The high school students, 14 and 15 years old at the time, allegedly attempted to exhort money from their classmate. When he refused to give it to them, they got angry and pushed him into the river.
The three boys and one girl initially claimed the boy had jumped by himself into the river.
“The river’s depth was about 3 meters (9’10″) and also had a strong current,” a police spokesperson said. “Because of these circumstances it was easy to predict that he could lose his life.”
The devastated parents and grandmother said, “We thought something was wrong from the beginning. Why would he jump into the river with his clothes on?”
