ALBERT LEA — The Freeborn County Sheriff’s Office and the Minnesota Bureau of Criminal Apprehension are investigating after a property owner discovered skeletal remains at the edge of his land Monday evening along Interstate 90.

A preliminary assessment indicates the remains are believed to be those of a male, according to Freeborn County Sheriff Kurt Freitag. They appear to have been there for at least a couple of years.

The remains were found near a fence along the south side of Interstate 90, about a half mile east of Minnesota Highway 13.

Freitag said the property owner went out to remove garbage near the interstate fence Monday evening when he saw what appeared to be a human skull. He called 911.

Authorities also discovered shoes, deteriorated clothing and a ring.

The Bureau of Criminal Apprehension crime team arrived in the area Tuesday morning and investigated at the scene.

Freitag said the remains will be taken to the Ramsey County Medical Examiner’s Office to determine possible cause of death.

More information will be released once the preliminary autopsy is completed.

The sheriff said there are no known missing people in Freeborn County who can be connected with the investigation.
