A South Korean student who committed suicide by jumping from his 20th floor apartment landed on top of and killed another man walking home with his pregnant wife and son, a news report said Wednesday.

The 38-year-old local government employee was returning from work in the southern city of Gwangju on Tuesday when he was struck by the 25-year-old student, the Yonhap news agency said.

The man had been walking with his wife who was eight months pregnant and their five-year-old son.

Both men were taken to a nearby hospital but neither survived, Yonhap said.

The agency said police planned to charge the dead student with manslaughter in order to ease any insurance claim brought by the other man's family.
