Authorities found the body of a missing Wisconsin graduate student Eliotte Heinz in the Mississippi River on Wednesday following four heartbreaking days of search.

Heinz, 22, vanished while walking home from Broncos Bar in La Crosse, Wisconsin at about 2:30 a.m. Sunday, according to the La Crosse Police Department.

She was last seen walking along the Mississippi River waterfront at about 3:30 a.m., and later spotted on surveillance footage walking in the direction of her apartment, which was three-quarters of a mile away.

Her body was found in the river just before 10:30 a.m. local time Wednesday near Brownsville, Minnesota—more than a dozen miles from her last known location.

Partners include the La Crosse City Police Department, Radisson Hotel La Crosse, University of Wisconsin-La Crosse, Viterbo University and Western Technical College.

As the school year had not yet started, it is unclear if the program was operating on the night of Heinz’s disappearance.

River Watch did not immediately respond to inquiries from Fox News Digital.
