From Chicago Sun Times:

"Authorities were investigating whether the gunman who killed 32 people on the Virginia Tech campus in the deadliest shooting rampage in U.S. history was a Chinese man who arrived in the United States last year on a student visa.

The 24-year-old man arrived in San Francisco on United Airlines on Aug. 7 on a visa issued in Shanghai, the source said. Investigators have not linked him to any terrorist groups, the source said."
