The exact cause of death has not yet been confirmed, but it is thought to be most likely suicide at the moment as traces of butane gas has been found, as well as a will addressed to his family, a portion of which read, "I am sorry to my family."

Kim Jong Hak was previously investigated for embezzlement with the cast and the other staff of 'Faith' not receiving proper payment, and was forbidden to leave the country with the investigation going on. Those close to him believe these happenings took a toll on the PD's mental state.

Kim Jong Hak brought to life dramas like 'Eyes of Dawn', 'Sandglass', 'Daemang', 'The Legend', and 'Faith'. 

Our sincere condolences go out to his family and friends.
