Otter Tail County resident finds suspected grenade while sorting boxes

A box-sorting cleanup in Otter Tail County turned into a public-safety call when a resident came across a suspected grenade, a reminder that old military items can surface in the middle of ordinary spring cleanouts, estate sorting and cabin-season unpacking.

The discovery was folded into the Otter Tail County Sheriff’s Office blotter roundup for April 21-27, the same stretch that also included a barn fire and a semi truck losing an axle while hauling corn. In a rural county, those calls can land in the same weekly report: a hazardous object in one home, fire response in another, and a mechanical breakdown on the road in between.

The sheriff’s office says its daily activity report is updated daily, and the county’s public-safety pages describe the office as dedicated to providing excellent service, building trust, reducing crime and creating a safe environment. The grenade report fits that pattern of routine transparency, where residents can see that deputies are handling far more than major crimes, including fire calls, assistance requests and 911 transfers.

The reason a suspected grenade is treated so seriously is simple. Minnesota law tightly regulates explosive devices, and the Minnesota Department of Public Safety says explosive licenses are required for companies that manufacture, assemble, sell, warehouse or store explosives, blasting agents or ammunition. Federal guidance also notes that bomb squads are often called to homes where decades-old military explosives are found, which is why objects that look like ordnance should never be treated as collectibles or scrap metal.

That risk has played out elsewhere in Minnesota, too. In Freeborn County, three live grenades were discovered at a history center and safely removed with bomb-squad help. The episode served as a sharp example of how a forgotten item can still be dangerous long after it was first brought home or stored away.

For anyone opening boxes in a barn, garage, attic or storage shed, the message from that kind of call is plain: stop sorting, keep your distance and contact law enforcement right away if an object looks like an explosive or old military device. In Otter Tail County, where the sheriff’s daily log captures everything from fire calls to lost-and-found entries, the grenade discovery is another sign that the most ordinary cleanup can suddenly become a job for professionals.
