Markers installed in remembrance of students injured, killed at Kent State The new markers were installed earlier this year and help give perspective to where the wounded students were standing as well as the location of the Ohio National Guard troops who fired the shots. “They should have been installed a long time ago,” Jacobs said of the markers. “I love the fact that they're there and it shows who was killed and how far away they were from where the National Guard was.” While people came to campus to remember and reflect in person, the official commemoration of the 51st anniversary was held virtually, featuring talks by former students who were hit and injured by some of the 67 shots the Ohio National Guard fired off that afternoon.
