WATCH: Officer Climbs Over Cars To Rescue Victim In 131-Vehicle Pile Up

Body cam shows the dramatic moment a police office climbs over a vehicle to rescue a victim trapped inside.

Authorities have identified a 30-year-old teacher as the person killed in what is now being called the largest traffic crash in Wisconsin history.

Winnebago County Sheriff John Matz on Monday identified Andrew Schefelker of Oshkosh as the victim of Sunday's 131-vehicle pileup on Interstate 41. Matz says Schefelker was a middle school/high school science teacher in the Iola-Scandinavia School District.

Seventy-one others were injured in the chain-reaction crash that happened in the Neenah area amid whiteout conditions. At the time of the crash, snow was blowing across I-41 and piling up on the median. The conditions were so bad that at one point, two deputies say they were standing 30 feet apart and couldn't see each other.

Within two hours of the crash, deputies had everyone either diverted off the interstate, into a warming centre, or at the hospital.

"After the crashing stopped happening, we exercised our mass casualty plan. EMS and hospitals practice this plan and it was put into place and it worked well," said Sheriff Matz.

The Sheriff's Office says the cars that were involved in the crash have been impounded. They have not released the cars yet because deputies still need to collect evidence from them.
