The following is a story from the Associated Press.
The Highway Patrol says the two crashes happened about 10 minutes apart Friday night near Eckelson.
Authorities say each brother was driving an ATV to a farm. Forty-three-year-old Kyle Foster of Tucson, Arizona, was the first to roll his four-wheeler into a slough. He died at the scene.
His 47-year-old brother, Jeremie Foster of Fargo, made it to the farm and then began to retrace his route to find his brother. He lost control, rolling into a ditch, and died on the way to a hospital.
Authorities say neither brother was wearing a helmet and alcohol was a factor in both wrecks.
