He was eventually caught when an undercover FBI agent began corresponding with him about buying some of the items, prosecutors said.

D’Ambrosio pleaded not guilty by video at his arraignment in Great Falls, Mont., and was released without bail. A message left with his attorney wasn’t immediately returned.

D’Ambrosio lived in Montana for many years and has written for several newspapers there, according to his author bio online. He has written numerous books about Montana, including “Montana Murders: Notorious and Unsolved,” “Montana Entertainers: Famous and Almost Forgotten,” and “Shot in the Dark: A History of Big Sky Cinema.”

He has also written books on other topics, including a biography of actor Charles Bronson, several biographies of boxers and a book about notorious National Hockey League enforcers.

A spokesperson for the Montana Historical Society said the museum, based in Helena, Mont., was cooperating with authorities and had been reviewing its security protocols.
