Details of Disappearance

Duenke was last seen standing on a chunk of ice that was floating in the Missouri River near Washington, Missouri on December 27, 2022. He had his orange carbon fiber paddle, a water bottle, a green dry bag and a black crate of supplies with him. He was not in apparent distress at the time, and no one saw him go into the river itself. He was supposed to be picked up downstream, but never arrived at the designated spot.

In April 2025, Duenke's remains were found along the river near Chesterfield, Missouri, about a thirty-minute drive from where he was last seen floating on the icea. His identity was confirmed five days later.
