About ten years ago, when I was actively buiding an Anderson Family website, I was contacted by a lady who said she was the Grand Daughter of th man who murdered Morgan. Her story was that her Grand Father was broken out of Jail by his brother and they took off west to Wyoming and Washington state. Her Grand Father changed his name and became a sucessful rancher and a model citizen. His family did not his story until after he died and his brother told them the story of the murder, trial and escape.
I may still have the letters if you are interested. John Anderson. email@example.com
