(CNN) -- The university mental health files of Seung-Hui Cho, the man who went on a shooting rampage at Virginia Tech in 2007, were recently discovered, Virginia Gov. Tim Kaine said Wednesday.
Seung-Hui Cho killed 32 students and faculty members on April 16, 2007, then killed himself.
They will be released to the public as soon as possible, he added.
Cho, who was a 23-year-old senior at the time of the shooting, was known to have undergone counseling at the university, but his files had never been located, Kaine said at a news conference.
The files were recovered from the home of a former university employee who had left the counseling center months before the shooting, Kaine said.
"We think it is imperative that the file be made public as quickly as possible," he said.
Officials were searching for the files in preparation for a civil lawsuit against the university, formally known as Virginia Polytechnic Institute and State University.
Cho killed 32 students and faculty members on April 16, 2007, before killing himself as police closed in.
