Kansas Attorney General Derek Schmidt said in a written release Wednesday that 45-year-old Steven Johnson,  pleaded guilty Monday in Geary County District Court to one count of second-degree murder and two counts of involuntary manslaughter while driving under the influence.

Investigators say Johnson was driving a large box truck that crossed the interstate median on Nov. 15, 2016, hitting a car head-on. The crash killed 26-year-old Jessica Michelle Thompson, 6-year-old Jaydon Allan Thompson and 5-year-old Leah Michelle Thompson.

Johnson is set to be sentenced on June 1.
