The Illinois State Police are asking the public for help in finding a hit-and-run semi driver accused of fleeing the scene of a fatal crash on Interstate 70 near Troy.
The deceased driver was identified as Jacob Dey, 20, of Brighton, according to Madison County Coroner Steve Nonn. An autopsy determined a preliminary cause of death as blunt trauma to the head.
Funeral arrangements for Dey are pending at Targhetta and Wooldridge Funeral Home in Brighton.
Westbound Interstate 70 was closed for seven hours Wednesday morning in the aftermath of the accident, while debris was cleaned up and accident investigators reconstructed the crash, according to Illinois State Police spokesman Calvin Dye Jr.
Dye said the accident happened at 1:50 a.m. when the driver of a Chevrolet Impala swerved to the right for unknown reasons and then over-corrected to the left. The maneuver caused the car, driven by a 20-year-old man, to come to a stop sideways on the interstate.
A semi truck clipped the front of the Impala, causing it to spin several times, Dye said. When the car came to a stop, a second semi hit the car in its passenger side door, Dye said.
The impact of the second strike killed the driver, who was the only person in the vehicle, and the car ended up in the ditch on the right side of the interstate.
The crash caused the second semi to roll on its side and land in a ditch, spilling a full load of corn. According to police reports, the truck driver was not injured.
"The driver of the first semi did not stop and has not been located," Dye said, adding that the truck likely has significant damage to its front from the collision.
Anyone with information about the accident or the hit-and-run semi is asked to call the Illinois State Police at 618-346-3990.
In an unrelated crash, one lane of southbound Interstate 55-70 was closed early Wednesday morning near Collinsville after a pair of trucks collided.
The crash happened just before 5 a.m., according to police reports. One of the trucks was a tractor-trailer and the other was a smaller truck pulling an enclosed trailer.
The smaller truck ran off the road into the center median, rolled over and ended up facing the opposite direction while its trailer was on the left shoulder of the interstate.
Police said no one was seriously injured in the second accident.
