Mac and Jo are standing at the counter in local bar, talking with victim's friend, Jon Constanza. Jon is in late 20's, about 5'10 tall, average weight, with short blonde hair and blue eyes. He is wearing brown T-shirt and black pants.

"He... he never quite talked with me about his... problems", Jon says. "I guess he didn't want me to worry. I don't know did he have any problems or enemies. I mean... I still can't believe that he is dead!"

"What's the last time you saw him?", Mac asks.

"Two days ago. He stoped for a drink aftet work. He seemed fine."

"Where were you yesterday between four and six pm?", Jo asks him.

"I was working here from one pm till nine pm. Then I drove back home."

"Can anybody confirm this?", Mac asks.

"Well... I don't remember all the guests and this security cameras are fake... I'll look up for my card", he says, walks away, and soonly returns with his employee card and puts it on the counter, in front of Mac and Jo. They look at it and see that he is telling the truth.

"Thank you for your time", Mac says.-Here is our card, so you can call us if you remember something", he says, takes card from right pocket of his pants, and puts it on the counter in front of Jon.

"Sure", Jon nods.

Mac and Jo walk in the morgue towards the autopsy table where Malcolm's body is. They wear white latex gloves over their palms. Sid is standing near by, still wearing white latex gloves, his lab coat, and his eyeglasses. He is holding evidence bag with swab inside it in his hand. Two other evidence bags are on small grey metak desk near the table: one with bloody bullet inside, other with bloody blue fibers inside.

"The cause of death is single gunshot wound to the heart", Sid explains. "I found some brown residue in his nose, like dirt or a sand. I found same traces in his hair. I tooked a sample of it", he says, handling evidence bag to Mac, who takes it.

"We'll give that to Lindsay", he says. "Did you found the bullet?"

"Yes. It's right here", he says, handling evidence bag to Jo, who tooks it.-I also tooked samples of blue fibers from the wound.

Jo nods.

Danny is in the crime lab, siting at his desk, wearing white latex gloves and white lab coat. Theodore Jenkin's gun is on his desk, and also evidence bag with bloody bullet, ear protection and comparison macroscope. He takes bullet from evidence bag, puts it under macroscope and briefly examines it. He takes Theodore Jenkin's gun, and briefly examines gun barrel. It looks pretty clean. Then he puts ear protection over his ears, stands up, walks in front of the bucket full of water. He walks few feets away from it, checks is the gun loaded, points it towards the bucket, and fires one shot in it. Then he puts gun back on his desk, takes off ear protection amd puts it on the desk too, tooks bullet from the bucket, sits back at his desk, puts it under macroscope, and compares it with bullet found in victim. Then he scans abrasions on the bullet in computer and starts running them through IBIS. They don't mach. Mac walks in Danny's office, towards Danny's desk.

"Hi, Mac", Danny says, noticing him. "I examined the bullet. It's .45 calibar. I examined barrel of Theodore Jenkin's gun. Gun was last time fired about three years ago. Just in case, I compared bullet fired from Theodore's gun with bullet found in victim. They don't much. I'm runing bullet through IBIS right now."

Soonly, computer beeps. Match is found.

"So...", Danny says, reading informations from computer screen. "Gun was used in murder commited nine years ago. Victim was twenty-two year old Melissa Morales, found shoot to death in her apartment. Case is still unsolved and they never found the gun."

"Any suspects?"

"Yes, her ex-boyfriend, Neil Johnston, twenty-eight at the time. She broke up with him four months prior to the murder. He didn't take it very well. Due to lack of evidence, he was never charged for her murder, but he was sentenced on two years in prison for marijuana posession. He did his time in same prison Malcolm did. Now he works as janitor in local High school. He lives ten miles away from Malcolm's house."

#

Mac and Jo are talking with Neil, in back yard of a High school, while he is mowing the grass. Neil is thirty seven years old, about 6'2 tall, average weight, with short brown hair, brown beard and moustaches. He wears his janitor's uniform, brown working boots and white working gloves.

"I kinda assumed he will end up on that way", Neil says. "Most sex offenders do."

"What was the last time you saw him?", Mac asks.

"Month ago, while walking on the street. We just said Hello to each other and continued walking."

"Do you know did he had any enemies?"

"No. I served time in same prison as he and knew him, but I don't know much about him."

"Where were you yesterday between four and six pm?", Jo asks.

"I finished shift at three pm. I was in that casino ten miles away from there from four pm till seven pm. Why are you questioning me?"

"Same gun used to kill your ex girlfriend nine years ago was used to kill him", Mac says.

"I didn't kill her. You couldn't proove it nine years ago, you can't proove it now. And I definitely didn't kill him either."

Mac's phone rings. He tooks it from right pocket of his pants and answers.

"Hello?"

Sheldon is on the line.

"Mac, I examined shoe prints found on secondary crime scene. This is whole new brand of working boots, out on sail only for last week. Only few stores have them so far. 40 pairs are sold so far. And shoe prints found there are pretty small, size five. Only one person purchusaed that brand of boots size five so far, two days prior to murder. And person who purchusaed them paid with credit card. We have a name. Elaine Morgan, 32, married, mother of two."

#

Mac and Jo are talking with Elaine on her workplace: she is planting flowers in Central Park. She is average height and weight, Caucasian, with long black hair and blue eyes. Mac immediately notices her boots.

"We found your shoe prints on place where Malcolm Lake's body was found", Jo says. "You wear very distinctive boots, you know. Only you purchusaed them in size five."

Elaine glares at them.

"And also, by depth of shoe prints and scuff marks, it looks like you were draging something heavy in the ditch, left it there, and walked away", Jo explains.

Elaine stops with her work and tooks a deep breath.

"Explanation?", Jo asks.

