The shooting rampage, the deadliest in modern US history, left 33 dead, including the gunman, Cho Seung-hui.
 
A senior in the university's English department, Cho had been living in the United States since 1992.
 
According to South Korean media reports Cho's family had struggled to make ends meet and when Cho was eight years old they decided to emigrate to the US in search of a better life.
 
The family had lived in a rented basement apartment in a Seoul suburb, usually the cheapest unit in an apartment building, reports said.
 
Gun ban
 
Although South Korea remains technically at war with neighbouring North Korea its citizens are banned from privately owning guns.
 
 
In 1982 South Korea was the scene of one of the world's deadliest shooting sprees, when Woo Beom-gon, a police officer, killed 55 people and wounded 35 others in an eight-hour overnight rampage in the southeastern village of Euiryeong.
 
The shootings were apparently triggered after Woo quarrelled with his live-in girlfriend.
 
In 2005, a military conscript believed to be angered by taunts from senior officers killed eight fellow soldiers, throwing a grenade into a barracks where his comrades were sleeping and firing a hail of bullets.
