A body was found in northeastern Minnesota this week, and police suspect it's a homicide.
Officials say they believe the body had been in the former iron ore mine less than 24 hours.
The victim's identity is not yet known. The body has been described as a white male with brown hair, in his early 20s, and standing about 5-foot-8 to 5-foot-11.
Authorities say they're not sure how the victim died, but they believe it was a homicide.
The sheriff's office and Bureau of Criminal Apprehension are investigating.
