Farmington - Bank representatives cleaning out a foreclosed home in Farmington have stumbled upon 130 guns, 20,000 rounds of ammunition together with what appeared to be a grenade and a mortar. Police dispatcher Tom Sevigny said on Saturday that an investigation showed the guns were legally registered to the resident. The grenade and mortar turned out to be inert. Sevigny says police have seized the weapons and authorities will not file charges against the owner. The guns included shotguns and handguns.
