Ryan is sitting at the table in the interrogation room. Mac and Jo are also sitting at the table, opposite to him. Roy is tall and thin, with short black hair and black eyes. He is wearing white T-shirt, black pants and brown boots.

"Ryan", Mac exclaims, "man was murdered this morning. Jon Harper, eighty five. We found your hair in his house."

After short silence, Ryan says: "It isn't my."

"DNA prooves that it is", Jo explains.

"Maybe it's a mistake or something."

"And what about a jacket and gloves that we found in dumpster near your house?", Mac asks. "There were burn marks on them. And traces of smoke. We also found those traces in trunk of your car. And your DNA is inside the gloves and on the jacket. Also, gloves match to glove print found on back doors of a suspect's home."

Ryan remains silent, looking down at the floor.

"OK", Mac calmy exclaims, "you don't need to talk. We have enough evidence to keep you in custody." He and Jo stand up and start walking toward the door. When they are about to leave, Roy yells after them: "Wait!"

They smirk and sit back at the table.

"OK, I was there... but I didn't kill anynody."

"What happened?", Jo asks.

Ryan takes a deep breath before answering.

"Look... I was planning to rob the place. I arrives there... uhm... it was close to six am. I had my gloves over my hands and everything. I decided to break in thighs the back doors, they appeared unlocked-and they were. I smelleds a smoke, but didn't think it's something important... at first. When I walked in, I saw that something is burning in the living room. I thought that maybe someone is on fire, I ran there, took of my jacket and mask and dumped it over a fire. That put off the fire, but when I listed jacket and mask, I only saw some ashes and... a human foot. Then I heard a car so I ran away. I didn't do anything else, I swear!"

Mac and Jo just briefly glare at him, obviously thinking is what he said true.

"Can I go now?"

"You just admitted a burglary, so no, you can't go", Jo answers. "And at this point, you are still a murder suspect."

Don and Jamie are interrogating Kimmy's parents, Michael and Emily, both in late 40's. Parents are sitting on a couch in living room, and Don and Jamie are standing in front of them in living room, holding notebooks and pens in their hands and occasionaly writing notes.

"We... we didn't see Kimmy in five years", Michael says. "We had a disagreement... she was living on her own since the age of eighteen, attending college, studying Physics... she had fallen behind one year and we refused to talk with her... we didn't hear from her since."

Emily puts her hand over her mouth, trying not to cry. Michael pulls her closer, biting his lower lip.

"Do you know did she had any enemies? Did anyone want to hurt her?", Jamie asks.

"No, we don't", Michael says. "Like I said, we didn't hear from her in half a decade."

Don and Jamie walk toward the front doors of a room in cheap motel, number ten. They are wearing latex gloves over hands and plastic shoe covers over shoe bottoms. Jamie is holding a key in her hand.

"Hotel manager confirmed that's the room where Kimmy was living for Thr last two months", Jamie says, unlocking the door. "She was always paying on time, in cash."

"He also said that he didn't see her since last night and that she didn't check out."

They walk in the room and start looking around.

"There are no signs of a strugle", Don notices. "No traces of blood. Nothing seems out of order."

"But the weird thing is", Jamie remembers, "that Kimmy didn't have keys in her posetion when her body was discovered." She looks up at the ceiling. "So, who took it... and why?"

Don lifts the mattress and looks under it. He notices nothing suspicious.

"If anyone was here, he was carefull and he put everything back on the spot", he concludes, and puts the mattress down.

"Security is bad. Lock on the back doors is broken for over a year and there are no securirty cameras, anyonaback sneak in."

"Yes... we better send Danny and Lindsay here to dust the room for prints. By the way, did you found out anything useful about Steve Jules?"

"Yes. His only family is sister who lives in LA, and he works as a grave digger. He has a job on a local cemetery. Yet, today, cemetery is closed due to some construction works. He had a day off. So... why was he wearing an uniform and gloves? Where was he heading?"

Sheldon is sitting at a desk in his office, wearing latex gloves and lab coat. On the desk near his computer are evidence bags full of evidences colected from crime scene. Near the box is a fingerprint lifting kit.

