I found accounts of these two deaths in the Newton Weekly Ledger of Newton, MS. I don't have any family from this area nor am I related to these persons, but felt this might be interesting to someone.

A negro, by name Allen Walker, of Jackson, got on a spree one day last week, and while standing on Capitol street with a loaded double-barreled shotgun in his hands, H.C. Carter, a mulatto from Vicksburg, passed by, and without the slightest provocation, the drunken fiend leveled his gun and shot at him. He failed to hit his man however, but struck a negro named Nathan Thompson. The shot proved fatal. Allen was arrested.

A railroad accident occured on the Vicksburg-Meridian railroad, just below Edward's Depot, last Saturday morning. Two children were killed. One was eight-years-old and the son of Mr. Joseph A. McCain of this county. The other a little negro of Hinds county. The children were looking out of the windows when the train passed over a broken rail and the coach turning over threw them under it.
