A Texas man has been arrested in a head-on Kansas crash that killed a mother and her 5-year-old daughter and critically injured the woman’s son.

The 42-year-old Houston driver is jailed in Geary County on $250,000 bond on suspicion of two counts of involuntary manslaughter while driving under the influence and two other counts. No formal charges have been filed.

Kansas Highway Trooper Ben Gardner says 26-year-old Jessica Michelle Thompson, of Junction City, had taken her children out of school Tuesday for a medical appointment. They were returning when a large box truck crossed the median on Interstate 70 and crashed into the family’s vehicle in Geary County.

The crash killed Thompson and her daughter, Leah Michelle Thompson. Her 6-year-old son was flown to a Wichita hospital in critical condition.
