A gold ring was found with some human remains discovered this week along Interstate 90 near Albert Lea, the Freeborn County Sheriff's Office announced Thursday. Officials are hoping that releasing details about that ring and a pair of shoes will help identify the body.

The 10-karat gold ring, shaped like a class ring, features a large red stone. The shoes, made by the Mario De Gerard brand, "are in such poor condition that photos won't be useful," according to the sheriff's office.

The cause of death was not determined in a preliminary autopsy, a news release stated. A more detailed autopsy will be conducted soon.

A man whose property abuts the highway spotted the remains Monday while collecting litter.

On Tuesday, investigators from the sheriff's office and the Minnesota Bureau of Criminal Apprehension cut away brush, branches and saplings to get to the bones. Some had sunk a couple inches into the soil, Freeborn County Sheriff Kurt Freitag said.

Freitag said the bones appear to be from a man and, judging from their condition, have been lying next to the highway's south side for several years.

There are no active missing-person cases in Freeborn County. The sheriff's office is asking people with information to call 507-377-5205.
