The Virginia Tech killer may have rehearsed his rampage 2 days before the massacre of 32 people on April 16, police investigators said today. One witness reported spotted a suspicious-looking hooded male near doors inside the academic building where the shootings took place on April 14, the Richmond Times-Dispatch reports; another witness saw chains on the door that same day.
Investigators also revealed that bloody clothing found in his room conclusively links 23-year-old Seung-Hui Cho to the two murders in a dormitory 2 hours before the shooting spree in Norris Hall. They continue to search for a link between the victims and Cho, who police now say obeyed a 2005 court order by contacting multiple mental-health facilities.
