Answer:
Yes and yes
Explanation:
To both questions I think that I would hear the case and do something about it and I would definitely order the accused to be sent back to United States because people during Reconstruction deserves to be heard and that serving on a court in Indian Territory might not be such a bad idea. I don't really want to just ignore the case entirely because what if some people want this case solve badly? Then that would not end well.
I hope this helped.
