The Kane County Coroner's office has released the name of the pedestrian killed Wednesday after being hit by a semitrailer truck in Elgin.
Derek Blaha, 31, of Elgin, died shortly after the 10 a.m. crash on Big Timber Road near the intersection of Hillcrest Drive. An autopsy conducted Wednesday showed internal injuries as the preliminary reason for Blaha's death, according to a statement from the coroner's office.
An official ruling in the cause of death is pending toxicology tests, which will be conducted in a forensic laboratory, according to the coroner's office. Results could take up to eight weeks.
Police said the man was walking north across Big Timber Road and was hit by the trailer portion of the truck, which was traveling east. There are no sidewalks or crosswalks in that area.
The truck's driver, a 47-year-old man from Carol Stream, was not injured, according to Elgin Police Lt. Dan O'Shea.
Members of the coroner's office and the Elgin Police Department continue to investigate Blaha's death.
