A renewed effort in underway at Ohio State University to catch the arsonist who killed five college students in April. University officials say that case still weighs on the minds of campus-area residents...and OSU wants to do its parts to help solve the case. The university has come up with a poster that will start going up on-campus and in near-by neighborhoods. It implores anyone who has any information about that fire on East 17th Avenue, to contact authorities. University officials say, now that six months have passed, and that deadly arson remains unsolved, they want to make sure returning students report every bit if possible information…and want new OSU students to be on the lookout as well.
