Jindo, South Korea (CNN) -- The high school vice principal who was rescued from the sunken South Korean ferry was found hanging from a tree, police said Friday.
Kang Min Kyu, 52, was on board the ferry along with more than 300 students from Ansan Danwon High School. He was among the first survivors to be rescued.
Police said he apparently hanged himself with a belt from a tree near a gymnasium in Jindo, where distraught relatives of missing passengers have been camping out.
It's the latest tragic turn after the ferry's sinking, which remains unexplained.
