The Ohio State Highway Patrol continues to investigate a five-vehicle crash that claimed one life, injured four people and shut down the westbound lanes of Interstate 76 in Jackson Township since shortly before 11 a.m. Thursday.

Troopers say a semi driven by Robert Brock of Saratoga Springs, Utah struck the rear of a stopped semi driven by Kevin Roberts of Fort Wayne, Indiana.

The impact forced Roberts’ semi into a stopped car driven by Mark Schaas of New Castle, Pennsylvania.

Schaas’ vehicle was then forced into a stopped semi driven by Steven Cole of Apple Creek, Ohio.

A van driven by Guy Garner of Paterson, New Jersey, was in the left lane and was struck by the cab which separated from the semi driven by Kevin Roberts. The semi driven by Robert Brock caught fire after this crash.

Killed at the scene was Mark Schaas. His passenger William Lawrence was trapped in the vehicle and had to be extricated. William was flown from the scene to St. Elizabeth’s Hospital in Youngstown, Ohio, with serious injuries.

Robert Brock was trapped in his cab which separated from his truck and was flown to St. Elizabeth’s Hospital with serious injuries.

Kevin Roberts was transported to St. Elizabeth’s Hospital from the scene with serious injuries.

Steven Cole was transported to St. Elizabeth’s Hospital with minor injuries.

Guy Garner was not injured.

Traffic in the area was backed up due to road construction on IR 76 westbound.

Interstate 76 westbound has been closed since the crash.

Traffic is being diverted on SR 46 in Austintown.

The Ohio Department of Transportation is rerouting traffic around the crash scene by sending cars and trucks along Route 46, to Mahoning Avenue, to route 534.

The Ohio State Highway Patrol said they don't suspect drugs or alcohol were the cause of the accident. They will be looking at the main driver's log book to see how long the driver had been on the road. 

A reconstruction team will be brought in to try and find out how fast the drivers were going prior to the accident. The speed limit in the area is 70 miles per hour. Although the area where the crash happened is currently a temporary construction zone, the speed limit had not been reduced. 

Ohio State Highway Patrol said they will be contacting the Mahoning County prosecutor's office to see if any charges will be pressed.
