(ST. ELMO, IL) — A 58-year-old O’Fallon man was killed Tuesday morning when the semi-truck he was driving overturned on Interstate 70 in Fayette County. David Foltz was driving on I-70 when the semi he was driving just east of St. Elmo ran onto the right shoulder of the interstate. He brought the truck back onto the roadway, but overcorrected and his truck went into the median and overturned onto the driver’s side. The St. Elmo, Altamont and Brownstown fire departments responded to the scene and extricated Foltz from the semi. The Fayette County Sheriff’s Office, ISP, and Altamont police were on scene.
