His body was found in a car which had been parked near a road of Solsong-myon, Richon City, Kyonggi Province on December 13.

He in his suicide note claimed that he had nothing to do with the case and he was falsely accused of being principally accountable for the leakage of the document.

It is reported that he usually hinted at his fellow policeman that Chongwadae was trying to bring a charge against him.

Media persons held that this meant there were pressure and appeasement from Chongwadae.

Infuriated by this case, the bereaved family side claimed he died because of the authorities' attempt to bring the charge against him, adding the political camp is entirely to blame for his suicide.
