A woman and small boy were killed when the vehicle they were in rolled over on Interstate 35.

The Kansas Highway Patrol says the accident happened Tuesday evening four miles north of Waverly in Coffey County.

The patrol says a vehicle driven by 26-year-old Krystal Smith of New Strawn went onto a median in the interstate and Smith overcorrected, causing the SUV to roll several times.

Smith and Cory Sheppard, also of New Strawn, died in the accident. The patrol said Cory was about 4 but his exact age was not immediately known.

A 9-year-old and 6-year-old in the vehicle were injured.

It was not immediately clear how the people were related.
