Our sister station WCSJ reports that the person who died in a three-vehicle crash in Morris on Sunday was an off duty Cook County Sheriff’s Officer who was assisting a broken down vehicle.

According to the Cook County Sheriff's Office, 50 year-old Ronald Prohaska is the deceased. The sheriff's office said in a statement that Prohaska started at the sheriff’s office as a correctional officer in 1994 and joined sheriff’s police in August of 2004. He most recently served in the fugitive warrants unit.

The crash occurred on Route 47 over the Illinois River Bridge in Morris around 4:00 p.m. on Sunday.

The Morris Police Department said a vehicle broke down in the southbound lanes of Route 47 and another vehicle assisted at the scene. That’s when another vehicle rear-ended the assisting vehicle causing a chain reaction.

Two of the vehicles were engulfed in flames upon arrival by first responders. At least two people were transported to Morris Hospital and police officials say Prohaska, who was assisting the broken down vehicle, was airlifted to Good Samaritan Hospital where he died from his injuries.

The Illinois River Bridge was closed until 8:20 p.m. on Sunday night so first responders could reconstruct the accident and clean up the area. The reconstruction was conducted by the Illinois State Police.

Morris Police said the driver of the vehicle, who caused the incident, was cited for electronic communication and failing to reduce speed to avoid an accident.

No other details have been released regarding the accident which remains under investigation.
