An 18-year-old eastern Iowa woman and her two-year-old son were both killed this morning in an accident in Iowa County.

The Iowa County Sheriff's Department reports that Bethany Clark of Belle Plaine was traveling east on Highway 212, about five miles west of Marengo when her vehicle left the road at around 7 a.m.

Authorities believe Clark lost control due to frost on the road and, after leaving the roadway, her car hit a creek embankment before catching fire.

Clark and her son Roran both died at the scene.

Our condolences to the family during this incredibly difficult time.
