STOCKTON, Ill. (WTVO) — On Saturday evening shortly before 5:00 p.m., Daviess County Sheriff’s deputies were called to Illinois Rt. 78 North about a quarter-mile north of Townsend Road for a report of a motorcycle accident.

When crews arrived they found 49-year-old Terry L. Cilley of Elroy, Wisconsin with his juvenile son. Officials say Cilley was riding his motorcycle with his son in a sidecar traveling south on Rt. 78.

Cilley drifted to the right side of the roadway and lost control of the bike. He struck a ditch and overturned, ejecting both him and his son from the motorcycle.

According to investigators, Cilley refused all medical treatment. The accident is still under investigation.
