In a preview of a long-anticipated report on the Virginia Tech shootings, Gov. Timothy M. Kaine told reporters today that the commission he appointed to investigate the tragedy found “a lot of instances” in which the gunman’s disturbing behavior beforehand was not reported to officials — at Virginia Tech or elsewhere — who could have done something to prevent the massacre. The 300-page report is scheduled to be released on Thursday, just over a week after the university issued its own report on the shootings.

Governor Kaine, a Democrat, said he had reviewed the report, and according to The Roanoke Times said it would be “thorough and fair” and would answer many questions about the April 16 shootings, which took the lives of 32 students and professors, as well as the gunman, Seung-Hui Cho.

“I’m troubled that a student who had talked about Columbine at an earlier point in his life, that that information was unknown to anybody on the Tech campus,” Mr. Kaine said, according to the Associated Press, referring to Mr. Cho’s apparent fascination with a 1999 massacre at Columbine High School, in Colorado.

The Virginian-Pilot reported that the governor said the report’s findings do not justify calls for the resignation of top officials at Virginia Tech, including its president, Charles W. Steger, and its police chief, Wendell R. Flinchum. Mr. Kaine described the report as focused on “recommendations for improvement,” some of which could be carried out soon, without the need for legislative action.

The report is expected to deal specifically with the issues of law enforcement, campus security, treating mental-health problems, and respecting privacy laws. —Andrew Mytelka
