A bomb squad and a police tactical team respond to a home, after a suspicious discovery some 30 minutes away.

51-year-old Donald Milner is being held in the Eau Claire County jail. Officers arrested him at his home on Saturn Avenue, after the Sheriff’s Department found explosive devices – described as grenades – at a storage shed in Fairchild.

Court records show Milner was found guilty in 1996 of being in possession of improvised explosives.

Milner is scheduled to be in court Friday morning.

"You get in a neighborhood thinking safe, calm neighborhood,” said Cristin Shong, who’s lived in the area for almost 5 years.

Lt. Tim Golden, with the Eau Claire Police Department says officers executed a search warrant at 3137 Saturn Avenue early Thursday evening.

But he says they arrested Milner before they even got in the door.

"He was very cooperative,” Lt. Golden said. “He was taken down to the Police Department and questioned."

That’s when Lt. Golden says the Marathon County bomb squad, federal agents with the ATF and the Eau Claire Police tactical team started their search.

"We're finding items that would lead us to believe that there are not only weapons here, but additional ammunition and so forth, but certainly nothing that would be considered explosive or grenades or anything like that,” Lt. Golden said.

Still, Lt. Golden says Milner – who is a convicted felon – isn’t allowed to have things like that in his house.

"We don't have any information that he's gonna' be using these weapons, but just the fact that he is possessing them is a violation,” Lt. Golden said.

Shong says the whole thing has her worried.

"We have kids here,” she said. “This is, to me this is a safe neighborhood. I mean schools are close, everything is close."

Lt. Golden says there’s no danger to the public.

"It's actually very scary,” Shong said. “It makes me feel like what else could, I mean, that scares me. I think of my kids and what else could happen."
