A victim of torture executioner on the video:
Frumkin Alexei Lvovich, born 03/28/1973
Residence address (registration):
Makiyivka (Donetsk suburb) city,
Str. (Verkhnyaa), Nagornaya 47

Date of disappearance: 10/24/2014

Here in this list (database of residents of Ukraine) has it:
http://nomer-org.net/allukraina/lastName_ФРУМКИН_pagenumber_0.html

Judging by the photos from his profile (and information from multiple databases) house belongs to his parents.
He lived in it, along with his old parents, and he has never been married.
There is information that his father died October 27, 2004: http://familyface.com/homo/pr/view/id/1068479
Interesting fact: The grandfather of the victim was tortured and killed by Communists (1937), which he supported, just like his grandson:
http://ok.ru/profile/538680486128/album/435126934256/441574458864

House on the map (center) :
https://yandex.ua/maps/-/CVHAEU7c

Judging by the fact that on all his photos he wears only 1-2 pairs of pants, the family (as the maximum) has average income.
They look like a modest family.

Taking into account the fact that he is alone on all of the photos (except a few photos with dogs and one photo with mother) -
he isn't too sociable man, he preferred to chat and flirt on the network.

1. Based on the profile of the Odnoklasniki (social network), his education - Donetsk technical school of industrial automation.
The profile also has a sorting by category of friends, a group of friends "colleagues" (at work):
https://ok.ru/profile/515816076874/friends?st.category=9&st._aid=FriendFriend_ViewColleague
There are nine profiles.
Two of those are hidden.
Six of them don't contain any valuable ​​or additional information, besides these people are refugees, who had changed their professions.
But one profile is good catch - it gives a certain idea of ​​human occupation - an employee of a major confectionery factory. (There are at least two in Donetsk).
https://ok.ru/profile/537622825254/pphotos/812897396518
https://archive.is/Unza4
These two observations suggest that the victim (probably) Engineer / Electrical / electronic equipment factory debugger at the candy factory.

2. In this commentary his refugee-friend (colleague) asks the victim "Why are you not fighting?"
Frumkin Alexei's reply was "I'm a pacifist".
https://ok.ru/profile/515816076874/pphotos/567480030538

3. His favorite video list (on social network) contains a video about dangers and horrors of addiction.
It's seems unlikely that a person who "involved in the drug traffic" could like this kind of videos and be afraid by this.
https://ok.ru/profile/515816076874/video/liked - the 6th top-down

5. The executioner in his profile (Vkontakte social network), and in an Graham Phillips interview justified himself by the "fact" that the victim had already been in prison for a crime earlier. (see p.9)
But in the "Ukraine unified state register of court decisions" no information about the victim - at least in the interval 2006-2016.
It is easy to check.
http://reyestr.court.gov.ua/
But... maybe it's true (partially) - In comments to the victim's profile, there is mention that he was in a kind of court (2013):
https://m.ok.ru/dk?st.cmd=friendMediaStatusComments&st.mtdt=STATUS&st.edit=off&st.rpl=off&st.topicId=550693274442&st.friendId=515816076874&_prevCmd=friendStatuses&tkn=5888#lst - Maybe it's just a friend joke or a local mem.

6. The victim - a Jew by both parents.
And he took it with great pride, and adored "Egyptian" themes - collected on this subject painting, wallpaper, the parable of King Solomon, was interested in his family tree.
Even his tattoo on his right arm (probably) this is an attempt to portray the ring (seal) Solomon.
It is possible that for the Nazi executioner pride of her nationality of the victim had a motive for murder.

7.
He is still listed in the missing persons databases.
There, you can see (text written by his relatives), some of the details:
http://naidy.org.ua/?p=3717
http://poisk.derzhava.today/propavshie/1219/show
Circumstances of disappearance: It is known that Alexei and the several others were taken by "Cossacks" to Zhdanovka, Donetsk Oblast on 10.24.2014. Then they were taken to Donetsk, where they were kept in the prosecutor's office. A few days later everyone was released, except for Alexei. According to the people released, it is known that he was beaten up badly, but he was still alive. There hasn't been any information about him since then. His relatives called to the People Search Service of DPR and it was clear that they knew something about him. But they either didn't say anything and dropped calls or said that he had been murdered. His relatives went to the prosecutor's office where the victim had been kept but it was said that there had never been such a person there.

8.
The executioner didn't hesitate to write texts about the schizophrenic sadistic pervert tortures:
