Kim Hae-sun

On October 25, 2000, the first victim was found by her best friend. Jung Hye-in, aged eleven, was found dead on a mountain about 150 meters away from the road on which she was last seen alive. A few days later, the autopsy confirmed that she had been strangled. Semen was found on the victim's body.

On July 11, 2000, the Jeonju District Court sentenced Kim Hae-sun to death after he was convicted of rape and murder. Kim immediately appealed to the Supreme Court, but on September 27, 2001, the appeal was dismissed.

He helped his father with farming, but did not know how to work properly due to mental illness and drinking alcohol from time to time. As a child, Kim Hae-sun was habitually hit by his father, being stripped of his clothes and hit with a belt. At one point, he was expelled from the house. Kim also said that he had never visited a public bath due to his wounds. As stress relief, he tortured cats and dogs. He began to have extremely violent tendencies, such as sickening his neighbor's cattle and killing them. At the age of 16, he was sent to a family court for a stolen item. At the age of 24, he was sentenced to one year in prison and two years probation for a violent crime. At the age of 26, he was sentenced to four years in prison and three years probation for raping a female pen pal. At the age of 27, he went to Busan and worked as a restaurant employee at the Yeonang fishing boats, where he learned how to use seamen's knots and was able to work with knives. Then, he gathered money working as a tea house employee in Busan before returning to his hometown in July 2000, three months before the murders.

Kim Hae-sun (born on May 6, 1969 in North Jeolla Province, Gochang County) was a South Korean serial killer and rapist who killed three minors in 2000. He also attempted to rape and kill another high school student, but the attempt was halted.
