His name was Cho Seung-Hui, and he was American.

Cho Seung-Hui was not Chinese -- he was South Korean. They're about as much the same thing as Russian and Italian. More importantly, he was American; he'd lived in America since moving to Detroit at age 8, and had LPR (legal permanent resident) status for many years. In America, a legal permanent resident must be 18 before he can begin the naturalization process (in other words, before he can apply to become a citizen), and naturalization takes a long time. Cho Seung-Hui was 19. He was pretty close to being a citizen of this country.
