Busan Adult Toy Store Murder Case: Who is the Real Culprit?

SBS "I Want to Know That" will air on the 7th, delving into the shocking murder mystery that occurred at an adult toy store in Busan.

On the night of February 13, 2004, the truth behind the brutal murder of Lee Jeong-sook (pseudonym), who had been running an adult toy store in Chungmu-dong, Busan, for six years, will be investigated.

Lee Jeong-sook was an ordinary woman who had been working tirelessly in a challenging industry to support her daughter.

On the day of the incident, at 9:38 PM on February 13, 2004, she was on the phone with a friend when she abruptly said, "A customer has arrived," marking her last words. After not hearing from her, a worried acquaintance checked the store after midnight, only to find Lee Jeong-sook already discovered as a cold corpse.

Two Notorious Serial Killers: Shocking Confessions

Two infamous serial killers are being considered as suspects in this shocking case.

The first is Yoo Young-chul, who brutally murdered 20 victims, including the elderly and women offering massage services, between 2003 and 2004.

Yoo Young-chul, who has a history of killing adult toy sellers, is suspected of committing another murder in Busan during the break period of his crimes in February 2004.

Another suspect is Lee Doo-hong (pseudonym), who was the actual model for the movie "The Drug King." He has a history of strangling a nightclub waitress located in the same building as the adult toy store, and he even wrote a confession letter claiming he was the culprit in the adult toy store murder case.

The crime scene was found disheveled, with the lights still on and blood splattered around. The victim was discovered in a corner of the store with her lower clothing removed, suspected to have died from strangulation after being beaten multiple times in the face. This gruesome murder went unnoticed, receiving only a brief mention in the newspapers at the time. Lee Doo-hong, who died in prison in 2018, ultimately did not reveal the full story of his crimes.

"I Want to Know That" will track down the identity of the real culprit who took Lee Jeong-sook’s life by using a peculiar glasses lens left at the scene as a clue, investigating who the last customer was that visited the adult toy store that night.
