Two files proving this were reportedly found in a handphone of Jong Ho Song, a senior official of Chongwadae, on Oct. 29.

The files were dated October 16 and 18, which means they were created before the hot media reports that confidential documents of Chongwadae were stored in a computer of Choe.

The documents reportedly contain methods for Choe to get rid of the network of investigation by the prosecution and evade legal punishment.

Commenting on this, south Korean media accused Park and Chongwadae of trying to cover up the scandals.
