There may be a break in a more than half-century-old cold case after central Minnesota authorities discovered human remains in a car submerged in the Mississippi River on Wednesday.The Stearns County sheriff says someone fishing Sunday on the Mississippi River near Sartell spotted what looked like a car on their sonar.

Investigators believe the human remains are connected to an unsolved 1967 missing person case involving a man named Roy Benn.

The car found in the Mississippi River near Sartell belonged to a man who has been missing for nearly 58 years.
