"In my world, there is no such thing as a control problem. There is controlled... and there is dead."
Born in Dolgoprudnyy, Russia, Arseny was thought to be a lifelong criminal, at some unknown point spending twenty-three years in four remote prisons in Perm, gaining a number of tattoos during his time there. In 1960, Arseny married a woman named Katya Fulenko, who died two years later, though not before giving birth to a son, Lyov. Due to becoming a member of the Russian mob, which didn't allow its members to have families, Arseny could not acknowledge Lyov's existence. At some point, Arseny legally immigrated to America, and set up shop in Baltimore, Maryland. In 2006, Lyov went rogue, committing a number of mutilation kidnappings. Arseny always reluctantly paid them, unable to admit he was not in control of the situation, or even that he had a son.
Honor Among ThievesEdit
In the episode, Arseny first appears to offer help to Natalya Chernus, breaking her father out from Lyov's hands. But, since she is actually allied with Lyov, she refuses, making Arseny look like the villain. He later pays the ransom despite what Natalya says. Arseny is visited at his "headquarters" by the BAU. Gideon attempts to get information about Lyov's abduction ring, but Arseny informs him that FBI interference is unnecessary, saying, "We take care of our own troubles." Meanwhile, at the abductors' hideout, Lyov attempts to kill Mr. Chernus, but Arseny's men arrive and kill Lyov and Natalya, dumping their dismembered and bagged bodies from a bridge.
Aseny had his mobsters kill his son and Natalya by shooting them and then ordered their bodies to be dismembered, the body parts put in bags, and dumped off of a bridge. It is assumed that he had other people killed by his mobsters under his orders.