First, he takes an evidence bag with a hammer inside, opens it and takes out a hammer, putting it on the desk, on a clean piece of paper. He picks up a fingerprint brush and applyies the fingerprint powder on it's handle. He fonda few usable fingerprints, so he lifts them with a tape and scans them in a computer, comparijgng them with an elimination samples. All fingerprints match to Michael. Then he does the same with a knife. Fingerprints found on it match to two people: Michael and Stephanie. Then he scans a photograph of a bloody palm print found in room and scans it in a computer, then compares it with the elimination samples. That palm print, too, matches to Michael. He also compares knife and hammer with stabbing and fracture wounds casts made by Sid. They match.

At that point, Mac walks in his office.

"Oh, Mac", Sheldon says, noticing him. "I found several usable fingerprints on the hammer and the knife. All usable fingerprints on a hammer match to Michael, and all the fingerprints that I recovered on the knife handle match to Stephanie and Michael. Bloody palm print found in room also matches to Michael. I compare hammer and knife with the casts of the wounds that Sid made. They match perfectly."

"What about DNA?"

"Blood sample taken from a bloody palm print found in room matches to her. Analysis of other samples isn't over yet, but I can tell you right away that things aren't looking good for Michael."

Mac and Adam are walking down the hallway while talking. Adam is wearing lab coat and latex gloves. He is also holding a piece of paper in his hands.

"Only Natalie's DNA is on the watch", Adam says. "I also analysed the skin cells found under her fingernails and found two DNA profiles, both female. One belongs to a victim herself, and other one belongs to an unidentifeid woman. DNA profiles are different, but similar", he says while handling Mac the paper. Mac takes it and takes a look at it, then, almost immediately, widenes his eyes.

"Mother?"

Don and Jamie are sitting at the table in interrogation room. Twenty nine years old Ramona Beness is also sitting at that table, opposite to them. She is Hispanic, about 5'8 tall, average weight, with long black hair and black eyes. She is wearing black T-shirt, blue jeans and pink sneakers.

"Ramona", Don exclaims. "Man named Steve Jules was found killed in his car this morning, with an axe. We found an ear ring in his car, on the floor, with your DNA on it."

Ramona widens her eyes in surprise.

"You have a sample of my DNA?"

"You were arrested because of the shoplifting five years ago, don't you remember?", Jamie asks.

"Oh... yes."

"And his phone records proove that you left him some pretty nasty messages days prior to his death. So... would you like to explain that?"

Ramona sighs, then answers: "We broke up few weeks ago, after eight months of dating, and week ago, I see him leaving a club with another girl! So, I waited for him to leave, then confrinted him when he approached his car. It got pretty heated... my ear ring probably fell off on his clothes and then roldowmn the car floor.""

"What was the bar called?", Don asks.

"I don't remember."

"Can you describe a girl?"

"I don't know, it was dark and I saw her from a distance! Talk, slim, Caucasian... blonde hair... I don't remember anythihg other than that."

"Where were you today at about seven am?"

"Home, alone. Getting ready for work."

"When did you arrive at your workplace?"

"At about eight am. Can I go now?"

"What do you think?", Don asks her smugly, and Ramona's face fells.

Mac is back inside the Natalie Doyle's house, in the living room, talking with her mother, Jane, who is sitting on a couch, while he is standing in front of her.

"Ms. Doyle... we found your DNA under your daughter's fingernails."

Jane widens her eyes.

"My DNA?".

"Please, roll up your sleaves."

Jane does so. Mac sees scratches on her right wrist.

"These scratches look fresh", he exclaims. "How did you get them."

Jane takes a deep breath before answering.

"It... it's not what you think."

She slids he hands down her face before continuing.

"We got into a fight the night before. Over a grades. She grabbed my hand for a moment... that's probably how it happened."

Mac glares at her, still suspicious.

"Why didn't you mention that to us?"

"I didn't think it was important for investigation. Also, I was ashamed. Especially in front of my husband. I got in a fight yesterday with my daughter and now..."

She covers her mouth with her hand, trying not to cry.

"I would never hurt her. You need to believe me."

Mac's Ipod rings. He picks it up from right pocket of his pants and answers.

"Hallo?"

Jo is on the other side of a line.

"Mac? We may have an ID on the teenage boy found in that abandoned house."
