Ohio State University says a background check on a janitor who shot two supervisors didn't reveal a past criminal record.
Ohio State on Wednesday released a background check compiled last fall on Nathaniel Brown, who entered a maintenance shop Tuesday morning and fatally shot a supervisor, injured another and then killed himself.
Prison records say Brown had a criminal history that included serving about five years in prison on a charge of receiving stolen property. He was released in 1984.
Ohio State said it hired an outside vendor to conduct the background check. The report by OPENonline LLC said it found no criminal records on Brown.
