Police have released more details about the incident on Sunday in which a man in Crow Wing County had his hand blown off by homemade explosives.
The Crow Wing County Sheriff's office has identified the injured party as James Cummings, who was found at the property on the 42000 block of County Road 36 in rural Emily, Minnesota, with extensive hand injuries.
It emerged he'd sustained the injuries while working with homemade explosives, prompting a bomb squad to be called to the scene.
Found at the property were "several known and unknown chemicals" that are consistent with making explosives, including flash powders and Tannerite, the sheriff's office said.
"Evidence at the scene indicates that the injured victim ... was attempting to manufacture homemade exploding targets when the accident occurred," it added.
"It appears that this type of activity was going on for some time at this residence."
The sheriff's office says there's "no indication that there was any criminal intent" by Cummings.
Nonetheless, deputies will forward their reports to the Crow Wing County Attorney for consideration of any possible charges.
Cummings was treated until paramedics arrived and took over, and was later airlifted via a Life Link helicopter to St. Cloud Hospital.
The explosive materials were destroyed by the bomb squad.
