Police said on Wednesday that they can find no link between Cho Seung-Hui and his first alleged victims in last week's shooting rampage.
Emily Hilscher (pictured) and dormitory resident assistant Ryan Clark, 22, were the first of 32 people slain on the Blacksburg campus April 16. Witnesses claim to have seen gunman Cho Seung-Hui waiting outside Hilscher's dorm at about 7 a.m. that day, State Police Superintendent Steve Flaherty said in a news conference."There's no motive that we're convinced of or can support with evidence," Flaherty said.
Police gave new details of Cho's shooting spree.
In a space of less than ten minutes Cho fired more than 170 bullets and killed 30 people, Virginia Tech Police Chief Wendell Flinchum claims.
Nearby were Cho's 9mm and .22-caliber pistols, Flinchum said, as well as unused ammunition. Evidence gathered in the past week shows Cho may have practiced at local shooting ranges.
