WASHINGTON – More than four years after the deadliest mass shooting in modern U.S. history, the horrors of that day on the Virginia Tech campus are about to be relived in court.

An administrative judge is to begin hearing testimony Wednesday on whether the school should pay $55,000 in fines in connection to the 2007 shooting rampage on its campus that left 33 dead, including the shooter.

University officials and families of the victims are among those expected to testify.

The Department of Education says Virginia Tech was too slow in notifying students, faculty and staff of the safety threat on April 16, 2007. It says the school violated the law by waiting more than two hours after two students were fatally shot in a dorm before sending out a warning by e-mail. By that time, student gunman Seung-Hui Cho was chaining closed doors to a classroom building where he killed 30 more people and then himself. The department also says the e-mail was too vague because it mentioned only a “shooting incident” but did not say anyone had died.

Specifically, the university faces charges of failure to issue a timely warning and failure to follow its own procedures for providing notification.

The university says it acted appropriately in how it notified the campus that day and has exercised its right to an appeals hearing. It says that it followed standard protocols in place on campuses then and that the department is holding it to a higher standard than was in place at the time.

At the time the e-mail was sent, the university has argued, it was believed that the two students were shot in an isolated domestic incident and that the shooter was no longer on the campus. The school also contends it had planned a news conference to discuss the dorm shootings until the later shootings intervened.

The hearing before an Education Department administrative judge, Ernest C. Canellos, is expected to last two or three days. Canellos is not expected to issue a ruling until after the hearing.
