I'm frankly amazed that the MNHS has records, because retired NWA people and the NWA History Center told me that Delta would have everything, and Delta won't answer me. At any rate, I see the entry in the MNHS index and have asked my sister in St Paul if she's willing to go look at it. Thank you very much for the lead. How do you know this stuff?
As for Cook County, I'd heard about that, and the obvious records to get from them are autopsy files, and I'm not real sure I'm ready for that. It's only been 55 years, after all. Give it some time.
Thank you for the clippings. I think I have most of that after searching newspaper archives, but I'm going through them.
