This seems like something I’d expect to hear about Hugo or Hastings well before Nokomis:

Bloomington explosives case expands with munitions find

Military-grade ammunition was found Tuesday at a south Minneapolis building linked to a man jailed the day before on suspicion of having military explosives at his home, Minneapolis police said.

A federal investigation that remains closely guarded by authorities became public Monday during a search of the man’s Bloomington house. The investigation continued Tuesday at a commercial retail building at 5200 47th Av. S., which is owned by the man’s wife, said Minneapolis Police Deputy Chief Rob Allen. The findings in Minneapolis are not as worrisome as those in Bloomington, he said.

Having military grade munitions along the Hiawatha corridor is probably looked down upon by the ATF. That’s a popular road for shuttling presidents from the airport to downtown.
