Authorities say winter weather may have been a factor in a Sunday afternoon crash that killed three Fort Dodge residents. State troopers say 28-year-old Michael Reed, his passengers 24-year-old Andrea Reed and three-year-old Isabelle Reed, died in the two-vehicle crash on Iowa Highway 17 near Boone.

The Reeds were headed north on the snow-and-ice-covered road, lost control and slid into the path of a van driven by Michelle Koch of Maryland. Koch was taken to a Boone County hospital. She and a passenger, Brittany Kramer of Clive, were treated and released.
