A cadaver search dog found the body of a man near Superior, which is east of Rock Springs, on Tuesday, according to a news release Wednesday.

Sweetwater County Sheriff Mike Lowell and Sweetwater Coroner Dale Majhanovich said the body was found through employment of a special cadaver search dog.

Lowell said the discovery is likely related to an active missing person case from 2015.

The remains are being taken to Loveland, Colo., for an autopsy.

“We are reasonably certain of the person’s identity, but do not wish to speculate until the identification is confirmed,” Lowell said.

Officials said they hope to make a positive identification by Friday, and plan to release more information then.
