As Virginia Tech officials met this weekend with the family members of people killed and injured in the April 2007 mass shootings, a report in the Richmond Times-Dispatch raises new questions about the chronology of some events on the morning of the attack.

Members of the Virginia Tech Policy Group, a panel of campus officials who played roles in responding to the crisis, spoke with families of the deceased today and met yesterday with people who were injured during the massacre. The meetings, both of which were closed to reporters, were among the terms of a settlement that the university reached this past summer with families of the students and employees shot by Seung-Hui Cho, a gunman who killed 32 people before taking his own life. Many victims and family members have said they believe the university should have done more to warn the campus after the first two shootings, in a dormitory, were discovered. About 2½ hours later, Mr. Cho killed 30 more people in a classroom building.

Virginia Tech may have been slower to ascertain the whereabouts of an initial “person of interest” in the first two shootings than university officials had previously said, according to records obtained by the Times-Dispatch. After the early-morning shootings, the campus police identified a possible suspect and determined that he was not on the campus. (That student was later cleared of any involvement in the massacre.)

The police interview that led to that identification, however, apparently took place later than was previously reported. University officials told a state investigative panel last year that the campus police began that interview at 7:30 a.m., and that Virginia Tech officials were told the student was off campus by 8:10 a.m.

Earlier this month, Virginia Tech’s police chief, Wendell Flinchum, told families of the deceased that there was no mention of a possible suspect at 8:10 a.m. because the interview leading to that person did not start until 8:16 a.m. Mr. Flinchum’s comments — which the Times-Dispatch obtained through Freedom of Information Act requests — suggest that Virginia Tech officials may not have known about the person of interest until 9:25 a.m., just one minute before the university issued its first notice to students and staff members that there had been a shooting on the campus. That notification was issued 10 minutes after Mr. Cho began his rampage in Norris Hall.

“To know that this time line has been so off for so long, we feel that we’ve been misled,” Michael Pohle, whose son Michael was killed in Norris Hall, told the Times-Dispatch. “This just calls anything we have been told by them into question.” —Brock Read
