The DeKalb County Sheriff’s police and Coroner’s Office are investigating the death of a 21-year-old Geneva man killed Saturday night in a one-vehicle crash.

Police said Matthew J. Kenney was traveling southbound on Illinois Route 23, south of Preserve Road, when his 2000 Ford Explorer crossed the opposite lane, went into a ditch and struck a tree. The vehicle continued for about 140 feet before coming to a rest.

Kenney, who was not wearing a seatbelt, was thrown from the vehicle. He was taken to Kishwaukee Community Hospital where he was pronounced dead.

Police were unable to say whether alcohol was involved in the crash.

Sources who knew Kenney said he was on his way home from NIU.
