The Kidnapper

Voice of a Murderer is the titular antagonist in 2007 South Korean true crime psychological thriller Voice of a Murderer. Voice of a Murderer is based on an actual kidnapping case which occurred in 1991 in which the unidentified suspect sadistically taunted the child's parents for 44 days demanding ransom. The antagonist in the movie is just as sadistic if not more and portrayal is overall faithful to the tragic story.

Voice of a Murderer is portrayed by Kang Dong-won.

History

Voice of a Murderer kidnaps 9-year-old Hang sang-woo from his apartment's playground late at night and almost immediately makes the ransom demand to his parents - 100 Grand, no cops or their child dies. When the understandably upset and overtly concerned mother secretly reports it to police when her husband goes to the ransom drop, he unwittingly blows the assigned undercover officer's cover and the kidnapper

changes the ransom drop to another day.

Similar circumstances, rotten luck on the police's part, and perhaps cruel fate makes the parents seeing their son again more unlikely as days turn into weeks and the kidnapper shows no emotion execept for sadistic glee and condescension with sarcastic politeness. The kidnapper seems to know the parents and police every move while the police fail to comfort the parents or find clues to the kidnapper's identity other than his chilling voice. At one point he kidnaps the detective in the father's trunk and beats him up to mock the police and parents.
