UPDATE: 5:45 p.m.

One person is dead and many people were injured following a pileup Sunday on I-41 that involved about 100 vehicles, officials said.

Emergency crews responded to a initial report of a 40-vehicle pileup in the southbound lanes of I-41 at Highway G in Neenah about 11:10 a.m. Reports from police scanner radio traffic referred to the pileup as a “mass casualty incident,” according to the Milwaukee Journal Sentinel.

As of 2:20 p.m. Sunday, the Wisconsin Department of Transportation is estimating that I-41 will remain closed for at least 10 hours. In a Twitter post, the DOT confirmed the fatality and said that all drivers and passengers have been removed from the crash site.

Winnebago County Sheriff’s Department Chief Deputy Todd Christopherson said Sunday during a news conference that whiteout conditions were to blame for the crash, which could take weeks to investigate.
