The Indiana State Police Department is investigating a crash that leaves a pedestrian seriously hurt after being hit by a semi Saturday evening on the Indiana Toll Road in Steuben County. Troopers responded to the eastbound lanes of I-80, a few miles east of the Angola exit. Officers find the man lying in a grass median with a semi-tanker and disabled car along the shoulder in serious condition at this hour. The victim is identified as 22-year-old Jack Holdren of Williamsburg, Virginia. A preliminary investigation shows Holdren was changing a flat tire when his dog walked into the roadway. He ran out to get his dog when he was hit by the semi. Medics take Holdren to a hospital in Fort Wayne. The post-crash investigation by both state and local officials is on at this hour.
