The Frog Boys (Korean: 개구리소년, Gaegurisonyeon) were a group of five young boys who disappeared in Daegu, North Gyeongsang Province, South Korea, on March 26, 1991.
Woo Cheol-won, Jo Ho-yeon, Kim Young-gyu, Park Chan-in and Kim Jong-sik, aged between 9 and 13 years old, disappeared after searching for salamander eggs in the western outskirts of Daegu on a public holiday. Their disappearance received widespread attention and caused a national media frenzy, and South Korean President Roh Tae-woo ordered a massive manhunt by the police and military to find them.
On September 26, 2002, the remains of the boys were discovered near where they vanished, with some showing signs of blunt-force trauma. The investigation has been inconclusive and theories abound regarding the circumstances of their deaths. The case remains unsolved.
