After nearly six decades, authorities in central Minnesota have confirmed the identity of human remains found in the Mississippi River as Roy George Benn, who went missing in 1967.

Benn, then 59, was last seen at a café in Sartell early one September morning. He was reportedly carrying a large amount of cash, and his disappearance sparked a long-running investigation with no resolution—until now. On August 10, a fisherman using sonar near Sartell detected what appeared to be a submerged vehicle. Dive teams recovered a heavily deteriorated 1963 Buick Electra, registered to Benn, with human remains and personal items inside.

The Minnesota Bureau of Criminal Apprehension has confirmed the remains are Benn's.  The investigation into how Benn and his vehicle ended up in the river continues.
