Mercer County Coroner Ron McNall has released the identity of the person killed in the straight truck rollover accident south of Aledo. 32 year old Shawn Thompson of Dahinda was pronounced dead at the scene Monday afternoon. Illinois State Police say he was traveling north-bound on Illinois Route 94 when he went off the right side of the roadway. He apparently then over-corrected, forcing the truck to roll onto its top. A stretch of the highway was shut down for about six-hours before opening Monday night at around 8 p.m.
