[5] In July 2018, Roh was under investigation into accusations that he had accepted ₩50 million from an aide to an influential blogger[13] known as "Druking"[2] while at the center of an opinion-rigging scandal.

Roh was a cello player from his elementary school days, and often dreamed of a society where every citizen could pick up a musical instrument.

His death occurred during the course of the special prosecutor's investigations into the illegal political funds of Druking, the main perpetrator of the South Korean opinion-rigging scandal.

[15][13] Roh's will, addressing the Justice Party and its membership, admitted receiving ₩40 million (approximately US$35,300) from Druking's organization but denied any form of favoritism in exchange for the campaign contribution.

[16] According to Political Fund Act which he supported, it is still illegal and guilty because the amount of money he has received already exceeds the legitimate scope.
