CLAY CENTER, Neb. (AP) — A truck driver has pleaded not guilty to manslaughter charges in the crash deaths of three family members in Clay County.

Online court records say 53-year-old Kenneth Johnson on Wednesday pleaded not guilty to three counts of manslaughter and one count of being a habitual criminal. His next scheduled court date is Nov. 12.

Authorities say that on Aug. 28 Johnson was driving south on Nebraska Highway 14 when his semitrailer stuck a sport utility vehicle where Highway 14 met U.S. Highway 6. Three people in the SUV were fatally injured: 53-year-old Gary Isom; his wife, 52-year-old Susan Isom; and their daughter, 26-year-old Tiffany Isom. The couple’s teenage son survived the collision.

The Isoms lived in Hastings.
