KANSAS CITY, Mo. (AP) — A federal indictment accuses a Missouri man and others of breaking into a prehistoric Native American archeological site and using shovels, rakes, and other tools to dig up artifacts, causing hundreds of thousands of dollars in damage.

Seventy-year-old Johnny Lee Brown of Clinton was charged in an 11-count indictment filed April 26 but unsealed and made public on Tuesday.

The indictment alleges that Brown, two known co-conspirators, and others, excavated archeological items from federal land at Truman Lake near the town of Tightwad, Missouri, at least 10 times from June 2016 through September.

It’s unclear what was done with the items allegedly taken from the site.
