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.

Sartell police say human remains were discovered inside a sunken car located on Wednesday in the Mississippi River. The sunken car was originally spotted on Sunday when a fisherman detected it on his sonar finder and reported it to authorities.

Authorities in central Minnesota say human remains were recovered from a vehicle pulled from the Mississippi River late Wednesday — and they say it may be connected to a missing person case from 1967.
