The Olmsted County Sheriff’s Department has identified the man whose body was found in the rubble left by a fire earlier this week at a rural home east of Rochester.

Officials say investigators determined 57-year-old Donald Helgerson died of a self-inflicted gunshot wound. A shotgun was found next to the victim after firefighters from Eyota and Dover extinguished the blaze that destroyed his home in Viola Township on Wednesday.

The cause of the fire remains under investigation.
