Authorities in Wisconsin have released 911 calls and police video that show the chaos of a deadly, 131-car pileup during whiteout conditions.

Sunday�s chain-reaction crash on southbound Interstate 41 near Neenah, about 100 miles (161 kilometers) northwest of Milwaukee, killed a 30-year-old school teacher and injured 71 others.

One woman called 911 to report she was just in an accident. She said she �can�t see anything� and �everybody�s just crashing into us.� She later screams and says, �My car�s just shaking. I don�t feel safe in the car.�

Photos released by the Winnebago County Sheriff�s Office show crumpled cars, pickups and semis smashed into one another on the snowy highway. In body cam video, a responding deputy crawls over the wreckage and yells to a trapped motorist to hold on.

Sheriff John Matz says it�s believed to be the largest traffic crash in Wisconsin history.
