The investigation panel had sought Cho 's medical records for several weeks , but due to privacy laws , Virginia Tech was prohibited from releasing them without permission from Cho 's family , even after his death . The panel had considered using subpoenas to obtain his records . On June 12 , 2007 , Cho 's family released his medical records to the panel , although the panel said that the records were not enough . The panel obtained additional information by court order . Like the perpetrators of both the Columbine and Jokela school massacres , Cho was prescribed the antidepressant drug Prozac prior to his rampage , a substance suspected by Peter Breggin and David Healy of leading to suicidal behaviors . It is not known if Cho ever complied in filling or taking this prescription ; or if he had taken and then discontinued the prescribed medication . The toxicology test from the official autopsy later showed that neither psychiatric nor any kind of illegal drugs were in his system during the time of the shooting
