Authorities recovered the body of a missing Wisconsin graduate student, Eliotte Heinz, from the Mississippi River on Wednesday after a devastating four-day search effort.

Heinz, aged 22, disappeared while heading home from Broncos Bar in La Crosse, Wisconsin, at approximately 2:30 a.m. on Sunday, as reported by the La Crosse Police Department (LCPD).

She was last observed walking by the Mississippi River waterfront around 3:30 a.m. and was later captured on surveillance footage heading towards her apartment, which was about 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. 

They stop anyone walking into the park after closing time, and guide those who may be potentially intoxicated away from the river, according to the River Watch website.

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.

UW-La Crosse and River Watch declined injuries from Fox News Digital.
