A Randolph man died in a single-vehicle accident Thursday in rural Clay County that also injured four family members.

Kevin L. Dettmer, 51, died on the scene of the accident on 30th Road near Valley View Road, about 8 miles north of Green.

According to the Kansas Highway Patrol, Dettmer was driving east on 30th Road in a 2006 Dodge Durango at 9:15 p.m. when he swerved to avoid a cardboard box. He overcorrected, and the vehicle struck a bridge pillar and came to rest on the south shoulder under the bridge.

His wife, Kyra, and their three children, 11, 8 and 5, suffered serious injuries. Responders transported Kyra and the 11 year old to St. Francis Hospital in Wichita and the 8 year old and 5 year old to Clay County Hospital.

No one in the SUV was wearing a seatbelt, according to the crash report.
