Mourners visit the makeshift memorial in front of Burruss Hall at Virginia Tech on Saturday. Since the shootings, the memorial has grown daily. Also on Saturday, an eBay spokesman said Seung Hui Cho had purchased ammunition clips from the online auction site. Investigators were searching through Cho’s cell phone records and had sought a warrant for Virginia Tech e-mail records to perhaps establish a connection between Cho and his first victim, Emily Hilscher.
