Thanks, I found this article....the full message is copywright of the New York Times...This first paragraph gives the gist.

KNOXVILLE, Tenn., Jan. 7.--To-day, at 11 o'clock, at Sweet Water, 42 miles below here, Thomas G. Boyd, Mayor of the town, was shot and killed by his nephew, Joseph L. Boyd, in the house of Mrs. Alvin Boyd.
Jan. 7 1882

I believe this Boyd is J C Vaughan's brother-in-law.
