Authorities have released 911 calls from the scene of Wisconsin's worst-ever highway pileup.
Andrew Schefelker of Oshkosh was killed in Sunday's 131-vehicle pileup on Interstate 41 near Neenah.
Seventy-one others were injured in the chain-reaction crash that happened in the Neenah area amid whiteout conditions during a windy, snowy day.
The Winnebago County Sheriff's Office says the "vast majority" of the vehicles are destroyed.
Schefelker was a middle school/high school science teacher in the Iola-Scandinavia School District.
