John Cleary (left), who was one of the injured students on May 4, 1970, shakes hands with author Thomas Grace during a multi-author book signing at the University Book Store on Wednesday, May 4, 2016. Cleary said he finally started enjoying coming back to campus because it’s an opportunity to connect with other wounded students. At right is Akron-area artist Chuck Ayers, who was a student at Kent State and witnessed some of the events of May 4.
