@NorCalCherylLyn The MN Historical Society is updating their digital library platform and as such it isn't available until (soon?). BUT they do have a decent guide to their resources, e.g.;
https://libguides.mnhs.org/crime
https://libguides.mnhs.org/institutions/prisons
Recommend contacting them; HS tend to be super knowledgeable.
Some digitalized Rochester Newspapers (search Rochester and narrow to desired years): https://newspapers.mnhs.org/jsp/PsSearchResults.jsp
Hope this helps
@b4cks4w thank you!! I give it a whirl…
