There is a small write up about him in the Union Pacific Coal Company Employee Magazine, but it does not mention he died in a mining accident. No surprise there. So I pulled his obituary from the news paper.
His obituary says he was working in No. 8 mine. He was struck by falling timber in the abdomen, causing severe internal injuries. He was rushed to the hospital.
I have his obituary and I copied the article in the Coal Company Magazine. I can mail it to you, if you could get a hold of me. (307) 872-6435 or email firstname.lastname@example.org
