MORAINE, Ohio — A four-car crash on an Ohio interstate killed an inmate and injured others who were assigned to clean up debris on the highway, authorities said.

The Ohio State Highway Patrol said the crash on I-75 south of the University of Dayton exit happened shortly after 11 a.m. Monday.

The truck struck a sheriff’s office transport van that crossed the roadway, struck a concrete barrier and then was hit by two other vehicles, Lt. Jeffrey Freeman said, according to the Dayton Daily News. One inmate was pronounced dead at the scene, officials said.

Montgomery County Sheriff Rob Strack said in a statement that the three inmates and a sheriff’s deputy were treated at local hospitals and released. The two unharmed inmates were returned to the jail “where they received mental health counseling,” the statement said.

The name of the inmate who died in the crash has not been released pending notification of next of kin. The Dayton Highway Patrol is investigating the crash.
