrid stench. He turned and saw Mac and Lindsay walking towards him. He leaned forward and started to sniff.

"Oh!" Adam shouted quietly.

Mac and Lindsay looked at him confused.
