Bizarre synchronicity in two seemingly unrelated deaths

Ed Payne's wizardry continues. In an email message from him I received today -- excerpted below -- he describes the coincident circumstances of the unrelated deaths, years apart, of, respectively, a daughter and her likely father. The daughter was my father's half-sister, Shirley, the fourth of Elma Rose McLemore's five children. Shirley was killed by a drunk driver while she was getting off a school bus when she was eight years old. The father was presumptively Shirley's, one of Elma's five baby daddies.

From Ed's message:

"[F]ound an article describing the accident that took the life of Elma's daughter, Shirley Moore. And this is where it gets weird. Shirley was killed by a drunk driver on December 17, 1937, as your father noted in his chronology. I decided while I was at it to look for a grave inscription for David W. Holmes, the lawyer / county attorney who your father's chronology suggests might have been Shirley's father. His grave was listed in "Forrest County Tombstones" so I looked for a newspaper obituary. I missed it the first time because it wasn't in the back pages; it was a big story on the front page. The newspaper reported that Hattiesburg mayor David W. Holmes died when his car was involved in a head on collision with another vehicle containing "six drunken negroes." The date Mayor Holmes died was December 17, 1950--13 years to the day after the death of Shirley Moore."
