The Day After

The Virginia Tech student identified as the assailant in Monday's deadly gun rampage was a South Korean immigrant who had been in the United States since 1992 and who held a green card signifying his status as a legal permanent U.S. resident, federal officials said Tuesday.
Cho Seung-Hui, a 23-year-old English major, was listed with a home address in Centreville, Va., a suburb of Washington, D.C., not far from Dulles International Airport.

Despite identifying the killer, little else is known about him. University officials said he lived in a dormitory on the Virginia Tech campus, but could shed no light on a motive for the shooting spree that left 33 dead. "He was a loner, and we're having difficulty finding information about him," said Virginia Tech spokesman Larry Hincker.

A long note found in his dorm room reportedly said, "You caused me to do this." I'm not sure who "you" refers to.
