Detectives are investigating…after a semi-truck driver had a medical event, causing him to crash into two other big rigs. The DeKalb County Sheriff’s Department says the crash happened when a 41-year-old driver from Michigan was turning into the parking lot of the SDI complex in the 4500 block of County Round 59 in Butler. The driver told police he started to feel sick and may have blacked out due to a medical event. Reports indicate he continued westbound through the parking lot, hitting the front end of another parked truck before crashing into a second semi. The trucks were reportedly so badly damaged they were listed as a “total loss”. The Michigan man and the person inside the first semi he crashed into were taken to a hospital for treatment.
