"It's night now. Let's go to the hotel and get some rest." Emily finally said. They had gone through loads of similar cases and titbits to find Mark and Dalton Berns, and Maggie Brett. Kayla and Mae were so far useless, because there was only so much a CSI and ME could do without a crime scene and a body.

Kayla had taken a warm shower to neutralise the effects the cold temperature had had on her body, and was now in her bathrobe, updating her Tumblr blog, crazedbibliophileandcinephile. At that time, her cell beeped.

You have 1 new message.

Jack Garrett: We have a body and a crime scene. Meet us in the hotel lobby. ASAP.

You: OMW.

Mark Berns' dead body was found in a dilapidated bungalow which was now cordoned off. Mae and Kayla were the ones going over everything in the empty room with only the cold body of Mark Berns. "I can't tell the COD now. But I would guess some kind of poison, because there aren't any signs of physical damage. I'll have to take him to the lab though." Mae said. She looked around the room to check if she had missed anything, when she gasped. On one of the walls was written the word: DESERTER in blood. Kayla pulled out her phone and took several photographs of the word from several different angles, and then they went out to meet with the rest of the team. "Mr. Petrov, Do you have a crime lab where we can work?" Mae asked their liaison Nikolai, who was still groggy and annoyed at being woken up at 3am. "Yes .I will send one of my men to transport you and the body to the lab first thing in the morning."

"Looks like our UnSub had a SUV." Kayla said from outside the yellow taped area. Everyone looked at her with confused expressions. "You measured the depth and area of the tire marks, Pressure is force per unit area?" Reid asked her. "Average mass of an SUV. Give or take maybe, 100-150 kgs depending on the person sitting inside. Also, our UnSub is approximately 5'10." "How do you know his height?" Morgan asked. "As Arthur Conan Doyle pointed out so kindly in 'A study in scarlet', 'when a man writes on a wall, instinct leads him to write just above eye level." Kayla answered distracted.

"Утром собирайте своих офицеров. Мы готовы предоставить профиль." Emily told Nikolai Petrov.

Translation: Gather your officers in the morning. We are ready to give a profile.

Ilya Fedunov had arrived to the station early today. The Americans were working on their case, and his senior, Nikolai Petrov had told him and his mates that the Feds would be giving a profile today. The entire station was sitting and the old-ish man, who introduced himself as David Rossi started giving the profile.

"The UnSub, or Unknown Subject in this case, is mostly a nationalist. He is hunting those whose ancestors left the country during the war times, which leads us to believe that someone close to him too has left the country and he is now facing abandonment issues. We do not need to go to psychiatric centers because this kind of person isn't likely to share his problems. He is independent, will not go to anyone for help."

"Anyone strikes to your mind?" the Blonde woman asked them. A murmur ran through the crowd. Ilya reluctantly raised his hand. "Yes?" "I-I'm not sure, but could it be someone from Дезертир?"

The two brunettes looked confused. "Deserter?" the one called Emily Prentiss asked. "Yes, yes," Nikolai told her, "Deserter is a support group of sorts, for those who lost their relatives due to such reasons in the WWII."

Mae came in then. "I have determined the time of death as between midnight and 1am, and the COD, which I found surprising, is Diphosgene." Reid spoke up. "Diphosgene was used as a chemical weapon in the world war. If our UnSub was deserted in the world war, it's no surprise that he might use Diphosgene. It relates to his history."

Jack's phone rang. "Monty. Garcia. What do you have for us?" "Yeah. So we were digging into Mark Berns' life, and you, are not going to believe us when we say this to you", Garcia spoke fast with the background noise of her keyboard like white noise to both the teams' ears, "We thought Jasper and Jeff McBride were aliases, but Jasper was caught up in some internet scam last year, when a black hat used his photo and the name of Mark Berns for a shelf baby." "We also found out that Jasper's relatives still live in Russia. He might just have wanted to visit them." Monty continued.

"Garcia," JJ told her, "Send us everything you have on a group called Дезертир"

"That Intel is on your way. PG out."

A/N: Forgive me if any of my information or profile is wrong; I am a writer not a profiler; That 'support group' doesn't exist; or maybe it does, but this one is my imagination. Also, if any disrespect is caused, I sincerely apologise.
