CLAY CENTER, Nebraska (AP) — A truck driver facing manslaughter charges in connection to a fatal crash in Clay County has reached a plea deal with prosecutors.

53-year-old Kenneth Johnson pleaded no contest Wednesday to two counts of manslaughter. A plea deal dropped a third count of manslaughter and a habitual criminal charge.

Authorities say Johnson was driving on Highway 14 in August when his semitrailer stuck a sport utility vehicle near U.S. Highway 6. Three people were killed: 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.
