Minnetonka Police responded to a home on Baker Road, near the intersection of Orchard Road, on the report of a medical situation on July 31 at 8:15 a.m.
First arriving officers found an adult male, deceased, in the yard of the home.
Minnetonka Police Chief Mark Raquet said they are treating the death as a suicide.
"At this point, we don't have any reason to believe it was anything other than a suicide, although we're still continuing our investigation," he said.
Raquet said the person left a note that made officials nervous of what may be in the house, so they called in the HazMat (hazardous materials) team and the Bloomington Bomb Squad.
