The son of Dallas and Mary Gilman, Delmont Gilman was adopted by James H. Campbell, possibly because his mother had died in childbirth. His body was found between the tracks of the Monon Railroad by an engine crew in the early morning hours of March 15, 1936.
It was unclear whether Gilman had been assaulted or simply hit by a train while intoxicated. He had been involved in a fight at the White Swan, a tavern at 214 W. 6th Street earlier in the evening, and some friends had taken him to the Binkley & Sullivan filling station at 7th Street and Morton Street to clean up.
John R. Duncan, another man involved in the fight, was later tried, along with Charles Billmeyer, proprietor of the White Swan, and Elmer Brinson, a bartender.
