LIVINGSTON COUNTY - Icy conditions could be to blame for the death of a 22-year-old Pontiac woman.
The crash happened in rural Livingston County in the Rooks Creek Township.
Authorities say a passerby found Rebecca Koltveit unresponsive.
Koltveit's pick-up truck apparently left the road after crossing an icy bridge.
It seems she lost control of the truck, went through a fence, and landed against a tree.
The crash is under investigation.
An autopsy is pending.