"Yesterday, at about two pm, shortly before my shift was over, I decided to dump some junk in that ditch near runing path close to this location", Elaine says. "I had it in trunk of my car and I was too lazy to walk to the dumpster. I thought I heard somebody aproaching. I didn't want to loose my job. I dumped junk outside the ditch, on the path, run out the ditch, tooked junk and run away."

Elaine is wearing blue T-shirt, white jeans, her working boots and her gloves. She is draging big black trash back in the ditch, leaving deep shoe prints and scuff marks. She sees shadow aproaching and stops. She lifts the bag, dumps it outside the ditch, on path, runs out of ditch, tooks bag, and drags it away.

"There was no body there! I later dumped it in the dumpster. I think they tooked out trash this morning."

"Can you describe that person?", Mac asks.

"Unfortunately, no. I was gone before I could get a clear look on him. Or her."

"Where were you yesterday between four and six pm?", Mac asks.

"My shift was over at three pm. I drove back home, alone. And I was there, alone, till 7 pm, when my children came home. They were playing at their friends."

"And your husband?", Jo asks.

"He is on buisness trip for last week. He is coming back home tomorrow."

"Do you owe a gun?", Mac asks.

"No, and I never did. Neither did my husband. You can check. Can I get back to my work now, please?"

"Not till we took your boot prints and swab them", Jo says. "We also need to test you for GSR and took samples of dirt from this eria."

Lindsay is in her lab. She is wearing white latex gloves and white lab coat. Evidence bags are all over her desk. She takes burned shirt from evidence bag and examines it. She notices one unburned part, puts shirt on the desk and takes fiber samples from that part of shirt. She puts that fibers under comparison mycroscope, then puts fibers found inside victim's wound under it too, and compares them. They match. She tooks burned wallet from other evidence bag, tooks burned I.D. and drivers licence from it, and scans them under infra-red light. She manages to recover about eighty precent of both and conclude that those are Malcolm Lake's I.D. and drivers licence. Then she picks up photograph of bloody fingerprint found on door knob of Jon Gray's apartment. She scans it in computer and compares it with elimination samples. Soonly, computer beeps; match is found.

At that moment, Don walks towards her.

"Hi, Don!", she says, noticing him. "I managed to recover some usable fibers from burned shirt found in trash can and compare them with fibers found in gunshot wound on victim's body. They matched perfectly. Also, I managed to recover serial number from burned cellphone and link it with our victim. I am still tryng to recover some informations from SIM card, but it is so damaged that I doubt I will anything. I also managed to track down signal of GPS he had in his car. I sent Adam and Jamie to check it out."

"What about brown residue found in his nose and hair?", Don asks.

"I'm still working on it. But I found something interesting in John Gray's case."

"What?"

"I found bloody thumbprint on door knob. DNA analysis of blood is still in progress, but thumbprint matches to one found among elimination samples: thirty year old Howard Smith, owner of apartment which Jon Gray was renting."

#

Don is talking with Howard in interrogation room. Howard is Caucasian, tall and strong, with short dark hair and eyes. He is wearing white T-shirt, blue jeans and black sneakers. Photograph of his thumbprint is on the table next to him.

"Yes, I guess this is my thumbprint", Howard confirms. "So what?"

"So what? Your bloody thumbprint is found on door knob of the apartment in which man was bludgeoned to death, and you don't think that is... I don't know... suspicious?"

"Look, that's my blood."

Don glares at him.

"Look, I live... I lived next to that guy. That morning, about an hour before the murder, I cuted my palm while making breakfast.-While saying so, he shows his right palm, covered with white sterile gauze from inside.-I had no gauze to cover the wound. I ringed his doorbell, he opened, found sterile gauze and gave them to me. I said "Thank you" and left. Blood probably came on my thumb. I probably accidently touched door knob and left the bloody thumbprint. This is my blood, not his. Also, why would I kill him?"

"I don't know, you tell me. And you can also tell me this: where were you at the time of a murder?"

"In my apartment, alone. Can I go now?"

"You can't go anywhere till DNA analysis of that blood is over and compared with both your DNA and Jon's DNA. And if it doesn't match to your DNA, and if it does match to Jon's DNA, you can't go for about twenty years or so. And we will also need that gauze."

#

Jamie and Adam walk towards place where signal is located. This is lonely, dirty alley with big dumpster. Both Jamie and Adam wear white latex gloves over hands and white plastic shoe covers near shoe bottoms.

"I don't see car here", Jamie says while looking around.

"Me either...", Adam says, looking around, then walks closer to the dumpster and looks in it. He notices GPS in it, on top of the trash.

"But GPS is definitely here", he says. He puts brief case on the floor and opens it. He puts forensic tag on top of the trash in dumpster, next to GPS device, and photographs it. He puts photograph in briefcase. He notices tyre track in dust on the ground near by. He puts forensic tag next to it too, photographs it, and puts that photograph in brief case too. He takes evidence bag from brief case, puts GPS device in it, seals the bag and puts it in his forensic briefcase too. He notices chewing gum on the floor. He picks it up, takes another evidence bag from brief case, puts chewing gum in it, seals it, and puts it in brief case too. He takes a swab from brief case, swabs dust in which tyre track is with it (carefully so he wouldn't smudge the tyre track) and stores that swab like other evidences so far.

"That could be good source of DNA", he explains. Then he takes fingerprinting kit from his forensic briefcase. "We got lucky", he comments. "Most of the trash in other dumpsters in town are on junkyard by now."

"I'll powder down this dumpster for fingerprints", he explains. "I'll also probably need to search whole dumpster, maybe gun is in it."

"I'll search the eria, look up for witnesses or the car", Jamie informs him. "I will leave dirty job for you", she smiles.

Adam chuckles and nods. Jamie walks away, and Adam starts powdering dumpster for fingerprints.
