STORM LAKE — The Buena Vista County Sheriff’s office has released more information about a fatal accident on Storm Lake.

The two people who died when a car broke through the iced-over lake late Sunday afternoon are identified as 40-year old Zackary Newlon of Anthon and his 8-year old son.

Two of Newlon’s other children, a 9-year-old girl and a 5-year-old girl, were airlifted to a Sioux Falls hospital. There’s no word on their condition.

Investigators say it remains unclear why Newlon drove the vehicle onto the frozen lake.
