The Delaware County Historical Society says someone broke into its building in Hopkinton overnight stealing several items dating back to the 1800s.

The items include approximately 40 arrowheads, a silver tea set, and Indian moccasins and vest.

Kay Miles never expected anyone to ransack the place. A place she says is part of the heritage of Hopkinton.

"Oh it's still alive and people take an interest yes. They realize how important and valuable this is for historical knowledge and their own history of themselves," Miles said.

But overnight, dozens of Native American artifacts went missing.

"They actually took the window and moved all this out, glass was here and removed the framing around and pulled out the piece of glass," Randy Kreutner said.

Museum staff say the choice of items is peculiar. Some items were taken, others were put in different spots throughout the museum.

"We just wonder if they got spooked or something and could only carry so much," Kreutner said.

No matter the reason, the museum just wants these artifacts returned.

"Bring it back to us, and we will no questions asked," Miles said.

And it says it'll make this community and building whole again.

"Those possessions are part of us," Miles said.
